Stratigraphic relationships between the Colombian, Sinú Offshore and Sinú-San Jacinto basins based on seismic stratigraphy

Relações estratigráficas entre as bacias Colômbia, Sinú Offshore e Sinú-San Jacinto baseadas em estratigrafia sísmica

Abstracts

There are diverse controversial and contradictory models about the geological history of the Caribbean region. Some issues such as the origin of the Caribbean plate, the nature of basement of the Caribbean basins and the regional tectonics, have been in discussion during decades. There are disperse and punctual studies across the Caribbean. Application of seismic stratigraphy in regional seismic lines across the Colombian, Sinú Offshore and Sinú-San Jacinto basins suggests a stratigraphic continuity between these regions. A chronostratigraphic chart of the Colombian and Sinú Offshore basins based on stratal terminations and seismic facies was proposed. Seven stratigraphic stages were identified in the Colombian, Sinú Offshore and Sinú-San Jacinto basins, which, also, have been recognized across the Caribbean region. First stratigraphic stage was characterized by continental to restricted marine deposition during a Triassic/Jurassic rifting. Second, third and fourth stages correspond with deposition of a wide carbonate platform in the Cretaceous, sandy carbonate platform during the Paleocene and carbonate and coarse-grained fluvial sedimentation during the Eocene, respectively. Another stage was characterized by rising of base level and deep-water deposition (turbidites and pelagic/hemipelagic sediments) during the Oligocene. The Early to Middle Miocene was characterized by shallow marine to fluvial sedimentation during falling base level, which was controlled by episodic events of tectonic inversion. During the Late Miocene to recent, the sedimentation consisted of terrigenous coarse-grained deposits. Stratigraphic relationships between these zones, suggest a shared geological history between the Caribbean and northern South America. The geologic continuity founded in this study is easily explained by the model of an in situ origin for the Caribbean plate.

Existem diferentes modelos controversiais e contraditorios sobre a história geológica da região do Caribe. A origem da placa Caribe, a natureza do embasamento das bacias do Caribe e o contexto tectônico regional tem sido discutido durante décadas. Existem alguns estudos dispersos e pontuais na região do Caribe. A estratigrafia sísmica aplicada em linhas sísmicas regionais nas bacias Colômbia, Sinú Offshore e Sinú-San Jacinto sugere uma continuidade estratigráfica entre essas bacias. Neste estudo foi proposto uma carta cronoestratigráfica das bacias Colômbia e Sinú Offshore baseada em terminacões estratais e fácies sísmicas. Sete etapas estratigráficas foram identificadas nas bacias Colômbia, Sinú Offshore e Sinú-San Jacinto. Essas etapas também foram reconhecidas na região do Caribe. A primeira etapa estratigráfica foi caracterizada por deposição continental para marinho restrito durante um evento de rifting no Triássico/Jurássico. As segunda, terceira e quarta etapas foram caracterizadas pela deposição de extensas plataformas de carbonatos durante o Cretáceo, deposição de uma plataforma carbonática arenosa no Paleoceno e sedimentação carbonática e fluvial de grão grosso durante o Eoceno, respectivamente. Uma outra etapa foi caracterizada pelo aumento do nível de base e deposição marinha profunda (turbiditos e sedimentos pelágicos/hemipelágicos) durante o Oligoceno. O Mioceno Inferior e Médio foi caracterizado pela sedimentação marinha rasa para fluvial durante uma caída do nível de base controlada por eventos episódicos de inversão tectônica. Durante o Mioceno Superior até o presente a sedimentação foi principalmente terrígena de grão grosso. As relações estratigráficas entre as bacias Colômbia, Sinú Offshore e Sinú-San Jacinto sugerem uma história geológica comum entre o Caribe e o norte de América do Sul. A continuidade geológica proposta neste estudo é facilmente explicada pelo modelo in situ da origem da placa Caribe.

INTRODUCTION

Intensive exploratory activities of resources have improved the understanding of continental basins in local scale in North and South America. However, there are diverse and disperse studies along the Caribbean region. The studied area consists of the Sinú-San Jacinto, Sinú Offshore and Colombian basins in the northwestern region of the Colombian Caribbean (Fig. 1). About the Colombian, Sinú Offshore and Sinú-San Jacinto basins there are some studies, such as, Duque-Caro (1990)Duque-Caro H. 1990.

These studies, also reflect interpretations based only on lithostratigraphic features; and interpretation of data premised on the model of an allochthonous origin for the Caribbean plate.

There are not studies about the relationship between stratigraphic record of the Sinú-San Jacinto, Sinú Offshore and Colombian basins, neither about the relationship of those records with the geology along the Caribbean region. According with the hypotheses of the model of an in-situ origin for the Caribbean plate, the Caribbean region shows a shared tectono-stratigraphic history from south of North America to north of South America (Klitgord & Shouten 1986Klitgord K.D. & Schouten H. 1986.

The scope of this paper is: (1) to facilitate the correlation between the stratigraphic sequences of the northwestern zone of Colombia and the Caribbean region; (2) to demonstrate the stratigraphic continuity between the Colombian, Sinú Offshore and Sinú-San Jacinto basins; and (3) to propose a chronostratigraphic chart of the Colombian and Sinú Offshore basins using seismic stratigraphy procedure.

DATA AND METHODOLOGY

Seismic and well data were provided by the Ecopetrol and by the Agencia Nacional de Hidrocarburos of Colombia. Geological and age data were extracted from several well logs descriptions and biostratigraphic zones of some wells (Duque-Caro 2001Duque-Caro H. 2001. Biostratigraphic report of Colombian Caribbean Wells. Internal Report from Ecopetrol.) and from geological mapping (Gómez et al. 2007Gómez J.T., Nivia A.G., Montes N.E.R., Tejada M.L.A., Jiménez D.M.M., Sepúlveda M.J.O., Osorio J.A.N., Gaona T.N., Diederix H., Uribe H.P., Mora M.P. 2007. Mapa Geológico de Colombia escala 1:1.000.000. Instituto Colombiano de Geología y Minería.).

The seismic and well data were tied using a synthetic seismogram (Fig. 2). This seismogram was constrained from sonic log and checkshot data. The seismic sequences were defined by regional unconformities, using standard seismic interpretation procedure (mapping of stratal terminations) and seismic facies associations. Based on amplitude, continuity, frequency and geometry of seismic reflectors, a set of seismic facies units was mapped.

Figure 2.

The benthic and planktonic zones Ammonia Beccarii (N22-MN23), Uvigerina Subperegrina (N17-N19), Uvigerina Isidroensis (N17-N18), Guttulina Caudriade (N9-N8), Uvigerina Mexicana (N5), Cibicidoides Perlucida (P21-P22), Bulimina Jacksonensis (P10, P12, P17, P18/P19), Rzehakina Epigona (Duque-Caro 2001) were founded in the Pleistocene-recent, Pliocene, Late Miocene, Middle Miocene, Early Miocene, Oligocene, Eocene, Paleocene sequences.

The paleoenvironmental interpretations from seismic facies were correlated with these biozones and descriptions of drill-cores (Fig. 3). The typical deep-water and carbonate seismic facies found in this study have been detailed in several previous seismic facies models (e.g. Sangree & Widmier 1977Sangree J.B. & Widmier J.M. 1977.

Each seismic reflector was interpreted and converted via flattening to a time-space diagram. Seismic facies was merged to this diagram in order to produce the final chronostratigraphic charts. We compiled and reviewed several published studies along the Caribbean region to produce a chronostratigraphic chart which summarizes the stratigraphic record and sequences of the Caribbean region.

RESULTS

Nine seismic sequences from the Jurassic period to the present were recognized in the Sinú Offshore basin. Twelve seismic sequences from the Triassic period to the present were recognized in the Sinú-San Jacinto basin.

Each sequence was characterized by upper and lower terminations of reflectors and seismic facies associations. A total of twenty seismic facies were recognized in this study (Tab. 1). Stratigraphic surfaces and seismic facies were correlated with several calibration wells; they provided lithological and sedimentological data (Fig. 3).

Table 1.
Seismic facies used in this study (Alfaro & Holz 2014).

Triassic and Jurassic

Sinú-San Jacinto basin

The northern Sinú-San Jacinto basin is the best example of a Mesozoic rifting. Regionally the syn-rift sequences are thinning toward the eastern and western boundaries of the basin (Fig. 4). Seismic reflectors of these sequences are divergent toward the major normal faults, suggesting syn-rift deposition (Figs. 4 to 6).

Note the solution of focal mechanism in Fig. 1 suggests the dextral sense of strike-slip structure in this seismic line. (B) Interpretation of seismic facies. Description of each seismic facies unit is shown in Tab. 1. See location in Fig. 1.

The typical wedge-shaped geometry has been recognized in the Paleocene, Cretaceous and upper Jurassic sequences. High-amplitude, chaotic and low frequency reflectors are typical of the Jurassic sequence in the Sinú-San Jacinto basin (Fig. 6).

In the southern and central zone, seismic facies show wide areas of variable amplitude, intermediate to low continuity and high frequency reflectors. Reduced areas of variable amplitude, high continuity and intermediate to low frequency reflectors are dispersed. Interpretation of seismic facies suggests fine-grained sediment of wide areas of flood plain systems with influence of lobate lacustrine areas shattered across flood plains (Figs. 6 and 7). Syn-depositional normal faults continue controlling sedimentation.

Figure 7.
Chronostratigraphic chart built from seismic line in previous figure (Alfaro & Holz 2014). Note that the rifting event was characterized by continental to shallow marine sedimentation.

The Triassic record of the Sinú-San Jacinto basin is characterized by intermediate amplitude, low frequency and intermediate continuity reflectors, which are affected by syn-depositional high angle normal faults (Figs. 4 to 6). These seismic facies suggests the presence of continental sedimentation associated to grabens and hemigrabens during early stages of a rifting event. Coarse-grained fluvial sediments, fine-grained sediments related to flood plain and lacustrine systems are associated to this event (Figs. 6 and 7).

Sinú Offshore and Colombian basins

The Sinú Offshore basin was dominated by shallow marine sedimentation during the Lower Jurassic. Carbonate and fine-grained coastal plain sediments are typical in the Sinú Offshore area. Carbonate banks and reefs are characterized by high amplitude, high continuity and low frequency seismic facies (Fig. 8).

Figure 8.

Note that the high-angle normal faults and flower structures observed in the onshore zone are also recognized in the offshore area. Observe that the solution of focal mechanism in Fig. 1 suggests the dextral sense of strike-slip structure in this seismic line. (B) Interpretation of seismic facies in the Sinú Offshore and Colombian basins in the offshore Colombian Caribbean. Description of each seismic facies unit is shown in Tab. 1. See location in Fig. 1.

Sediments of coastal plain show low amplitude, chaotic pattern and variable frequency reflectors. The Colombian basin was filled by fluvial sediments during the Middle Jurassic. These sediments show intermediate to low amplitude, intermediate to low continuity and low frequency seismic facies. Deposition of coastal plain and fluvial sediments is recorded as growth strata related to high-angle normal faulting during a rifting event (Figs. 8 and 9).

Figure 9.

Observe that the rifting event was characterized by continental to shallow marine sedimentation. The Oligocene to Early Miocene was dominated by deep-water deposition during rising of base level, whereas, the Middle Miocene to recent was characterized by shallow marine to fluvial depositions.

Cretaceous

Sinú-San Jacinto basin

The Cretaceous sequence is characterized by variable amplitudes, intermediate to low continuity and high frequency seismic facies, which are shattered across wide areas of intermediate to low amplitude, low to chaotic and high frequency reflectors. Elongate and lobate lagoons placed across a wide coastal plain were deposited during that period.

Sinú Offshore and Colombian basins

In the Sinú Offshore and Colombian basins, sedimentation was characterized by high amplitude, intermediate to low continuity and low frequency seismic facies related to a sandy carbonate platform with some carbonate banks and reefs.

Paleocene

Sinú-San Jacinto basin

The Paleocene record is characterized by high amplitude, high continuity and high frequency seismic facies. Some zones show high amplitude, high continuity and low frequency reflectors. Interpretation of seismic facies indicates the development of a large-scale silty carbonate platform formed in the Sinú-San Jacinto basin.

Sinú Offshore and Colombian basins

In the offshore basins, seismic facies are characterized by low amplitude, high continuity and variable frequency reflectors. In the northernmost zone, reflectors have high amplitude, intermediate to low continuity and low frequency. Also, restricted zones with high amplitude, high continuity and low frequency seismic facies do occur.

During Paleocene, the Sinú Offshore and Colombian basins were controlled by deep-water sedimentation with some carbonate influence. Several carbonate banks and reefs were formed in the footwall of rift structures. Deep-water settings in these basins were related to late stages of a rifting event. During this period the sedimentation was contemporaneous with activity of normal faults.

Eocene

Sinú-San Jacinto basin

The Eocene sequence represents a wide carbonate platform. Three seismic facies related to carbonate settings were interpreted. Wide areas with high amplitude, high continuity and high frequency reflectors correspond with a silty carbonate platform. In the eastern and western zones, sedimentation was characterized by a carbonate platform with high siliciclastic input. Some seismic facies with high amplitude, high continuity and low frequency and zones with transparent seismic facies delimited by high amplitude reflectors suggest influence of carbonate banks and reefs.

Oligocene

Sinú-San Jacinto basin

The Oligocene was characterized by rising base level. Sedimentation was dominated by deep-water settings. Seismic facies consists of low amplitude, high continuity and variable frequency reflectors. Oligocene also was characterized by deposition of lobate turbidites, which show mounded seismic facies. The influence of carbonate banks also is evident in the Oligocene record.

Sinú Offshore and Colombian basins

The Sinú Offshore and Colombian basins were characterized by sedimentation on a slope system. Gravity-driven debris flow deposits were controlled by high angle slope and recorded seismic facies characterized by transparent to chaotic reflectors. Lateral changes of this seismic facies show hemipelagic to pelagic sedimentation toward the southern zone.

Miocene

Sinú-San Jacinto basin

Stratigraphic record of the Early Miocene in the Sinú-San Jacinto basin is poor. Seismic facies are characterized by low amplitude, high continuity and variable frequency reflectors. The Middle Miocene sequence was characterized by deep-water deposition. Seismic facies correspond to low amplitude, high continuity and variable frequency reflectors. Erosional truncations and growth strata, suggest a structural reactivation.

Older normal faults were inverted since Eocene and especially during Middle Miocene. Seismic facies of the Late Miocene sequence are characterized by high amplitude, high continuity and high frequency. Also, low amplitude, chaotic and variable frequency reflectors were identified in the western zone. This sequence is related with a silty carbonate platform and coastal plain settings in the western zone.

Sinú Offshore and Colombian basins

Seismic facies of the Early Miocene are characterized by low amplitude, high continuity and variable frequency reflectors. In the northernmost zone, seismic facies with wavy geometry were mapped. These seismic facies show lateral changes to high amplitude, high continuity and high frequency reflectors toward the southern zone, suggesting a south to north variation of depositional settings.

Facies are changing from mixed carbonate/siliciclastic platform in the south to deep-water settings characterized by slumps deposits in the northern area. These slumps are characterized by inclined reflectors related to depositional thrusting (Fig. 10).

Figure 10.
A) Seismic line uninterpreted in the Colombian Basin. (B) Slumps deposits deposited during Early Miocene, across a high angle slope in the Colombian basin. Observe the depositional thrusts, which are suggesting a flow direction toward northwestern

The Sinú Offshore and Colombian basins show lateral changes similarly to Early Miocene ones. Mixed carbonate/siliciclastic seismic facies are located in the southernmost area. Increase in deposition of marine deposits related to waves, debrites, submarine leveed channels and turbidites occurred in the Colombian basin (Fig. 11).

Figure 11.
(A) Seismic line uninterpreted in the Colombian basin. (B) Submarine leveed channels deposited during Middle Miocene in the Colombian basin. Seismic line in time (ms).

The Late Miocene sequence is seismically characterized by low amplitude, high continuity and variable frequency in the Sinú Offshore basin. In the Colombian basin, a sequence characterized by intermediate to low amplitude, intermediate to low continuity and high frequency reflectors was deposited. This basin also shows some zones of transparent seismic facies. During Late Miocene, the southern Sinú Offshore was dominated by a coastal plain, which was affected by a syn-depositional flower structure (Fig. 8).

Our proposal is that the oblique convergence between the Caribbean and South American plates (Fig. 1) suggests a transpressive regime, which has been controlled the falling base level and consequently the generation of incised channels in the Sinú Offshore basin (Fig. 12). The Colombian basin was affected by deposition on a mixed carbonate/siliciclastic platform with influence of some gravity-driven deposits controlled by a high angle slope.

Pliocene and Pleistocene-recent

Sinú-San Jacinto basin

The Pliocene sequence in the Sinú-San Jacinto basin is characterized by intermediate amplitude, high continuity and high frequency reflectors. Also, this sequence shows intermediate to low interbedded amplitude, intermediate amplitude and low frequency reflectors. This seismic signature indicates that the Sinú-San Jacinto area was dominated by highly siliciclastic sedimentation.

Deposition on a proximal deltaic setting was affected by episodic deposition of coarse-grained fluvial sediments. The Pleistocene to present is characterized by intermediate to low amplitude, intermediate to low continuity and low frequency seismic facies. This basin was dominated by fluvial sedimentation during Pleistocene to present.

Sinú Offshore and Colombian basins

The Pliocene sequence in the Sinú Offshore basin is characterized by variable amplitude, intermediate to low continuity and high frequency seismic facies. This basin was dominated by mixed carbonate/siliciclastic sedimentation. Carbonate banks and reefs, also, were deposited in this basin. During Lower Pliocene, fine-grained sediments related to flood plain were deposited.

In the Colombian basin, the Pliocene sequence shows low amplitude, chaotic and variable frequency seismic facies. Reduced areas are characterized by variable amplitude, intermediate to low continuity and high frequency seismic facies. This suggests that sedimentation on a coastal plain with little influence of a mixed carbonate/siliciclastic platform dominated the Colombian basin during Pliocene.

The Sinú Offshore basin is characterized by high amplitude, chaotic and variable to intermediate to high seismic facies. Also, this basin show intermediate to low amplitude, intermediate to low continuity and low frequency reflectors. The Sinú Offshore basin was dominated by fine-grained fluvial channels and flood plain sedimentation during Pleistocene; however, there is influence of canyons related to high-angle slope during late stages of Pleistocene to the present. The Pleistocene to recent in the Colombian basin is characterized by high amplitude, chaotic and intermediate to high seismic facies. This basin was mostly characterized by development of fluvial channels.

DISCUSSION

Seismic interpretation in this study suggests that sedimentation was controlled by a diachronic rifting event in the Sinú-San Jacinto, Sinú Offshore and Colombian basins during the Triassic to Paleocene. This event correlates with the Mesozoic rifting previously documented across the Caribbean region. It also has been characterized by the formation of red beds and evaporites in the Gulf of Mexico; volcanism in Cuba; red beds, carbonates, volcanic sills and flows in the Guajira Peninsula and Mérida Andes; volcanic and red tuffs in the Santa Marta Massif; thick sequences of marine sediments in North Range of Trinidad; sediments of neritic settings in the western area of Cuba; thick successions of dolomite in north of Cuba; red beds in the Perijá Sierra and Eastern Cordillera in northern Colombia and Venezuela; thick red beds with a northeast direction in the Maya and Chortis blocks in Central America and grabens and horst with a northeastern direction (MacDonald 1964MacDonald W.D. 1964.

A wide carbonate platform was deposited during Eocene in the Sinú-San Jacinto basin (Alfaro & Holz 2014Alfaro E. & Holz M. 2014.

This chert event has been also documented in the Florida Peninsula; Lesser Antilles and has been related to the seismic horizon A´´ in the Caribbean offshore (Mattson et al. 1972Mattson P., Pessagno E.A., Helsey C.E. 1972.

The Sinú Offshore and Colombian basins in this study, meanwhile, doesn't show evidence of Eocene record, which suggest a major erosive or non deposition event in these basins. This event is also suggested by low-sorting and thick flysch deposits in the Caribbean (Stainforth 1969Stainforth R.M. 1969. The concept of sea-floor spreading applied to Venezuela.

According to this study, lateral and vertical changes of seismic facies in the Sinú-San Jacinto, Sinú Offshore and Colombian basins, suggest a major falling base level event, during which shallow marine sediments shifted to continental sedimentation in the Miocene to recent. This event was characterized by a major pulse in the Middle Miocene, which, is recorded seismically in this study, as a regional erosive unconformity. This unconformity has been also recognized in Panamá, Dominican Republic and interior of the Caribbean plate (Biju-Duval et al. 1982Biju-Duval B.G., Bizon A., Mascle & Muller C. 1982.

Neogene stratigraphy, paleoceanography and paleobiogeography in northwest South America and the evolution of the Panama seaway. Paleogeography. Paleoclimatology. Paleoecololgy, 77:203-234.) (Fig. 1).

In the Interior Sierra in eastern Venezuela, occurred an important structural event during Middle Miocene. Erosive truncations of Miocene were observed in the southern boundary of Hess Escarpment (Alfaro et al. 2013Alfaro E. Barrera D.F., Rossello E.A. 2013. Diachronic Cenozoic wrenching in southwest of Colombian basin. Comunicações Geológicas, 100(1):55-65.).

According to the observations in this study, the Sinú-San Jacinto, Sinú Offshore and Colombian basins in northwest Colombia, show a shared geologic history. The seismic sequences of Triassic to recent in the Sinú-San Jacinto correlate with the sequences that have been interpreted in this study, in the Sinú Offshore and Colombian basins. These basins suggest events of shallow marine to continental sedimentation during a Mesozoic rifting.

The sequences deposited in the Oligocene and Early Miocene were characterized by deep-water sedimentation during an event of rising base level. The sequences of Middle Miocene to recent suggest major events of falling base level, which were characterized by shallow marine to continental settings. These observations suggest a stratigraphic and tectonic continuity between the Colombian, Sinú Offshore and Sinú San Jacinto basins.

Compilation from previous studies shows that the same sequences and events also can be traced along the Caribbean region (Fig. 13). Therefore, we suggest that the geologic features (tectonic and stratigraphic) founded in these basins have continuity along the Caribbean region. In fact, these observations are not adequately explained by the allochthonous origin of the Caribbean plate, due to the fact that the allochthonous model implies significant differences in the geological history of the Caribbean region, northern South America and southern North America.

Seven stratigraphic stages were identified in the Colombian, Sinú Offshore and Sinú-San Jacinto basins, which, also exist along the Caribbean region.

According to the allochthonous model, the Caribbean plate was formed during Upper Cretaceous near to the present-day, in the Galapagos hotspot in the Pacific Sea (Burke 1988Burke K. 1988.

On the other hand, the geologic continuity observed in this study, is easily explained by the model of an in-situ origin for the Caribbean plate, which proposes a conservation of stratigraphic trends along the Caribbean region, northern South America and southern North America. According with in-situ model, the Caribbean plate, was formed by the separation between North and South American plates during a Triassic to Jurassic intracontinental rifting (Ball et al. 1969Ball M.M., Harrison C.G.A., Supko P.R. 1969.

CONCLUSIONS

According with this study, we can conclude that:

1. Seven stratigraphic stages were identified in the Colombian, Sinú Offshore and Sinú-San Jacinto basins, which, also can be traced across the Caribbean region. This fact suggests a tectonic and stratigraphic continuity between these zones.

2. First stratigraphic stage was characterized by continental to restricted marine deposition during a Triassic/Jurassic rifting. Second, third and fourth stages correspond with deposition of a wide carbonate platform in the Cretaceous, sandy carbonate platform during the Paleocene and carbonate and coarse-grained fluvial sedimentation during the Eocene, respectively. Another stage was characterized by rising of base level and deep-water deposition during the Oligocene. The Early to Middle Miocene was characterized by shallow marine to fluvial sedimentation during falling base level, which was controlled by episodic events of tectonic inversion. During the Late Miocene to recent, the sedimentation consisted of terrigenous coarse-grained deposits.

3. This geologic continuity is easily explained by the model of an in situ origin for the Caribbean plate.
