Abstract

BARROS, Luiz Fernando de Paula; LAVARINI, Chrystiann; LIMA, Laura Souza  and  MAGALHAES JUNIOR, Antônio Pereira. Synthesis of the late-quaternary palaeobioclimatic scenarios in Minas Gerais state/southeastern Brazil. Soc. nat. [online]. 2011, vol.23, n.3, pp. 371-385. ISSN 1982-4513.  http://dx.doi.org/10.1590/S1982-45132011000300001.

In this paper, it was attempted to synthesize the natural palaeobioclimatic scenarios of the Late-Quaternary in Minas Gerais State, Southeastern Brazil, seeking for their relationship to large-scale climatic events. It was made an extensive literature review. It was looked for papers based on different methods, but with absolute datings and palaeobioclimatic implications. This kind of survey can not set precise time limits. However, some trends could be observed from the available datasets. It was proposed eight palaeobioclimatic scenarios for the last 50,000 years. The greater number of scenarios is usually found in the last 10,000 years. However, this proposal is still open due to concentration of the available data in just some regions, occurring information gaps.

Keywords : environmental changes; quaternary continental records. geochronology; Minas Gerais state.
