MELFI, Adolpho J.; GIRARDI, Vicente A. V. e MONIZ, Antônio C.. Mineralogy of the soils of the Experimental Station "Theodureto de Camargo" - Campinas. Bragantia [online]. 1966, vol.25, n.1, pp.9-30. ISSN 1678-4499. http://dx.doi.org/10.1590/S0006-87051966000100002.
The present paper studies the mineralogy of monotypic series determined at the Experimental Station "Theodureto de Camargo". The region is geologically characterized by the presence of a Mesozoic diabase still intruded in a carboniferous glacial sedimentary formation. The existent soils represent weathered products either of rocks-sedimentary or igneous kinds - or a mixture of both. The Chapadão series derived from diabase is classified as "purple latossol", commonly known by the name of "terra roxa legítima". The Taquaral series also results mainly from diabase but has been largely contaminated by glacial sedimentary products as revealed by the presence of zircon, monazite, sillimanite, tourmaline, rutile, garnet, staurolite and kyanite. The Venda Grande, Barão and Monjolinho series result from clayey, silty and sandy glacial sediments. The Pomar series made up of products of carboniferous clay and silt sediments: exhibits notwithstanding an important mineral contribution from diabase.
