Última Pedodiagenetic Characterization of Cretaceous Paleosols in Southwest Minas Gerais, Brazil Rev. Bras. Ciênc. Solo Nascimento,Diego Luciano do; Ladeira,Francisco Sergio Bernardes; Batezelli,Alessandro. ABSTRACT The influence of post-burial geological processes on preserving pedogenic properties has great importance in identifying ancient paleosols both in the field and in a laboratory. However there are not many publications that focus on characterizing paleosol diagenesis. As temperature and pressure progressively increase, evidence of pedogenesis is modified and destroyed, hindering paleoenvironment characterization and interpretation. This paper discusses diagenetic evidence and its relation to strictly pedogenic features, like structure, cements, nodules, and neoformation of clay minerals using the carbonate paleosols of the Marília Formation in the upper unit of the Bauru Basin as a case study. Despite the long geotectonic and thermal history of the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Marília Formation; Pedogenesis; Diagenesis.

Bras. Ciênc. Solo Silva,Márcio Luiz da; Batezelli,Alessandro; Ladeira,Francisco Sérgio Bernardes. ABSTRACT Deduction of associated paleoenvironments and paleoclimate, definition of the chronosequence of paleosols, and paleogeographic reconstruction have become possible through the application of micromorphology in paleopedology. Micromorphology has also been useful in recognition of weathering processes and definition of minerals formed in succession. In this respect, the objective of this study was to identify the development of pedogenic processes and discuss their significance in the paleoclimate evolution of the Marília Formation (Maastrichtian) of Bauru Basin. Three sections of the Marília Formation (A1, A2, and A3) were described, comprising nine profiles. Micromorphologic al analysis was carried out according to the specialized literature. In...
