ABSTRACT
There are similarities in the evolution and tectonic history of sedimentary deposits between
the Brazilian marginal basins, because of their comparable genesis, related to the disruption of
Gondwana. Based evolution, one can infer that there are similarities between the sedimentary
basins in west Africa and eastern of Brazil. The African basins have geological structures
comparable to those found in Brazil and have potential for the discovery of large volumes of
oil in localized areas of deep water. This work was developed through a bibliographic review
highlighting the characterization of source rocks by geochemical techniques of TOC, Rock-
Eval pyrolysis, vitrinite reflectance, thermal alteration index for assessing the source rock
potential and maturation of organic matter, as well as the techniques used for analyzing
biomarker. Complementing this work, we present the source rocks which occur in the basins
of the west african coast in order to establish possible correlations between the different
source rocks sampled in basins now separated by the Atlantic Ocean.
Key Words: Source Rocks; Geochemical Techniques; Biomarkers; Oil.
