Aspectos da evolução termo-mecânica da Bacia do Parnaíba

In this paper, we intend to contribute to the a better assessment of the thermo-mechanical evolution of the Parnaíba Basin and to investigate its capability for hydrocarbons generation and accumulation. The study of intracontinental sedimentary basins, such as Parnaíba, is also useful for the understanding of the thermo-mecanical evolution of the continental lithosphere. Based on the non-uniform lithospheric stretching model of Royden and Keen (1980), backstripped subsidence and paleotemperatures curves were constructed for 20 PETROBRÁS boreholes using the program BASTA (Friedinger, 1988) modified by De Sousa (1996).
