Este artigo tem como objetivo apresentar as grandes feições litoestratigráficas e tectônicas regionais de formação da bacia do Rio Paracatu. Pelo viés da abordagem regional, elucidam-se as questões referentes aos resultados de expressão superficial da bacia pela interação dos processos exógenos com as estruturas profundas. São elaborados mapas de litoestratigrafia, estruturas rúpteis, estruturas dúcteis, estereogramas e modelos visuais de geologia estrutural. Demonstra-se como a formaçao do Domo de Cristalina gerou dobras de descolamento anteparadas pela Serra de São Domingos, dando origem às esturutras de sinclinais e anticlinais das Cristas de Unaí.

This paper presents the lithostratigraphy and major regional tectonic processes that molded Paracatu River Basin. Through the regional analysis approach, an investigation is undertaken on how the exogenous processes and the in-depth structures interacted, resulting in the superficial expression of the basin. The results are maps for lithostratigraphy, brittle and ductile structures, stereograms and visual models for structural geology. The paper demonstrates how the Cristalina dome emerged and generated detachment folds, shielded by São Domingos Ridge, originating the synclinal and anticlinal structures of Unaí Crests.
