Aspectos lithoestratigraficos da Formacao Uberaba, Cretaceo da Bacia do Parana.

The Uberaba Sandstone formation with local expression in the city of Uberaba (State of Minas Gerais) and vicinities, has been focused from different lithostratigraphic points of view. In spite of its characterization by previous authors as a formation, its geographic distribution as well as its relationship with other units of the Parana sedimentary basin has never been adequately elucidated. Simultaneously with a better characterization of the Uberaba Formation petrographic properties, the authors redefine its geographic distribution and suggest a possible stratigraphic relationship with other formations of the Bauru Group which have been defined in the State of Sao Paulo.-English summary
