.... Precambrian carbonate rocks are abundant in the intracratonic Sao Francisco Basin composed mostly by microbial facies. Gas has been registered only in seeps and in a few wells. Paleozoic carbonates are only significant in the Solimoes and Amazonas basins but no commercial discoveries were obtained up to now...

... ABSTRACT The Cambro-ordovician sediments of the South East Saharan platform show a facies evolution from continent to platform rather than platform to basin; that is the reason why the faciologic stratigraphy (Homewood and al., 1992) is applied. The genetic sequences, are limited...
