    A is composed mainly of massive and matrix supported conglomerates with coarse sandstones. Facies B is made up of coarse sandstones, massive sandstones, laminated sandstones and lenticular sandstones. The paleoenvironmental interpretaüon of the facies described is the braided river in tectonic valley with lateral alluvial fan deposits
