Varvelike rhythmites, usually laminated siltstones and shales with scattered clasts, are known from outcrops and well cores of the upper Cabecas Formation in the Parnaiba (Maranhao) Basin, Brazil, with sediments laid down under glacial and periglacial conditions. Palynological study from different lithologies, indicates a latest Famennian age (LN Zone). Sedimentological approach of one rhythmite indicates that the grain-size contrast clearly separate between silt and sand layers but that all… CONTINUE READING
