Description
The formation comprises
arenites with a few thin clayey inter-beds. The sands overlie micro-conglomeratic bodies up to thick. Two-dimensional ripple marks (with wavelengths of nearly ), larger ripples (wavelengths of ), interference ripples, and mud cracks were recognized. The arenitic beds are also characterized by internal structures such as accretionary laminae, coalescent bodies, low-angle lamination, and cross stratification. Some arenitic levels are deeply
bioturbated, both by simple vertical tubes and by larger horizontal ones. Rare small wood fragments were recognized. Small channels, up to over a very short distance, cut the arenitic bodies.
