[2] The formation comprises arenites with a few thin clayey inter-beds.

The sands overlie micro-conglomeratic bodies up to 1 metre (3.3 ft) thick.

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.

Small channels, up to 1.5 metres (4.9 ft) over a very short distance, cut the arenitic bodies.
