Lithology and Thickness
Total thickness of about 6000m, this formation consists of an evaporitic lower unit including salt, anhydrite, paper shales, and plastic clays. The upper unit consists of dark red-brown gypsiferous marl and sandstone. The two units are subdivided by a key bed of green marl (which contains brackish-water fossils). The upper unit contains occasional plant remains and rare mammalian bones and footprints.
Lithology Pattern:
