Stratigraphy
Lithology and environment
Primary lithology: | gray lithified sandy "limestone" |
Lithology description: Fauna is sampled from conglomerate boulders which "usually consist of pure, fine-grained limestone ranging in color from light to dark gray, the latter often assuming a purplish hue. Quartz sand may occur in these limestones, and in a few instances its percentage is so high that the rock might rather be designated as a calcareous sandstone." | |
Environment: | marine indet. |
