Lithology and environment
Primary lithology: | gray,green lithified calcareous siltstone |
Lithology description: Olive-gray marl/siltstone | |
Environment: | deep subtidal ramp |
Geology comments: Proximal storm deposits, which were colonized by large epifaunal bivalves during quiet phases. Accordingly, they most likely represent deposits of the middle shelf, between the mean fair weather wave base and the storm wave base. |
