Stratigraphy comments: STRATIGRAPHIC RELATIONS: From what Scott (pers comm., 1911) referred to as the "Mount Hope Fm". Lithostratigraphic relationships are unknown, but presumably the unit locally overlies the Gatun Fm. THICKNESS: Unknown stratigraphic thickness. AGE: Pleistocene, presumably (given geographic position) the Early Pleistocene. STRATIGRAPHIC POSITION: From the oyster bearing later.
Lithology and environment
Primary lithology:shelly/skeletal unlithified carbonaceous siltstone
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Coral mud, with corals and coralline fragments and many molluscan remains,mixed with more or less silt containing small species. LITHIFICATION: Unlithified, based on figured specimens and age.
Environment:lagoonal/restricted shallow subtidal
Geology comments: ENVIRONMENT: Shallow marine, siliciclastic-dominated setting adjacent to reef facies.
