Lithology description: SPECIFIC LITHOLOGY: Hard, partly crystalline, compact, indistinctly bedded creamy coloured rock. Massive in parts but some layers are richly fossiliferous. LITHIFICATION: Lithified, based on facies description. | |
Environment: | shallow subtidal indet. |
Geology comments: ENVIRONMENT: Shallow marine, carbonate facies, probably adjacent to coral reef environments. |
