Lithology and environment
Primary lithology: | "limestone" |
Environment: | lagoonal/restricted shallow subtidal |
Geology comments: succession of massive carbonate, bioclastic grainstones alternating with micritic and microbial laminated carbonates.135 m thick and suggests a rapid change in depositional environment from a moderate to high energy, shallow water biohermal platform to a more restricted, low energy, intrashelf, and possibly slightly deeper lagoonal environment. |
