| Stratigraphy comments: the paper discussed that the Winnitinny Creek member should be equivalent to the base of the Stage 3, which equals to the beginning of Atdabanian. | |||||
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. | |
