Stratigraphy
| Formation: | Peebles Dolomite | Local bed: | 83MK2, 29.3 m |
Lithology and environment
| Primary lithology: | argillaceous dolomite |
| Environment: | shallow subtidal indet. |
| Geology comments: Vuggy, according to strat column. Fossiliferous. Pervasive dolomitization, difficulty in determining original carbonate textures. No (almost) qtz. silt. Probably skeletal packstones. Abundant skeletal material only in lower Peebles beds, corresponds with rapid increase in upper beds of gypsum crystals. Poor preservation of conodonts in Peebles indicates most or all are allocthonous. Very shallow, high energy water, increasing salinity. | |
