Stratigraphy
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: Equivalent in part to Read Bay Formation. |
Lithology and environment
Primary lithology: | gray,green dolomite | ||
Includes fossils? | Y | ||
Lithology description: Lithology not stated. I think the implication is that it continues the samples from lower down in this same section. "Dolomite (limy); finely crystalline, thin to medium bedded, wavy, undulatory, badly fractured; light olive-grey to grey-brown, weathering pinkish grey-white to pale yellow-orange; quite fossiliferous..." | |||
Environment: | shallow subtidal indet. | Tectonic setting: | passive margin |
Geology comments: Deposits in this region are of two general kinds: shallow-water stable carbonate platform (generally in the NW part of Arctic Archipelago) and deeper basinal facies (generally to the SE). This collection is in the former.
