Lithology and environment
Primary lithology:black "shale"
Secondary lithology: ash
Includes fossils?Y
Includes fossils?Y
Lithology description: The Pembina Member is a black shale rich in selenite and is lithologically very similar to the Pierre Shale. The destructive effects of selenite form by weathhering are quite evident in both formations and often result in the loss of small bones. [most material reported comes from active bentonite mines] from ref 9541 (1999)
Environment:marine indet.
