Stratigraphy
Member:Brown Bed
Stratigraphic resolution:bed
Lithology and environment
Primary lithology:bentonitic,concretionary,brown poorly lithified "shale"
Includes fossils?Y
Environment:lagoonal/restricted shallow subtidal
Glacial or sequence phase:transgressive
Geology comments: "The microfossil recovery from these two sections indicates a fairly shallow, restricted marine environment."; "Therefore it seems more likely that the contact relationship between the two units is one of restricted marine deposits transgressing over shallow lagoonal sediments after a depositional hiatus."
