Lithology and environment
Primary lithology:pyritic,black "shale"
Secondary lithology:green,red or brown mudstone
Includes fossils?Y
Lithology description: "Black shale with pyrite in sequence of green, friable mudstone, olive calcareous mudstone,and argillaceous dolomite (below), and green and red mudstone (above)."
Environment:lagoonal Tectonic setting:foreland basin
Glacial or sequence phase:regressive
Geology comments: "The lithology and associated biota appear to indicate a very shallow, marginal marine setting, possibly lagoonal and probably brackish...A BA 1 assignment is reasonable."

2003:04:06 SEP environmental call based on liimited lithologic description and overall context of Salina Formation (to which Vernon has been refered to as member by some authors). NOTE: stratigraphically near evaporites and within a restricted basin; periodically experiences more normal marine conditions with increased tidal flushing
