Lithology and environment
Primary lithology: | gray,green sandy mudstone |
Includes fossils? | Y |
Lithology description: "Unit A rapidly transitions from a sandy-mudstone to a 1.5 m thick wetland/lacustrine mudstone capped by a blocky gray calcareous mudstone horizon; that is predominantly a dense micritic limestone...The sandy-mudstone is dominated by illite and abundant silica." Layer is greenish gray (5GY 6/1). | |
