Formation:Witten Limestone
Stratigraphic resolution:formation
Stratigraphy comments: Blackriveran, Camarocladia beds
Lithology and environment
Primary lithology:fine,gray "limestone"
Includes fossils?Y
Lithology description: Even-bedded, dense, fine-grained limestones; golden gray prevails, but locally dark dove grays, hyacinth grays, and light beige grays predominate. Weathered surcfaces are considerably lighter than the fresh rock. The thickness varies from 45 to 75 feet and averages about 60 feet. Thin ribbon beds of coarse-grained limestone form minor intercalations.
Environment:carbonate indet.
