Stratigraphy
Formation:Karkar
Stratigraphic resolution:formation
Stratigraphy comments: STRATIGRAPHIC RELATIONS: Unknown lithostratigraphic relationships. AGE: Middle to Late Eocene on the basis of macrofossil biostratigraphy, but presumably from the Late Eocene part of the formation. STRATIGRAPHIC POSITION: Presumably a checklist for the entire formation.
Lithology and environment

Includes fossils?Y
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Limestone is predominant, but also marls and shales rich in fossils. LITHIFICATION: Unknown.
Environment:open shallow subtidal
Geology comments: ENVIRONMENT: Nearshore or just offshore environment, tropical conditions. Open shallow subtidal carbonate setting is inferred.
