Stratigraphy
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: Transition zone of interbedded volcanic and sedimentary rocks between the upper Crescent Formation and the overlying lower member of Mcintosh Formation (as used in the emended sense of Pease & Hoover, 1957). AGE: Middle Eocene; placed by enterer into younger of two Middle Eocene stages on the basis of stratigraphic position. STRATIGRAPHIC POSITION: Localities are about 2 m apart, in ascending stratigraphic order, in a 17-m-thick section.
Lithology and environment
Primary lithology:pebbly poorly lithified mudstone
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Pebbly mudstones. LITHIFICATION: Poorly lithified, on the basis of figured specimens.
Environment:marine indet.
Geology comments: ENVIRONMENT: The depositional environment is interpreted to have been on the flank of an oceanic volcanic island in outer shelf to upper slope (bathyal) muds subject to the influx of shells of nearshore and shallow-marine megainvertebrates and pebbly basalt debris.
