Stratigraphy
Lithology and environment
Primary lithology: | tuffaceous,gray poorly lithified silty,sandy claystone |
Includes fossils? | Y |
Lithology description: Consists for the most part of sandy or silty clays with minor partings of ash. Its color ranges from dark gray to light gray. Poorly lithified based on fossil preservation. | |
Environment: | deep-water indet. |
Geology comments: Molluscs found in assemblages of the Shinzato Tuff Member occur in depths as much as 300 m, although some can be in shallower water. Generally the assemblage should be regarded as deep-water. |
