Geography
Country:Japan State/province:Okinawa
Coordinates: 26.2° North, 127.8° East (view map)
Paleocoordinates:26.3° North, 127.6° East
Basis of coordinate:estimated from map
Geographic resolution:outcrop
Time
Period:Quaternary Epoch:Pleistocene
Stage:Gelasian 10 m.y. bin:Cenozoic 6
Key time interval:Gelasian
Age range of interval:2.58800 - 1.80600 m.y. ago
Stratigraphy
Geological group:Shimajiri Formation:Shinzato
Stratigraphic resolution:bed
Stratigraphy comments: The uppermost part of the Shimajiri Formation. Shinzato Formation correlated with planktonic foram zones PL5/6 and nannoplankton zones CN12b (upper part), 12c, and 12d by Ujiie (1994). This spans the latest Piacenzian and Gelasian, but a Gelasian age is assigned here following Sato et al. (1999) and Komatsubara et al. (2005).
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.
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.

Reason for describing collection:taxonomic analysis
Museum repositories:USNM
