Stratigraphy

Formation:	Ichinotani
Stratigraphic resolution:	bed
Stratigraphy comments: according to Maekawa et al. (2018) Kasimovian conodont species in the float; float might be from the Triticites Zone of the Ichinotani Fm. (Harayama 1990); Limestone clasts may also derive from Permian conglomerates of the Sorayama Formation

Lithology and environment

Primary lithology:	"limestone"
Includes fossils?	Y
Environment:	reef, buildup or bioherm
Geology comments: lmst were deposited in an aerobic environment in the photoc zone, such as shallow reef; based on ostracods also a high-energy environment in a fore-reef ecosystem is possible
