Description
We carried out identification of tephra layers in the middle to lower Pleistocene Dochu Formation, Tokushima Prefecture. These tephras named locally Shiro tephra and Dochu tephra. Shiro tephra discovered at a construction site in Mima City, Tokushima Prefecture. Shiro tephra can be compared with Imakuma-II tephra, and Dochu tephra can be compared with Shishimuta-Pink tephra from central Kyushu, in terms of the similarities of petrography, refractive indices of volcanic glass and hornblende, and chemical composition of volcanic glass.
