| 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.
