Research of Karatsu Coal Field. No.2

On the Unconformity between the Kishima Beds and Yoshinotani Beds (Kawago Beds)

Abstract

A new boring in Karatsu Coal Field No.2 revealed an unconformity between the Kishima beds and Yoshinotani beds (Kawago beds). The remarkable crustal movements that faulted and folded the Yoshinotani beds (kawago beds) prior to the deposition of the Kishima beds are correlative to the Savian phase. The movements are called the pre-Kishima phase.
