A Find of the Usuginu-Type Pebbles from the Hitachi Mining District and its Geologic Significance
TL;DRAbstract
The Paleozoic strata distributing in the Hitachi mining district are divided into the four units which are, in the ascending order, the Akazawa, the Daioin, the Ayukawa, and the Omika formations (Kuroda, 1959).Though we have no information about their geologic age except some Visean fossils found from limestone of the Lower Ayukawa formation (Hujimoto, 1924), it has been said that these formations may be lithologically correlatable in many respects to those Paleozoics of the southern Kitakami Mountains and the Soma district of the northern Abukuma Plateau.* ) Studies in the granite-bearing conglomerates in Japan, No. 19.
