概要 |
Part II of Geology of Akiyoshi is divided into four chapters. Chapter 1,2,3,and 4 concern the stratigraphy of the Ota, Gampi, Beppu and Tsunemori groups, respectively. In each chapter geographical dis...tribution,1ithology and fossil contents of the formations of each group are described, and correlation of them with fusulinid zones of the Akiyoshi limestone group and the geologic structure of each group are also discussed. So far as the paleontologic evidences are concerned, the Ota group is ranging from Middle Pennsylvanian? to Upper Permian; the Gampi group is referred with question to Middle Pennsylvanian, but it may be possible that it is Permian in age; the Beppu group is ranging from Lower to Upper Permian; and the Tsunemori group is representing only Middle and Upper Permian. All these groups of non-calcareous facies are considered to be autochthonous deposits and are assumed to take more complex geologic structures than hitherto believed.続きを見る
