Mesozoic radiolarians from the western part of the Atsumi Peninsula, Southwest Japan
OHBA, Hotaka

1997-12
The western part of the Atsumi Peninsula is underlain mainly by the Upper Paleozoic-Mesozoic sedimentary complex composed of chert, siliceous shale, shale and sandstone. Middle Triassic radiolarians such as Triassocampe coronata Bragin were obtained from bedded chert. Early Jurassic radiolarians of the Parahsuum simplum and Trillus elkhornensis zones were obtained from bedded chert, bedded siliceous shale and shale. Middle Jurassic radiolarians of the Laxtorum (?) jurassicum and Tricolocapsa plicarum zones were obtained from bedded siliceous shale and shale. On the basis of lithology and radiolarian fossils, the sedimentary complex of the western part of the Atsumi Peninsula is divided into three units : Lower to Middle Jurassic melange unit that consists of chert and shale, Middle Jurassic sandstone and shale unit that consists of sandstone and shale, and Middle to Upper? Jurassic sandstone and chert unit that consists of sandstone and chert.
