GUADALUPIAN AND LOPINGIAN (MIDDLE AND LATE PERMIAN) RADIOLARIANS FROM CHERT BLOCKS WITHIN CONGLOMERATE OF THE MINO BELT, SOUTHWEST JAPAN

Abstract

Capitanian (late Guadalupian, Middle Permian) and Changhsingian (late Lopingian, Late Permian) radiolarians were obtained from chert blocks within the conglomerates of the Kamiaso Complex of the Mino Belt in Awano, Gifu Prefecture, central Japan. The former contains 15 species assigned to 10 genera with 4 undetermined species, and the latter contains 5 species assigned to 11 genera with 9 undetermined species. The chert blocks were presumably derived from an accretionary complex prior to accretion on the oceanic plate.
