一般注記This paper describes Upper Triassic lime-stone clasts of the polymictic limestone conglomerate (Imogadaira Limestone) of the Mino Belt in the Nanjo Mountains, Fukui Prefecture, central Japan. The Imogadaira Limestone occurs as an isolated block in the Middle Jurassic mélange unit in the upper reaches of the Imogadaira River, Nanjo Mountains. The forma-tion exhibits a prevailing conglomerate fabric, charac-terized by dense packing of limestone clasts within a sparse matrix. The Imogadaira Limestone has a poly-mictic clast association, dominated by Permian lime-stones with lime mudstone and limestone clasts con-taining thin-shelled bivalves. Neither terrigenous clastic grains nor rock fragments occur in the Imogad-aira Limestone. Late Triassic conodonts and Late Tri-assic and Early Jurassic radiolarians were extracted from whole-rock samples of the Imogadaira Limestone.Further examination revealed that the Late Triassic conodonts and radiolarians occurred within limestone clasts containing thin-shelled bivalves.
