概要

• 論文の詳細を見る

• We found earliest Triassic (Griesbachian) conodont, Hindeodus parvus, from the basal part of the black carbonaceous claystone of the Ubara Permian/Triassic boundary section in the Tamba Belt. We also obtained Late Permian (Changxingian) conodonts from the underlying gray siliceous claystone as already reported from other P/T boundary sections. The lithologic boundary between the gray siliceous claystone and the black carbonaceous claystone is confirmed to be the Permian/Triassic boundary in deep-sea sedimentary rocks.
