N and C Isotopic Compositions of the Lower Triassic of Southern Primorye and Reconstruction of Habitat Conditions of Marine Organisms after Mass Extinction at the End of the Permian

摘要

Data on the N and C isotopic composition are presented for the Lower Triassic claystones of the Abrek section of southern Primorye (Far East). The results showed five N isotopic intervals and several negative C isotopic excursions of the Induan-lower Olenekian stages of the Abrek section.
