Research Abstract

Oceanic environmental changes of whole Triassic interval have been examined on deep-sea sedimentary rocks from SW Japan and New Zealand. Through the geochemical, paleontological and paleomagnetic studies, we have obtained the following results, 1) Oceanic Anoxic Event (OAE) of early Triassic did not occur uniformly, and their magnitude depended on depositional areas. 2) A Late Triassic OAE has been detected, which is strongly related to fluctuation of Carbon cycle in ocean, and 3) isotopic profiles such as C-isotope for whole Lower Triassic and Upper Triassic to Lower Jurassic have been clarified.
