Atmospheric Carbon Dioxide Reconstruction and Ocean Acidification Deduced from Carbon Isotope Variations across the Triassic-Jurassic Boundary in the Qiangtang Area, Tibetan Plateau

摘要

Objective The end-Triassic mass extinction was one of the five most profound Phanerozoic extinction events.This event was accompanied by a series of significant environmental changes,of which the most notable is the emergence of warm climate and the world-wide disappearance of carbonate platform.C isotope is one of the main means of reconstructing palaeoenvironment,however,there are
