资源简介：
利用牙形石钙同位素，恢复了二叠纪-三叠纪之交钙循环过程，识别出早三叠世多次海洋酸化事件。对华南牙形石样品进行钙同位素分析，得到了晚二叠到中三叠世（长兴期-安尼期）较连续的牙形石同位素变化曲线，揭示了该时期海水钙同位素变化规律。
Using calcium isotopes of conodonts, we reconstructed the calcium cycle during the Permian-Triassic transition and identified multiple ocean acidification events in the Early Triassic. We carried out calcium isotope analysis on conodont samples collected from South China, and obtained a relatively continuous isotopic variation curve of conodonts spanning the Late Permian to Middle Triassic (Changhsingian to Anisian stages), which reveals the secular variations of seawater calcium isotopes during this period.
