在新元古代晚期的大的碳同位素漂移，大陆冰川作用和地层异常碳酸盐沉淀的重复协会提供了一个框架，解释这些条件的再现晚二叠世地球。一个古海洋学模型，开发来解释这些地层相关的现象表明，在晚二叠世缺氧深海的翻转引入了高浓度的二氧化碳到表层环境。预测的海洋和陆地生物的生理和气候后果是在很好的雅阁和选择性晚二叠世大规模灭绝的观察。
The repeated association during the late Neoproterozoic Era of large carbon-isotopic excursions, continental glaciation, and stratigraphically anomalous carbonate precipitation provides a framework for interpreting the reprise of these conditions on the Late Permian Earth. A paleoceanographic model that was developed to explain these stratigraphically linked phenomena suggests that the overturn of anoxic deep oceans during the Late Permian introduced high concentrations of carbon dioxide into surficial environments. The predicted physiological and climatic consequences for marine and terrestrial organisms are in good accord with the observed timing and selectivity of Late Permian mass extinction.
