对四川盆地西北部、中国南部和南阿尔卑斯山东部的卡尼期洪积岩剖面进行了碳酸盐岩定量岩石学分析。卡年雨季是发生在卡年早期和卡年晚期(晚三叠世)开始之间的一个气候变化期，与δ13C记录中多次急剧的负漂移相吻合，这被认为是全球碳循环扰动的证据。在CPE期间，海洋领域发生了相关的环境修改和生物转变。特别是，在四川盆地西北部和整个特提斯地区占主导地位的微生物碳酸盐台地经历了广泛的消亡，陆架碳酸盐沉积物中的微生物组分急剧减少，取而代之的是泥粒和骨骼颗粒。我们的结果表明，碳酸盐工厂的这种变化在特提斯范围内是一致的。最值得注意的是，东特提斯和西特提斯的微生物碳酸盐生产都在图瓦卢晚期恢复，恢复的时间不受这些遥远领域的盆地演化和地球动力学环境差异的影响。
Quantitative petrologic analysis on carbonates was carried out on stratigraphic sections encompassing the Carnian Pluvial Episode from northwestern Sichuan Basin, South China and eastern Southern Alps. The Carnian Pluvial Episode, or CPE, is a period of climate change that occurred between the early Carnian and the beginning of the late Carnian (Late Triassic) and coincides with multiple, sharp negative excursions in the record of δ13C that are thought to be evidence of perturbations of the global carbon cycle. During the CPE, relevant environmental modifications and biological turnovers occurred in the marine realm. In particular, microbial carbonate platforms, that were dominant in northwestern Sichuan Basin and throughout Tethys, underwent widespread demise and the microbial component in shelf carbonate sediments sharply decreased and was replaced by ooid- and skeletal grains. Our results show a Tethys-wide coincidence between this change in the carbonate factory. Most notably, both in eastern and western Tethys microbial carbonate production recovered in the late Tuvalian, and the timing of recovery was not influenced by differences of basin evolution and geodynamic setting that characterize such distant domains.
