该转型与杜内中期碳同位素漂移事件(TICE)同期发生, 研究组通过两个碳酸盐岩剖面的锂同位素(7Li)数据, remain an outstanding puzzle in Earths climate history. This transition coincides with the mid-Tournaisian carbon isotope excursion (TICE). It is hypothesized that intensified continental silicate weathering during this period sequestered CO, direct evidence for enhanced continental weathering has been lacking. We present lithium isotope (Li) data from two carbonate sections showing a ~12 decline during TICE. Integrating Li with carbon cycle models (GEOCLIM and COPSE) suggests silicate chemical weathering rates increased ~30% with declines in weathering intensity during the TICE event,现有假说认为, Keyi, 早密西西比亚纪(约359347 Ma)温室气候向冰室气候的转型,最终触发TICE正漂移, Cheng, and increased marine productivity, Li,。
