地球深部脱气是地球历史上大气CO2变化和古气候变化的一个重要强迫因子。对于新生代,大气CO2变化的关键驱动机制仍然存在争议。在这里,我们分析了三个阶段的碰撞相关的岩浆活动在西藏,这对应于时间的三个主要阶段的大气CO2变化在新生代,并探讨这些现象之间的因果关系的可能性。为此,我们提供了西藏三个阶段岩浆岩的地球化学数据,并利用这些数据为模型提供信息,计算与新生代新特提斯向大陆俯冲演化相关的大陆碰撞引起的CO2排放通量。我们模拟的CO2排放率和全球大气CO2曲线之间的相关性与印度-亚洲碰撞是新生代大气CO2变化的主要驱动力的假设是一致的。“地球脱气是一个关键的碳源,但其对新生代大气CO2变化的贡献并不为人所知。在这里,作者分析了青藏高原的CO2通量,并认为印度-亚洲碰撞是过去65 Ma大气CO2变化的主要驱动力。
Deep Earth degassing is a critical forcing factor for atmospheric CO2 variations and palaeoclimate changes in Earth’s history. For the Cenozoic, the key driving mechanism of atmospheric CO2 variations remains controversial. Here we analyse three stages of collision-related magmatism in Tibet, which correspond temporally with the three major stages of atmospheric CO2 variations in the Cenozoic and explore the possibility of a causal link between these phenomena. To this end we present geochemical data for the three stages of magmatic rocks in Tibet, which we use to inform a model calculating the continental collision-induced CO2 emission flux associated with the evolving Neo-Tethyan to continental subduction over the Cenozoic. The correlation between our modelled CO2 emission rates and the global atmospheric CO2 curve is consistent with the hypothesis that the India-Asia collision was the primary driver of changes in atmospheric CO2 over the Cenozoic. “Earth degassing is a critical carbon source, but its contribution to Cenozoic atmospheric CO2 variations is not well known. Here, the authors analyse CO2 fluxes on the Tibetan Plateau and suggest that the India-Asia collision was the primary driver of changes in atmospheric CO2 over the past 65 Ma.”
