摘要:

大陆硅酸盐岩风化及碳酸盐岩埋藏是从地表碳库中移除二氧化碳的关键地质过程,被广泛认为对调节全球大气二氧化碳水平和地球气候演化具有重要意义。一直以来,准确评估大陆硅酸盐岩风化通量及其二氧化碳消耗通量是地球科学研究的一个重要前沿领域。鉴于此,本文系统梳理了量化硅酸盐岩风化通量的计算模型及关键参数,评述了各模型的优缺点和适用范围,并对未来如何更准确量化硅酸盐岩风化通量进行展望。此外,基于现有的风化通量计算模型,本文还全面评估了全球硅酸盐岩化学风化消耗的二氧化碳通量,并对因风化作用引起的气候变化提出定性/定量的判别依据。

Abstract:

Weathering of continental silicate rocks and subsequent carbonate burial are crucial geological processes for removing carbon dioxide from surface carbon pools, and are widely recognized that is important for regulating global atmospheric carbon dioxide levels and the evolution of Earth's climate. Accurate assessment of the weathering flfluxes of continental silicate rocks and their CO2 consumption flfluxes has long been a signifificant frontier of geoscientifific research. In this view, this paper systematically compiles the calculational models and their key parameters for quantifying weathering flfluxes of silicate rocks, reviews the advantages, disadvantages, and scope of each model, and anticipates how weathering flfluxes of silicate rocks can be more accurately quantifified in the future. In addition, based on the existing weathering flfluxes calculation model, the global CO2 flfluxes consumed by chemical weathering of silicate rocks are comprehensively assessed, and a qualitative and/or quantitative basis for discriminating climate change due to weathering is proposed.
