Dissecting mechanisms of chemical weathering in a rapidly uplifted watershed

抄録

The rates of silicate weathering have been correlated to various factors, such as lithology, temperature, runoff, and erosion rate for major river systems. We carried out periodic field campaigns to sample various materials in a small river system in SE Taiwan where the uplift and exhumation is rapid. These data suggest that pyrite oxidation, carbonate weathering, and mixing processes mostly account for the solute variation pattern.
