Ratio of Na to K in feldspars as a predictable index to trace the source of sediment: Based on the mass-balance model combined with feldspar weathering kinetics and a case study

摘要

The Na/K ratio in feldspars in sediment has been proven to be a stable and predictable index. The relationship between the sediment and its source in terms of the Na/K ratio in feldspars can be defined using the massbalance model combined with the feldspar weathering kinetics as
