Quantitative Analysis of the Rate of Geochemical Weathering of Sulfur from Sedimentary Rocks Using Atmospheric Deposition, Concentration and River Discharge Data —A Case Study of the Mountainous Basin of the Tedori River, Japan, over a 16-Year Period

Quantitative analysis of the rate of geochemical weathering of sulfur (S) from sedimentary rocks (GeoS) was conducted using concentration (Cs) and discharge (Qs) data from the Tedori River and atmospheric deposition (AtdepS) in the basin. First, S fluxes were calculated using 16 years of Cs and Qs data. The annual average discharge of S (TotalS) was estimated at 8597 ton·year −1 (117.3 kg·ha −1 ·year −1 ). Of this, 1331 ton·year −1 was AtdepS (18.2 kg·ha −1 ·year −1 ) and another 7266 ton·year − 1
