Diffusion of subsurface oxygen intensifies the pyrite oxidation during baseflow stages of the Indus headwater

To trace the subsurface pyrite oxidation in the Indus headwater at Leh, India, a time-series sampling was carried out for one year (Sept. 2021- Sept. 2022) on a weekly to biweekly basis. The data contain the inversion results for cationic and sulfate sources.
