Pyrite oxidation plays a critical role in the relationship between weathering and climate, and its impact on the global carbon cycle has previously been constrained through inversion models utilizing observations of river sulfate (SO₄²⁻) and its ³⁴S/³²S isotope ratio (δ³⁴S_(SO₄)). However, measureme...
