摘要: The Paint Pots are a natural Fe–SO4 acid spring system along the Kicking Horse Rim, major geological feature that has controlled fluid flow and mineralization over geologic time. very low pH (∼3) extremely high trace metal concentrations of springs anomalous greatly exceed health limits (Zn = 35.8 mg/L, Pb 0.461 mg/L, As 82.7 ppb). Sulphur isotopes (δ34S δ18O in sulphate equal to +11.4 –12.1 ‰, respectively) consistent with sulphide oxidation. Mass balance calculations indicate must have derived their acidity content from weathering pyrite-rich ore deposit vicinity. Several types occur Mississippi Valley Type (MVT) style being most source waters. At outlet, Fe-rich waters oxidize, forming large cone features Fe–O precipitates, predominantly goethite. A diverse microbial community been identified site is di...
