Jarosite formation in deep Antarctic ice provides a window into acidic, water-limited weathering on Mars

The authors report in-situ formation of jarosite witin the Talos Dome ice core (East Antarctica) and show that this ferric-potassium sulfate mineral is present in ice deeper than 1000 meters and progressively increases with depth. This has implications for the presence and formation mechanisms of ja...
