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...

This has implications for the presence and formation mechanisms of jarosite observed on Mars.
