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

G. Baccolo, B. Delmonte, et al.

Discover how jarosite, a ferric-potassium hydroxide sulfate found in Martian sediments, has been identified within deep Antarctic ice. This remarkable study, conducted by Giovanni Baccolo, Barbara Delmonte, P. B. Niles, and others, reveals the intriguing interaction between aeolian dust and atmospheric aerosols, shedding light on the geological importance of paleo-ice processes on Mars.
