Chemical frost weathering of olivine: Experimental study and implications

摘要

New experimental results are reported on the frost weathering of olivine. After first weathering, a decrease in Fe sup 2()M(2) absorption bands were noted. This decrease is related to the protonation of O() in the mineral. It is contented that this reaction may result in the regolith storage of 100 to 1000 m of H(sub 2) over the history of Mars.
