Martian hematite、oxidative hydrothermal alteration、XAFS、cosmic spherules

Oxidative hydrothermal experiments on reproduced I-type cosmic spherules are carried out to be applied on the formation mechanism of Martian hematite spherules. XAFS analysis on run products revealed that oxidation of I-type cosmic spherules could progress in neutral conditions rather than acidic conditions.
