Abstract

Six-teen H chondrites with various degrees of weathering were investigated using several types of in-situ measurement to reveal the mechanism of Antarctic alteration in this study. As a result, a depleted REE pattern with a positive Ce anomaly and a deposition of unbonded REEs with a negative Ce anomaly were observed in cracks. In conclusions, the remarkable observations are explained by terrestrial alteration following chemical leaching among cracks, but this alteration occurs locally only.
