摘要

Hydrogen isotopic composition was measured using an ion microprobe for lherzolitic shergottite in Martian meteorite GRV 99027 from the Grove Mountains in Antarctica. The D/H ratios of phosphate whitlockites were analyzed and water concentrations of tested points were calculated. The result show that their δ D values vary from +1300‰ to +4700‰, and water contents from 0.04 wt% to 0.43 wt%. Comparing the results with the hydrogen isotopic compositions of whole rock, hydrous miner- als and phosphates in SNC meteorites indicates that water highly enriched in deuterium is a unique feature of Martian meteorites, especially the phosphates prominent. It is interpreted as the result of isotopic exchange between magmatic water and Martian crustal fluids. The high D/H ratios observed in GRV 99027 phosphates indicate that they have hydrogen isotopic compositions similar to those of apatite in other Martian meteorites. The results further con- firmed the association of GRV 99027 with the Martian meteorite group.
