| 英文摘要 | O-18/O-16 and D/H of coexisting feldspar, quartz, and biotite separates of twenty samples collected from the Ertaibei granite pluton, northern Xinjiang, China are determined. It is shown that the Ertaibei pluton experienced two stages of isotopic exchanges. The second stage of O-18/O-16 and D/H exchanges with meteoric water brought about a marked decrease in the delta O-18 values of feldspar and biotite from the second group of samples. The DIH of biotite exhibits a higher sensitivity to the meteoric water alteration than its O-18/O-16. However, the first stage of O-18/O-16 exchange with the O-18-rich aqueous fluid derived from the dehydration within the deep crust caused the Delta O-18(Quartz-Feldspar) reversal, it is inferred that the dehydration-melting may have been an important mechanism for anatexis. It is shown that the deep fluid encircled the Ertaibei pluton like an envelope which serves as an effective screen to the surface waters. |
