太古宙下部地壳流体研究现状

stable isotope evidence[J]. Contribution to Mineralogy and Petrology 1984 , 85: 158 - 173. A Review of Researches on Fluids in Archean Lower Crust

太古宙下部地壳流体的研究对于阐明麻粒岩相变质作用成因及深成地质作用过程具有重要意义。下部地壳流体的性状、成因、运移方式及其与麻粒岩相变质作用成因联系等方面取得了一定的研究成果。采取流体包裹体研究与脱水变质反应平衡热力学计算、矿物对地质温压计估算等相结合的方法才能获得更可信的结果。实验研究是今后重要的发展方向。

The researches on fluid of Archean lower crust play an important role to demon-strating the genesis of granulite - facies metamorphism and geological process in the depth. Some research results have been obtained about the component, physical characteristics and mi-gration mechanism of fluid in Archean lower crust, and their relationship to genesis of granulite - facies metamorphism. The author believes that the reliable results mentioned above can only be obtained by synthetic comparation of data from fluid inclusions and thermodynamic estima-tions of dehydration reaction together with independent results from geothermobarometry. And experimental research is an important and tend in the future.
