| 摘 要： | 简要介绍泥质变质岩中常用的温度计和压力计,对其可适用性、适用范围、质量优劣等进行了评述。经过对这些温度计和压力计的比较研究,我们发现石榴石-黑云母温度计、石榴石-白云母温度计、石榴石-蓝晶石(夕线石、红柱石)-斜长石-石英(GASP)压力计、石榴石-黑云母-斜长石-石英(GBPQ)压力计、石榴石-白云母-斜长石-石英(GMPQ)压力计、石榴石-黑云母-白云母-蓝晶石(夕线石、红柱石)-石英(GBMAQ)压力计、石榴石-金红石-钛铁矿-斜长石-石英(GRIPS)压力计的准确度较高,可以为地质工作者所采用。二云母温度计、白云母-斜长石温度计准确度还有待大幅度改进。石榴石-金红石-蓝晶石(夕线石、红柱石)-钛铁矿-石英(GRAIL)压力计、石榴石-堇青石温度计和石榴石-堇青石-蓝晶石(夕线石、红柱石)-石英(GCAQ)压力计等温压计的准确度及其可适用性,还有待于进一步研究。

| Abstract: | This paper briefly discusses the applicability, validity and error source of the geothermometers and geobarometers applicable to metapelites. Through comparative studies, we have found that some thermobarometers are valid and applicable, including the garnet-biotite and garnet-muscovite geothermometers, and the garnet-aluminosilicate-plagioclase-quartz (GASP), garnet-biotite-plagioclase-quartz (GBPQ), garnet-muscovite-plagioclase-quartz (GMPQ), garnet-biotite-muscovite-aluminosilicate-quartz (GBMAQ) and garnet-rutile-ilmenite-plagioclase-quartz (GRIPS) geobarometers. The present two-mica and muscovite-plagioclase geothermometers are not valid and cannot be applied. Still some thermometers and barometers need to be studied in order to evaluate their validity and applicability, including the garnet-cordierite geothermometer and the garnet-cordierite-aluminosilicate-quartz (GCAQ) and garnet-rutile-aluminosilicate-ilmenite-quartz (GRAIL) geobarometers. |
