中文摘要：

榴辉岩石榴石-单斜辉石（Gt-Cpx）地质温度计常用于研究超高压变质作用p-t条件。业已存在多种Gt-Cpx温度计算公式和绿辉石Fe2＋校正方法,本文通过碧溪岭地区浅色及深色2种榴辉岩p-t条件计算,对几种常见温度计算公式和绿辉石Fe2＋校正方法进行比较,认为Droop（1987）电价平衡法和Ravna（2000）温度计算公式最适合榴辉岩的温度计算。计算结果表明,碧溪岭地区浅色榴辉岩峰期变质p-t条件为3.0～3.4GPa和660～731℃。

英文摘要：

Garnet-clinopyroxene（Gt-Cpx） geothermometer is very important in constrain of the p-t conditions of the ultrahigh pressure eclogites.Several Gt-Cpx temperature formulas and Fe2 ＋ adjustments for omphacite have been applied.Light-colored and dark-colored eclogites from Bixiling,eastern Dabieshan,were investigated with above methods.Charge balance for Fe2 ＋ in omphacite （Droop,1987） and the formula of Ravna （2000） are mostly suitable for light-colored eclogite,but not for the dark-colored one.Based on our calculation in this study,the ultrahigh-pressure metamorphism of the Bixiling eclogite took place at the p-t conditions of 3 ～ 3.4 GPa and 660 ～ 731 ℃.
