摘　　要：地球物理测井(简称测井)利用各种先进仪器在钻孔中连续观测,可获得钻孔剖面物理、几何、化学等各种原位信息,是中国大陆科学钻探(CCSD)工程的重要组成部分和关键技术之一.在岩芯与测井深度对齐、测井环境校正的基础上,建立了各种氧化物与测井曲线的关系方程,重建氧化物剖面,统计分析了主孔榴辉岩、片麻岩、角闪岩、蛇纹岩的氧化物特征,分析了榴辉岩、片麻岩、蛇纹岩的化学性质.按矿物成分、化学成分等对榴辉岩的分类进行了论述.根据副片麻岩和正片麻岩的氧化物差异,利用氧化物交会图识别副片麻岩和正片麻岩.利用氧化物交会图分析了蛇纹岩、金红石榴辉岩、角闪岩、正片麻岩、副片麻岩的原岩.Geophysical well logging（shortening logging）is one of important and key part of Chinese continental scientific drilling（CCSD）.Advanced logging equipment and well logging methods were used in main hole of CCSD.A lot of valuable rock information（physical,chemical,geometrical parameters of borehole＇s profile）had been obtained in-situ.Based on the environment correction of log curves and depth correction of core,the relationship equations of log curves and oxides had been established by multiple regression analysis.The oxide＇s profiles had been built,and statistical analysis of the oxide＇s characters and chemical properties of eclogite,gneiss,amphibolite and serpentinite had been made.According to the oxide＇s difference between paragneiss and orthogneiss,the paragneiss and orthogneiss had been recognized using oxide＇s cross plot.The origin rocks of eclogite,gneiss,amphibolite and serpentinite had been analysed by oxide＇s cross plot.
