【摘要】 通过对赣中相山地区前寒武纪正、副角闪岩矿物学、岩石-地球化学特征系统对比研究,得出角闪岩成因判别标志的几点新认识:①提出了识别正、副角闪岩的角闪石矿物学标志;②阐明了区分正、副角闪岩的稀土元素地球化学特征;③对角闪岩微量元素地球化学特征提出采用模糊聚类分析与蛛网图相结合进行成因判别的有效方法;④提出综合应用15种元素对的比值(Ti/V,Ce/Yb,La/Yb,Th/Yb,La/Sm,La/Nb,Ce/Y,Rb/Sr,Nb/Y,Sm/Nd,Sr/Y,Sr/Ba,Zr/Y,Ti/Zr,Ti/Y)作为判别角闪岩成因的标志。更多还原

【Abstract】 Comprehensive study on petrology,mineralogy and geochemistry of REEand trace elements for the Xiangshan Precambrian ortho-paraamphibolites led to genetic recognition criteria for genesis of amphibolites as follows: ① The mineralogical features of amphibole for discrimination between ortho and paraamphibolites;② Explaination of the different REE geochemical characteristics of ortho,paraamphibolites;③ A useful method of fuzzy cluster analysis on trace elements amphibolites in combination with spidergram to discriminate ortho and paraamphibolites;④ The comprehensive application of 15 correlative element couple(Ti/V,Ce/Yb,La/Yb,Th/Yb,La/Sm,La/Nb,Ce/Y,Rb/Sr,Nb/Y,Sm/Nd,Sr/Y,Sr/Ba,Zr/Y,Ti/Zr,Ti/Y) to discriminate ortho and paraamphibolites is confirmed.更多还原
