| 摘 要： | 苏北超高压变质带是秦岭—大别造山带的东延部分,所产出的榴辉岩有三种类型,分别为产于片麻岩中的G类榴辉岩、产于大理岩中的M类榴辉岩和产于蛇纹岩中P类榴辉岩。地球化学研究表明,三类榴辉岩的原岩复杂多样,源岩为下地壳或上地幔的基性-超基性岩,兼具大陆和大洋玄武岩的特征,富含TiO2等有用组分,是金红石矿床的成矿母岩。金红石矿床的形成是华北、扬子两大板块俯冲碰撞的结果,金红石成矿作用的强弱与岩性、构造、变质变形作用等密切相关。榴辉岩中含有金红石、钛铁矿、磷灰石、石榴子石、绿辉石等多种有用矿物,具有较高的综合利用价值。

| Abstract: | The northern Jiangsu ultrahigh-pressure metamorphic belt is the eastern extending portion of the Qinling-Dabieshan Orogenic Zone. According to the country rocks,the eclogites occurring in this belt can be classified into three types: G-type in gneiss, M-type in marble and S-type in serpentinite. Geochemical characteristics of eclogites show that their original rocks are complicated and related to mafic-ultramafic rocks derived from the lower crust or upper mantle with properties of both continental and ocea... |
