| 摘 要： | 太行山含夕线石石英球花岗岩是南营片麻岩的重要组成部分,其地质特征、地球化学和Rb-Sr 同位素特征表明它们是中下地壳副变质岩深熔熔浆和残留体混合的粥状体沿着伸展变形带运移、侵位和结晶形成的。其Rb-Sr等时线年龄为t= 1.933±0.08Ga,形成的时代为吕梁期。

| Abstract: | The granites with Sill-Qz ball are an important part constituted Naying gneisses of Taihangshan precambrian complex. Their characters in geology, geochemistry and Rb-Sr isotope indicate that they are the products of transfer, intrusion and crystallization of an mixer of melting bodies and melting remnants(Sill-Qz ball)along an extensional deformation zone(Chengnanzhuang extensional deformation zone). The mixers are formed by anatexis of the parametamorphic rocks in middle lower crust. We have acquired their Rb-Sr isochron age, t =1.933?0.08Ga, which show that their formative times is during Luliang period. |
