摘要
在克孜勒塔格地区开展的1∶5万区域地质矿产调查工作,初步查明了此区古元古代变质花岗岩的岩石学、岩石化学等特征,对该期侵入岩的岩体成因及就位机制进行了探讨,并对其形成时代进行了推断。岩体侵位明显受线状构造("X"型剪裂隙)控制,说明该区域在地壳演化早期存在,岩体就位以构造扩展机制为主。其侵位时间为古元古代晚期。
Based on the work of 1 ： 50 000 regional geological-mineral survey in Keziletage, it preliminarily finds out the petrology and petrochemistry of palaeoproterozoie meta-granitoid. This paper discusses the rock genetic and emplacement mechanism of the palaeoproterozoic intrusive rock, and deduces the formation age. Emplacement is significantly controlled by linear structure, indicating that the region exists in early stage of the crustal evolution. Emplacement time is Late paleoproterozoic.
