| 摘 要： | 辛格尔一带的前震旦纪古老变质岩系为一系列的变质核杂岩。其内核由早—中太古代古陆核组成 ,外核为晚太古代、古元古代、中元古代、新元古代早期变质岩系构成的多层次构造增生楔 ,并有多期剥离断层配套。新元古宙代晚期震旦系为盖层。它是地壳多期伸缩构造的产物。变质核杂岩体是一个有利于成矿的构造体系。辛格尔变质核杂岩构造是一个对有色和贵金属等矿产成矿的有利构造

| Abstract: | The pre- Sinian metamorphosed rocks in the Qinggir area consist of a series of metamorphosed nuclues complexes.Its inner core is composed of Early- Middle Archean paleo- continental nuclues,and its outer core composed of metamorphosed rocks of L ate Archean,paleo- Proterozoic,meso- Proterozoic and ear- ly Neo- Proterozoic which form multi- layered tectonic accretionary prisms,accompanied by multi- phase desquamation faults.The Sinian of the neo- Proterozoic forms the cover.The metamorphosed nuclues com- plexes resulted from multi- phase extension- compression of the crust,which are favorable for the mineraliza- tion.Qinggir metamorphosed nucleus complexes structure is also favorable for the mineralization. |
