祁漫塔格地区构造-岩浆作用与成矿
Discussion on Tectonic-Magmatic Process and Mineralization in the Qimantage Region
-
摘要: 对祁漫塔格地区构造-岩浆作用的研究表明,岩浆活动峰期为加里东期—印支期,并有从北向南逐渐变新的趋势。区域成矿峰期与岩浆活动峰期是一致的,主要成矿母岩为岩浆弧相俯冲-碰撞杂岩。另外,祁漫塔格地区主要发育北东向和北西向两组断裂带,北东向断裂是影响区域成矿的主控因素。Abstract: The Qimantage Mountains region is a part of the East Kunlun multi-stage composite orogenic belt and important source of mineral resources; therefore how to analyze and underst and the geological background of the deposit is necessary.According to the regional tectonic evolution and deep geodynamics,sedimentary rock formation and the characteristics of temporal and spatial distribution of magmatic rocks and tectonic magmatism process and so on,in this article,the Qimantage regional geological background has been discussed; a number of views for further geological research and prospecting work have been brought forward; and some basic information of geology and specific ideas have been provided.
