| 摘 要： | 针对西昆仑恰尔隆、大同一带,在对区域地质背景进行分析的基础上,采用卫星遥感图像ETM对西昆仑地区的遥感影像线性特征和环形特征进行了解译,得出该区断裂发育且分期次,区内环形构造说明该区岩浆活动剧烈;划分出南北向和北西向为主的线性构造格局,其中南北向断裂晚于北西向断裂,并控制了环形构造的展布;认为南北向和北西向线性构造交汇并与环形构造叠加的部位是有利的成矿区段,类比已知矿区,圈定出4个找矿远景区。

| Abstract: | Based on analyzing the background of area geology and using ETM remote sensing image,we have detailedly interpreted the features of linear and annular structures in Kayizi,Datong region of the western Kunlun.The result shows that the fault developed well and they formed in different stages in this region.Moreover,their annular structures indicate tensive magmatic activities in the study region.Integrated with all data,it is obvious that the linear structures are dominated by SN an NW trending faults,and the SN fault develop later than NW ones and control the developing and distributing of annular structure.Hence,it is likely that the overlapped area of SN linear fault,NW liner fault and annular structures is potential for mineralization.By further comparison with known ore districts,four prospecting target region are outlined. |
