摘要
本文应用卫星遥感图像,配合航片和实地调查,对区内地质构造进行了系统解译。建立了线性构造带状分布的空间格局,指出区内线性构造主要为北东和北西向二组,北北东、东西和南北向次之。空间上发育成带且带间平行等距;时间上各构造体系成生有序。基底构造主要为北东、北西和东西向三组,盖层的沉积建造、构造的成生演变、岩浆活动以及矿产分布都受其控制。圈定环形构造21个,与本区矿产分布关系十分密切。最后提出金铜(银)找矿远景区,并指出了重点勘查地段。
Landsat images and aerophotographs have been succesfully used along with field investigation to establish the linear structural pat-tern in this area. NE and NW trend structures are recognized as the main systems; NNE, E-W and S-N trend structures are less devel-oped. In space. these structures can be grouped in parallei zones with approximately equal distances in between; while in time, a clear suc-cession of development can be interpreted. The basement structures are mainly of NE. NW and EW trend. which cotrol the sedimentaryformations of the overlying strata & the evolution of the cover structures as well as the magmatic activities and mineral distribution inthe whole area. 21 circular structures at the conjunction regions of the linear structures are outlined as the most prospective with regardto polymetal mineralizalion.
