摘要
Abstract
Based on our studies of magmatic rocks,especially granitoids widespreadin g in west Kunlun Mts., combining with the geological characteristics of regional tectonics and sedimentary formation,the geologic-tectonic evolution has been r estored in this paper,and then the metallogenic-depositional environments and me tallogenic-geologic features were studied. The results indicate that the west Ku nlun Mts., undergoing the complicated geologic-tectonic evolution,is a compound orogenic belt consisting seperately of the Caledonian,Hercynian and early Yansha nian orogenic belt from north to South. There exist 5 metallogenic-depositional envi ronments,i.e., ocean ridge(ophiolite) metallogenic-depositional environments(Cyp rus type Cu-pyritic deposit,podiform Cr-Ni deposit),passive continental margin m etallogenic-depositional environments (MVT Pb-Zn deposit,Sedex type Pb-Cu deposi t), volcanic arc metallogenic-depositional environments (porphyry type Cu deposi t,Kuroko type Cu-Pb-Zn deposit,skarn type Cu-Pb-Zn-polymetal deposit),back-arc b asin metallogenic-depositional environments (seafloor volcanic erup tion-sedimentary type Fe-Cu deposit, gas-liquid filling type Cu-Au-Fe deposit),s yn-collision metallogenic-depositional environments (pegmatite type rare-metald eposit,pegmatite type polymetal-Ag deposit).关键词
