The Jiama-Qulong ore concentration area,Tibet,124km long and69km wide,is located in the east-central part of the Mid-Late Jurassic-Paleogene Gangdise continental-margin volcanic-magma arc.Through recent geological survey,mineral exploration and ore deposit study,the authors found several ore concentration areas in the Gangdise continental-margin volcanic-magma arc,of which the Jiama-Qulong ore concentration area is one of the important copper polymetallic ore concentration areas in the arc.The deposits of this area are represented by the large Jiama-Qulong copper polymetallic ore deposit which is being ex ploited.In addition,they also found a number of very promising deposits and mineralization oc-currences such as Oulong South,Oulong North,Dirima ,Songduoxiong,Lakang'e and Xiangbeis han.They are characterized by unique mineralization types and a variety of genetic types,suggesting that they are products of different stages of evolution of the Gangdise continental-margin volcanic-magma arc.These dif ferent types of deposit are concentrated in a certain areal extent and have primarily shown and formed an important ore concentration area with great ore potential and a certain ore prospect in the Gangdise continental-margin volcanic-magma arc.The authors believe that through further work this area is expect-ed to become another nonferrous mineral resource base in western China.
