摘要
Abstract
The Namuqin gold﹣polymetallic deposit is located in the western section of Bangonghu﹣Nujiang metallogenic belt in Tibet,with regional mineralization dominated by copper,gold and iron. The study indicates that the copper orebodies in Namuqin deposit are controlled by skarn in the contact zone between the Middle Permian Xiala Formation and Early Cretaceous acid﹣intermediate intrusive rocks,while the gold orebodies are mainly controlled by the near E﹣W﹣trending fault. The metallogenesis of copper and gold are skarn type and structural altered rock type respectively,with the ore﹣forming age of Early Cretaceous. The deep of Nos. I,II and III orebodies and west of No. II copper orebody in the orefield still have great prospecting potential. Study shows that the Namuqin deposit shares similar geological background and metallogenic characteristics with Garqiong deposit in the region,but also with special features.关键词
