摘要
缅甸佤邦糯巴矿区锡多金属矿是近年来在缅甸东部第二特区探明的中型锡矿,锡矿石品位较高并伴生铅锌等多种有色金属。矿床类型为典型高-中温度热液脉型矿床,矿体形体规模严格受区内近南北向和近东西向两组断裂构造控制。本文介绍了缅甸佤邦糯巴矿区锡多金属矿的地质特征,从区域地层、构造、围岩蚀变、矿石类型、控矿特征等方面对矿产进行综合分析。
The tin polymetallic deposit in the Nuoba ore district of Wa State,Myanmar,is a medium-size tin deposit discovered in the 2^(nd)Special Zone in eastern Myanmar.In the ore deposit,tin grade is relatively high and there exist such associated nonferrous metals as lead and zinc.The ore deposit is a typical high-medium temperature hydrothermal veinlike deposit.The ore bodies are strictly controlled by regional nearly NS-trending and nearly EW-trending faults.This paper describes geological characteristics of the tin deposit in Nuoba ore district,and makes an integrated analysis of this deposit in the aspects of regional strata,structure,wall rock alternation,ore types and ore-controlling factors.
