江西九曲铜钨多金属矿床地质特征及成因探讨

摘要

九曲矿区地处南岭东西向构造带与罗霄北北东向断褶带的复合部位,定位于区域北东向安基山断裂北西盘,属三南(龙南、定南、全南)钨稀土矿集区组成部分.发育于在九曲花岗体内及接触带附近的近东西向-北西西向断裂破碎带为赋矿构造,已圈出铜钨多金属矿(化)体28条,铜钨铅锌银共生,佯生锡等有益组分,矿床成因与岩浆期后热液充填交代关系密切,属断裂破碎带蚀变岩-石英脉复合型铜钨多金属矿床.%Jiuqu mining area is in E-W-trending Nanling Tectonic Belt and NNE trending Luoxiao fault fold belt of composite parts.Located in the area of N-E Anjishan fracture N-W part,three South (Longnan,Dingnan,Quannan county) tungsten rare earth ore district part.Grow in the EW-NWW fracture zone near the of the granitic body and its contact zone is the ore bearing structure,circle copper tungsten polymetallic ore (chemical) body 28,copper,tungsten,lead and zinc,silver intergrowth,associated tin and other useful components.Ore genesis is closely related to post magmatic hydrothermal filling and metasomatism,belongs to fracture zone altered rock quartz vein complex type copper tungsten polymetallic deposit.
