摘　　要：围绕湘南千里山岩体钨锡多金属矿产资源集中产出,柿竹园钨锡多金属超大型矿床便是典型范例,被誉为“世界有色金属博物馆”。该矿床的形成和产出与其特殊的构造环境、成矿条件等密切相关,更是多成矿因素相互叠加与耦合作用的结果。泥盆系中统棋梓桥组是钨锡多金属成矿的有利围岩,泥盆系上统佘田桥组是钨锡多金属矿床的主要赋矿层位,碳酸盐岩地层是形成矽卡岩型矿化的重要物质基础。矿区内接触带型构造控制着云英岩型矿床、矽卡岩型矿床以及大理岩型多金属矿床的产出,而断裂是脉状铅锌矿、脉状锡石硫化物型矿床以及石英脉型钨矿的控矿构造。岩体接触带的特殊形态与特殊部位,常常有利于矽卡岩型多金属矿床的发育。Tungsten-tin polymetallic mineral resources are abundant around the Qianlishan granite mass in southern Hunan,among which Shizhuyuan tungsten-tin polymetallic superlarge deposit is a typical example that is known as the“world nonferrous metals museum”.The formation and occurrence of the deposit is closely related to its special tectonic environment and metallogenic conditions,and it is also the result of the superposition and coupling of multiple metallogenic factors.The Qiziqiao Formation of middle Devonian is the favorable wall rock for W-Sn polymetallic mineralization,and the Shetianqiao Formation of upper Devonian is the main ore-bearing strata of the tungsten-tin polymetallic deposit,yet the carbonate strata is the important material basis for the formation of skarn mineralization.The contacting zone structure in the mining area controls the occurrence of greisen type ore,skarn type ore and marble type polymetallic ore,yet the faults are ore-controlling structures of vein lead-zincore,vein cassiterite-sulfide ore and quartz vein tungsten ore.The special shape and location of rock mass contacting zone is often favorable for the development of skarn polymetallic deposits.
