摘　　要：锡田钨锡多金属矿床是国土资源大调查以来在南岭地区发现的又一大型矿床。矿床产于锡田复式花岗岩体内外接触带及岩体内部,其形成与燕山早期花岗岩关系密切。岩体接触面及断裂构造的控矿作用明显。矿床类型主要为矽卡岩型,其次为破碎带蚀变岩型和云英岩脉型等。论文通过成矿地质条件、矿床地质特征的综合分析,结合近几年的找矿实践,提出了该区下一步的找矿方向主要集中在西部的垄上-狮子岩、东部的碉堡山-黄沙冲一带及地表云英岩脉带发育地段,外围找矿方向分布在南西部的花里泉一带。Geological Characteristics and Exploration Potential of the Xitian W-Sn Polymetallic deposit, Hunan Province The Xitian W-Sn poly-metallic deposit is found during the mineral resources survey program launched by the Ministry of Land and Resources of P. R. C, it is another major discovery after the Qitianling Sn deposit in the Nanling mineralization belt. The orebodies are hosted within the Xitian granite complex and also the inner and outer contact zones, and the mineralization are clearly controlled by contact zones and faults. The main deposit types include the skarn, structure-controlled alteration rock and greisen type. The geological setting of the surrounding areas is favorable for mineralization and the aera has great potential for W-Sn ore prospecting.
