摘　　要：湖南省茶陵县婆婆仙锡钨矿床规模达到中型,主要矿床类型为矽卡岩型和构造蚀变带型-矽卡岩复合型,其资源储量已基本查清,继续找矿前景有限。为了取得新一轮找矿突破,解决找矿瓶颈,本文深入分析了矿床地质特征,总结了矿床类型和主要矿体特征。通过矿床成因和成矿作用的剖析,建立了成矿模式。总结找矿标志,提出了找矿方向,指出婆婆仙矿床内的断裂构造蚀变岩型锡钨矿体和断裂充填石英脉型锡钨矿体还有较好的找矿前景,特别是岩体(云母)型锂铷矿床具有大中型矿床的找矿前景。The Popoxian tin-tungsten deposit is of medium scale,with the primary deposit types being skarntype and structural alteration zone-skarn composite-type.Its resource reserves have been basically determined,and the prospects for further exploration are limited.In order to achieve a breakthrough in exploration and overcome the exploration bottleneck,this paper conducts an in-depth analysis of the geological characteristics of the deposit in the area and summarizes the deposit types and main features of ore body.By analysing the ore genesis and mineralization,a mineralization model is established.This paper summarizes exploration indicators,presents prospecting directions,and points out that Popoxian Mine Area contains promising prospects for fault tectonically altered rock-type tin-tungsten deposits and fault-filled quartz vein-type tin-tungsten deposits,especially the large and medium-sized ore deposits in the form of rock-mass mica type lithium-rubidium ore deposits have promising prospects.
