摘　　要：湖南省溆浦县龙王江金锑矿区位于湘西雪峰弧形构造带中断西南侧,是华南褶皱系与扬子准地台结合部的南东侧,主要为龙鼻桥-陶金坪复式背斜及其边缘。在查阅前人资料的基础上,从地层和矿区构造两方面研究了矿区的成矿地质条件;矿区主要呈上金下锑分层的分布,矿石主要为辉锑矿、黄铁矿、毒砂,矿脉主要为已知的10条,其中有4条为主要矿脉,矿床主要为断裂构造控矿。通过对矿区矿脉特征和矿石特征的研究,展示了矿区的矿床特征;同时从构造、地层岩性和岩浆活动等方面分析了矿区的控矿因素、分布特征和找矿标志。在上述研究的基础上总结了龙王江金锑矿的成矿规律,对矿山找矿远景提出了建议。Located in Longwangjiang,Xupu County,Hunan Province,gold-antimony ore district is on the disconnected southwest side of arcuate tectonic belt of snow peak in western Hunan Province,on the southeast side of the joint between south China fold system and Yantze Platform,along Longbiqiao-Taojinping complex anticline and its edge. Based on previous data,this paper studies geological conditions for the formation of ore district from two aspects such as stratum and structure of ore district. The ore district is distributed in layered way,namely,gold in upper layers and antimony in lower layers. Ores mainly include gray antimony,pyrite and arsenopyrite. There are ten known ore veins,four of which are major ones. Main ore deposits are fracture tectonics ore-controlling ones.Through studying the characteristics of vein and ore in ore area,the paper reveals the characteristics of ore deposit in the ore area. Meanwhile,it analyzes the ore-controlling factors,distribution characteristics and ore-searching evidences in the ore area from aspects like structure,stratum lithology and magma activity. On the basis of above research,the paper summarizes the formation regularity of gold-antimony ore in Longwangjiang and makes proposals for future ore-searching at the mine.
