| 近年来湖南祁阳地区在热液裂控型铅锌矿床勘查中取得了重大突破,先后探明有留书塘、清水塘、石桥铺、戴家岭、草鱼塘等多个大中小型铅锌矿床,这些矿床主要分布在岩体外接触断裂破碎带及板岩地层裂隙带中。前人在该地区开展勘查工作的过程中,均是对单个已发现的矿床进行单独勘查,没有将各个矿床关联成一个整体进行系统分析研究。文章通过对留书塘、清水塘、戴家岭3个典型铅锌矿床地质特征、成矿条件等进行分析研究,系统解剖了湖南祁阳地区铅锌矿床特征,总结了该地区铅锌矿床成矿规律,认为该地区铅锌矿成矿条件优越,具有很好的找矿前景。首次提出了该地区硫、铅等成矿物质主要来源于深部岩浆热液,部分来自地层的概念,并将该地区铅锌矿体按赋存空间及成矿类型分为3类:第一类为断裂构造破碎带型铅锌矿体；第二类为裂隙充填型铅锌矿体；第三类为推测的接触交代矽卡岩型铅锌矿体。 |

| In recent years, a major breakthrough in the exploration of magma hydrothermal fault controlled lead-zinc deposits in Qiyang area,Hunan Province. Liushutang, Qingshuitang, Shiqiaopu, Daijialing, Caoyutang and many other large, medium and small lead-zinc deposits one after another be found in the exploration. These mineral deposit mainly distributed in fracture zone and slate stratum fissure zone with rock mass external contact. Predecessors in the process of conducting exploration work in the area, All are prospecting works be aimed at discovered alone lead-zinc deposits, Systematic analysis studies were not carried out by associating individual lead-zinc deposits into one. This paper analyzes the geological characteristics and metallogenic conditions of three typical lead-zinc deposits in Liushutang, Qingshuitang and Daijialing, systematic dissection of the characteristics of lead-zinc deposits in the qiyang area, Hunan. The metallogenic regularity of lead-zinc deposits in this area is summarized, It is considered that the lead-zinc ore deposit conditions in this area are superior. Has a good prospects in lead-zinc deposits prospecting.It is first proposed that the ore-forming materials such as sulfur and lead in the region are mainly derived from deep magmatic hydrothermal fluids, partly from the stratum.The Pb-Zn orebody in the area are divided into three categories according to the storage space and metallogenic types:The first type lead-zinc ore bodies controlled by faults; The second type of lead-zinc ore body occur in stratum fissure;The third type is the presumed contact metasomatism skarn type lead-zinc ore body. It can provide reference for the next prospecting direction i in Qiyang area, Hunan Province. |
