摘　　要：金寨县仓房—洪家大山调查区属于桐柏—大别山金及多金属找矿重点片的东段,是安徽省重要金(银)矿产区和成矿远景区之一,所处大地构造位置成矿地质条件优越,区域上已发现如沙坪沟钼矿、汞洞冲铅锌矿等一批钼及金银铅锌等多金属矿床(点),显示了良好的找矿潜力。通过在区内开展物探、化探、钻探等多种技术手段,圈定了8个集中分布于八斗湾—仓房—大银山地区的银铅锌组合异常(Hs-1—Hs-8),确定了区内找矿矿种和找矿区域。结合以往研究成果,对矿床成因和找矿标志进行了进一步综合分析,为区内寻求更大找矿突破指明了方向。The investigation area of Cangfang-Hongjiadashan in Jinzhai County belongs to the eastern section of Tongbai-Dabie gold and polymetallic prospecting area,which is one of the important gold(silver)mineral production areas and prospective mineralization areas in our province,and is located in a geotectonic position with superior geological conditions for mineralization.A number of molybdenum and gold-silver-lead-zinc polymetallic deposits(points)such as Shapinggou molybdenum mine and mercury-dong punch lead-zinc mine have been found in the area,showing good potential for mineralization.Through various technical means such as physical,chemical and drilling exploration in the area,eight silver-lead-zinc combination anomalies(Hs-1 to Hs-8)concentrated in the Badouwan-Cangfang-Dayinshan area have been identified,and the mineral species and mineral search area in the area have been determined.Combined with the previous research results,a comprehensive analysis of the genesis of the deposits and the mineralization signatures was further carried out,which pointed out the specific direction for seeking a greater breakthrough in the mineralization search in the area.
