中文摘要: 钦杭成矿带是我国东部一条极其重要的以钨、钼、铜、锡、铁为主的成矿带,安徽省泾县潘村地区属于该成矿带内。在潘村地区主要开展了地质填图和1︰1万土壤化探测量:初步查明区内构造、地层、岩浆岩分布及岩石学特征;圈定找矿靶区,化探异常划分出北部(Au、Ag)、中部(Au、Ag、Pb、Zn)、南部(Cu、Mo、Pb、Zn)三个异常靶区;在靶区内进行钻探验证,发现了矿(化)体;初步划分出蚀变带的垂向分带:浅部泥化带→中深部的绿泥石化带→深部的硅化、钾化、云英岩化带,矿化现象在浅部以金、银矿化为主,随着岩石蚀变的变化,矿化有铜、锌、铅、钼,云英岩化阶段,以铜钼矿化为主。对其赋存的地质特征进行客观研究与分析评价,提出在安徽省泾县潘村一带同样也具有钼多金属矿良好的成矿与找矿前景,其意义深远。
Abstract:Qinhang metallogenic belt is an extremely important metallogenic belt in eastern China , which is mainly composed of tungsten, molybdenum, copper, tin and iron in Qinhang metallogenic belt of eastern china, and Pancun in Jingxian County is belong to the metallogenic belt. The geological survey and 1:1 million soil geochemical Geological survey and 1:10 thousand soil geochemical survey were carried out in Pancun area:. the The characteristics of structures, strata the distribution of magmatic rocks and petrology iswere preliminary investigated in the area; , and the prospecting targets iswas delineated, Ggeochemical anomalies are were divided by the three main target that, including is the northern((Au、Ag)), central((Au、Ag、Pb、Zn)) and southern ((Cu、Mo、Pb、Zn))North; . Drilling is carried out in the target area and mineralized bodies are were discovered; the vertical zoning of alteration zones is was preliminary divided out: Mud zone in shallow place → Chlorite zone in the middle and deep position → Silicification, potassium and dolomitization zone in the deep, and Gold gold and silver mineralization is was the mainly mineralization phenomena in shallow place. With the change of rock alteration, the mineralization includes copper, zinc, lead and molybdenum, and Coppercopper-molybdenum mineralization is was dominated in the mica mineralization stage. The geological characteristics of its occurrence is was objective researched, analyzed and evaluated, and the results indicated it is pointed out that Pancun area the also has good prospects for mineralization and prospecting of molybdenum polymetallic deposits, which has providing far-reaching significance in Pancun area of Jingxian County in Anhui Province.
