| 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. |
