Abstract: Qingshuitang PbZn deposit in Hunan Province is located at the northeast side of ChenzhouShaoyang basement fault,PbZn orebodies are occurred with vein shapes in the NE trending and near SN trending faults of Cambrian and Ordovician.The PbZn orebodies are controlled by faults and stratigraphic position,and the orebodies with the regularities of equidistance disposition,vertical zonality and lateral trending to the south,a secondary sulfide enrichment belt is occurred near the area of evaluation 450~150 m.Based on the geological working results newly obtained in the mining area,the geological characteristics of the mining area and deposits,orebody spatial distribution regularity,deposit genesis and orecontrolling factor of the mining area are discussed in detail,it is show that the metallogenic process of the deposit can be described as following:the orebearing hydrothermal is moved upward along the basement faults to Qiyang mountain type tectonic fracture located in the surface,and the mineralization strata of Cambrian and Ordovician is leached and permeated from south to north,the hot brine mixture hydrothermal rich in mineral fluid is formed,and it is precipitated and enriched in the favorable metallogenic fracture belt (such as NE trending and near SN trending extensional tensoshear property fracture belts),so the mediumlow hydrothermal filling type PbZn sulfide deposit is formed.Based on the above analysis results,the prospecting model of the mining area related to geological characteristics,mineralization characteristics and comprehensive information characteristics is established,and the further study results indicated that the prospecting potential of PbZn deposit in the mining area is huge,besides that,the coexisting minerals or accompanying minerals such as Au, Ag, Cu, Cd and Sb with the characteristics of large〖HJ〗〖LM〗 scale and high grade can be found in the mining area by further conducting comprehensive prospecting work.
