It is the most representative in the area of lead and zinc- copper - molybdenum - silver - gold clusters. According to the geological and other main characteristics of the mineralization in the study area, mainly polymetallic ore deposit is divided into two metallogenic system: The late Paleozoic - Mesozoic porphyry - hydrothermal mineralization system and Mesozoic tectonic hydrothermal metallogenic system. The metallogenic series is further discussed about types of main minerals, geological characteristics, origin, etc and concluded the ore-forming regularity. ①From the ore formation, surrounding rock of ore deposit are mainly Permian, Jurassic acidic volcanic rocks and volcanic rocks.②From the tectonic control mine, the collapse anticline axis belt, north east and north west fault interchange is the good place of ore.③From the metallogenic epoch, period of indosinian and yanshanian is an important metallogenic stages.④From the prospecting type, there are the main output and the volcano - intrusive complex related skarn type, porphyry type - epithermal type polymetallic deposit,
