Abstract: Background the Paoshouyingzi area in Dandong,Liaoning Province,is located in the East Asia section of the second ring outside the centralwestern Pacific Gold Ring in the global gold metallogenic belt,and the east section of the Fengcheng Arch in Kuandian Platform of the sinokorean paraplatform and Jiaotailong platform,the southwest part of the Yalu River metallogenic belt lies across the river from the famous Pingbei gold concentration area of the Democratic People's Republic of Korea in the East.Aim to point out the direction of ore prospecting.In order to determine the favorable position of ore prospecting through the study of metallogenic law in this area.Methods the geological characteristics,source of oreforming materials and physical chemistry environment of Liaoning Province were studied by the Geological Survey Project of Liaoning Province.The results show that the oreforming Materials of gold deposits in the area are mainly from deep source areas,and the oreforming hydrothermal solution is mainly from magmatic water.Conclusion the geological evolution history and metallogenic geological background of the area are very similar to that of the area,and it has the geological potential to form large gold deposits.

Key words: Metallogenic geological characteristics,Metallogenic regularity,Prospecting direction
