Abstract: Tuanshanzi area in Xingcheng City, Liaoning Province is tectonically located in the east section of the near E-W-trending Qinlong-Huludao fault, on the south margin of Jianchang intrusive rock body and in the Central south of the Bajiazi-Yangjiazhangzi polymetallic metallogenic province. Gold mineralization is controlled by the near E-W-trending fault. The metallogenesis belongs to cataclastic altered rock type, with characteristics of low grade and large amount of ore, which is the first discovery in western Liaoning. For further research on the ore-controlling structure and the distribution of gold mineralization in the area, the radiometric method is adopted in the prospecting and has achieved good results. Because it is simple and easy to be used, the method is significant in the searching of this type of gold deposits in the area and worth to popularize.
