Abstract:This area is located in the Liaodong rift metallogenic belt, the mineralization of Ag-Pb-Zn in Yinggedi is a long-term and multi-stage geologic process which functioned complexly. The deposit belongs to stratabound magmatic hydrothermal deposit, under the action of magmatic hydrothermal fluid, the minerals are transferred to the whole body and filled with the surrounding structural fractures. Based on the analysis of the metallogenic geological conditions in this area, it is considered that the ore-forming fluid is closely related to the activity of granodiorite. From No.Ⅳ to No.Ⅰ mineralized zone, silicification becomes weak, it is concluded that the rock body and concealed rock it is connected, and the preliminary delineation of the three metallogenic province, pointed out the direction for further prospecting work.
