The gold-silver complex ore field of Qingchengzi is located in Liaohe group of Liaodong rift. The gold-silver ore bodies mainly lie in Dashiqiao group and Gaixian group. which provides ore-forming materials for the mineralization. For taking place multi-period and multi-stage magmatic activities, the ore-forming materials in the formation had had dyna- mothermal metamorphism for a long time and enriched and formed ore bodies after magmatism in Indo-Chinese and Yan- shan epoch. The ore bodies are controlled by stratigraphic formation and stored in the interformational faults and schistosity belts. Silicalite is the most important indicator for searching them. Although the Pb-Zn and the gold-silver deposits are the same series of mineralized products, their positions are different, resulting from the differences of elements nature and mineralized conditions. The gold silver deposits belong to strata-bound and hysterogeneticmesothermal-epithermal de- posit. The gold-silver complex ore field of Qingchengzi is located in Liaohe group of Liaodong rift.
