Abstract: The Qingchengzi ore field,located in the East Liaoning rift,is known as a concentrating area for nonferrous and precious metallic mineralization.Tectonically,the deposits occur in the metamorphic rocks of Peleoproterozoic Liaohe group,on the south limb of the Caohekou synclinorium,on Yingkou peleo-uplift,in the east section of the north margin of North China platform.Based on the studies on the geochemical characteristics and geochemical anomalies of elements in the Qingchengzi ore field,the origin of the ore deposits belongs to the type of metagenetic magmatic hydrothermal reformatiom.The contents of the ore-forming elements of Pb,Mo,As and Cd are high in the ore field,while Cu,Hg,V,Ti and Mn are lower.The magmatic rock bodies in the ore field are rich in Pb,Zn,Ag,Sb,B and Cd,but poor in Cu,V,Ti and Mn.The distribution of the elements is characterized by horizontal and vertical zonations.
