| Abstract: | The Qingchengzi ore field,located i n the East Liaoning rift,is known as a concentrating area for nonferrous and precious metallic mineralization.Tectonically,the deposits occu r in the metamorphic rocks of Peleopr oterozoic Liaohe group,on the south limb of the Caohekou synclinorium,on Yingkou p eleo-uplift,in the east section of t he north margin of North China platform.Base d on the studies on the geochemical ch aracteristics and geochemical anom alies of elements in the Qingchengzi ore field ,the origin of the ore deposits belo ngs to the type of metagenetic magmatic hy-drothermal reformatiom.The conten ts 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 magm atic rock bodies in the ore field are r ich in Pb,Zn,Ag,Sb,B and Cd,but poor in Cu,V,Ti and Mn.The distribution o f the elements is characterized by horizontal and vertical zonations. |
