The ore control law and prospecting suggestions of the shear zone in the Jinchangyu gold deposit in eastern Hebei province
The Jinchangyu gold deposit in eastern Hebei is a typical deposit controlled by tectonic action.The gold deposit mainly occurs in the strong deformation zone within the NNE trending brittle ductile schistosity zone,and the directly controlling structure is the NNE trending Yanshanian brittle fault structure superimposed on the strong deformation zone.On the basis of detailed field investigation,this article carried out structural staging matching and established a lens body control ore model of weak deformation domain controlling rock+strong deformation zone hosting ore.Combining with the occurrence and mineralization enrichment laws of ore bodies,the exploration directions of deep ductile brittle schistosity and secondary parallel structures on both sides were proposed.
