Title: GEOLOGY AND GENESIS OF YANJIAGOU Au DEPOSIT IN HUAILAI COUNTY,HEBEI PROVINCE
Abstract: Eight ore bodies have been found in the Yanjiagou gold deposit through comprehensive geological methods including geological survey and drilling.Ore bodies,most of them are blind,occur in the inner part of quartz monzonitic porphyry or at contact structural alteration zones with dolomite. Quartz vein type Au and Cu mineralization occurs in quartz monzonitic porphyry, and stockwork altered rock type Au,Pb and Zn and structural altered rock Ag mineralization individually occur in the inside and outside contacting zones.Main ore bodies are controlled by quartz monzonitic porphyry,subsidiary structures and fissures.Superimposition and reformation by hydrothermal fluids of post-magma made mineralization process complex.
