Abstract: The Xinfang Gold Deposit is a recently discovered medium-sized gold deposit,and the ore body mainly occurs within the ductile shear zone between the cover and basement of the Xinfang metamorphic core complex.It is strictly controlled by extensional detachment zones,with the predominant ore type being altered rock and the secondary quartz vein type.The deposit is currently being explored,and it has great potential for deep and peripheral mineralization.Through geological structural surveys,geophysical exploration,geochemical exploration,and drilling engineering,a three-dimensional geological structure model of the Xinfang Gold Deposit has been established for the first time.Through analysis of the three-dimensional spatial relationship between strata,magmatic rocks,structures,and ore bodies,as well as the study of mineralization laws,a 3D mineralization prediction model have been established,to provide scientific guidance for deep exploration in the next step.
