Abstract:
The Yangjiazhuang Gold Polymetallic Deposit is located in the gold polymetallic ductile shear metallogenic belt between the two regional structures of the North Qinling Mountains.For now,12 gold polymetallic ore bodies have been delineated.They are stratiform,veins and lens occurring in fractured alteration zones.Comprehensive analysis shows that ore bodies are controlled by multiple factors such as strata,structures and magmatic rocks.The host rocks are metamorphic tuff and carbonaceous slate of the Erlangping Group Damiao Formation.The NWW-trending faults are the main orehosting structures.The secondphase granite of Yanshanian period provided the heat source for the ore-forming minerals activation,migration and enrichment.
