Abstract
The paper expatiates on the ore-forming geological background.It is believed that the Dongjiang ductile shear zone is a large scale ore controlling and bearing structure which is characterized by a three in one distribution regularity,namely the combination of structure rock zoning,alteration zoning and strength zoning of gold mineralization,by the analysis and summarizing of the geological characteristics of the gold deposit.It is pointed out that the stratiform-like gold orebody in ductile shear zone and vein type gold orebody in sharp tipping fracture (F1) has been discovered in the region and there are IP,aeromagnetic and gravity anomalies and geochemical anomalies in the presently barren east part,showing great prospective for ore hunting in the area.
