Characteristics of Gold Deposits and its Sustainable Development in Tianshan Metallogenic Zone,Xinjiang

As an important gold metallogenic belt of China,Tianshan metallogenic belt in Xinjiang joints the central Asian polymetallic giant metallogenic belt in the west,connects the east Tianshan metalloogenic belt in the east with superior metallogenic condition and abundant mineral resource.At present,more than 30 gold deposits(points)are found in which develops gold deposits of three types as ductile shear zone,volcanic rocks and epimetamorphism clastic rock.Especially,the exploration of large scale Axi gold deposit and discovery of ultra-large scale Sawayaerdun gold deposit show fine prospecting potential of large and ultra-large gold deposit in metallogenic belt.With the rapid development of social economy,the demand of gold increases gradually beyond current resource reserves.Therefore,the authors suggest to intensifying the exploration and development of gold deposit,strengthening domestic and foreign cooperation as well as carrying on metallogenic rule research of gold deposit based on current gold deposit(point)to find large or ultra-large scale gold deposit and guarantee the resource supplies.In the meantime,lagging processing equipments are eliminated in order to increase the recovery rate of gold.
