The Mineralization Of Gold Deposits Related To Shear Zone In Tianger Gold Deposits Belt, Xinjiang

The Tianger gold deposits belt located at south of Tianger mountain peak, and north of Tianshan watershed, in Xinjiang. And it is NWW-SEE trending located at the fault zone of northern Margin of the central Tianshan. In the Tianger gold deposits belt, there are the Saridala gold deposit, the Bingfeng gold deposit, the Wangfeng gold deposit and the Asuwo gold deposit and a series of gold occurrences. The study has showed that all the gold deposits in the Tianger gold deposits belt are the gold deposits related to shear zone. And there are some differences in geology and geochemistry between the gold deposits in different depths. But it needs to do some further study about the process and mechanism of the differences formation.This study is supported by the National Key Technologies R&D projects during the Tenth Five-year plan "The evaluation of Saridala gold deposit and its peripheral target area", and the National Key Technologies R&D projects during the eleventh five-year plan "The ore deposit location prediction and the technology & application of prospecting target evaluation in Tianger- Yilianhabierga gold deposit belt, Western Tianshan". And the systemic researches on the characteristics, the source of metallogenic material, the process of metallogenic material evolution and the process and style of mineralization have been carried out by means of geology, geochemistry and fluid inclusions. So these points of view are put forward thereinafter.1. There are some new datas about the source of metallogenic material have be found in this research. The geology and geochemistry characteristics of the Wangfeng gold deposit have close relationship with the Saredala's, which indicate that they have similar source. All the characteristics of two deposits show their metallogenic material has multiple sources, but mainly come from the deep source.2. By further study, the zoning of mineralization and alteration is made clear in this research. Combined studying of petrography and mineralography show that the all ore body in the Tianger gold deposits belt may have similar alteration zoning, which are concentric semi-lenticular. And through the center to the outer, there are albitization zone, sericitization zone and silicified zone.3. The mass transfer between the different alteration zones has been find out preliminarily. The study of tectonic geochemistry show that there is mass transfer between the different alteration zones, such as the material transferred into the silicified zone may come from albitization zone.4. The metallogenic mechanism of the gold deposits in the Tianger gold deposits belt is combined action between the ore-forming fluid react with the rock and the mixing of fluid with different source. But in different depths different metallogenic mechanism works mainly.5. The eastern Tianger gold deposits belt has good Prospect of deep exploration.
