    Abstract
  • The Kalamaili gold belt in East Junggar is one of the important gold metallogenic belts in Xinjiang. Relevant scholars have carried out a large number of production and scientific research work, and achieved fruitful results in ore-finding, and accumulated a lot of research. In recent years, with the rise of deep exploration and the maturity of mineralization prediction methods, qualitative research has become an inevitable choice. Based on the previous comprehensive research, this research establishes a database platform based on ArcGis platform, and uses the evidence weight method to carry out quantitative evaluation of fault and gold mineralization space. The results show that the fault distance and density are important evidence weight factors. When the fault distance is in the range of 0~1500 m, the mineralization is the strongest. As the distance increases, the mineralization becomes weaker; when the fault density is between 0.26 and 0.66, it is a medium-high favorable ore-forming area. The research results are of great significance for the prospecting work in the deep and peripheral areas of the Kalamaili gold belt.
