Mineral prospectivity mapping and geochemical anomalies identification based on multifractal modeling in the Taerbahatai-Sawuer area, Xinjiang

The Taerbahatai-Sawuer area is located within the northwest of Xinjiang, China, in which some copper and gold deposits have been discovered shows a very high mineral potential in this area. Prospectivity mapping is often used for combining the exploration criteria and predicting mineral potential area. This paper firstly uses the singularity mapping based on multifractal theory to identify the geochemical anomalies, and then by analyzing the ore-forming conditions in detail, uses the relationship between geochemical anomaly, structure, magmatite rock, stratum and mineralization to build the prospectivity model for Cu and Au mineralization of Taerbahatai-Sawuer area; furthermore, based on the recent prospecting results, the weights of evidence modelling has been used for the Cu-Au prospectivity mapping by taking the known Cu-Au deposits and occurrences as the mineralization fact. The results shows a lot of high mineral potential area in Taerbahatai-Sawuer area, and some new area of high prospectivity can be used as new targets for the further exploration.
