The Late Palaeozoic volcanic rocks are well developed in Wangyangtai area of Balekkun, Xinjiang. NW- and NWW-trending tectonic fracture zones are extensively developed, and the mineralization and alteration of malachite and silicification are strong. In order to further guide the copper ore prospecting work in the area, the authors identified 16 single element anomalies such as Au, Ag, and Cu through the comprehensive processing of data obtained from the collection and test of samples from 1∶50,000 stream sediments in this area. According to the geochemical characteristics of various elements, the correlation of elements and the associated combination relationship in the evaluation area, the authors divided the elements into five types, i.e., chacophile-siderophile elements, low-temperature elements, sulfophile elements, high field strength elements and gold elements. According to the combination of abnormal elements and in combination with the geological background of metallogenesis, 14 comprehensive anomalies were identified, classified and ranked on the basis of the magnitude of their prospecting significance, and the important comprehensive anomalies with greater prospecting significance were evaluated and verified. Based on the results of anomaly verification, the rule of abnormal distribution and the geological background of mineralization, the HS-5 comprehensive anomaly was selected as the best copper prospecting target area, which provides an important basis for the geological prospecting work in the area in the future.
