摘要

The East Tianshan-Beishan Mountains have a great of mineral resources potential of copper, nickel and gold. The main types of discovered ore deposits are hydrothermal and magmatic ore deposit. In this paper, the weights of evidence model based on GIS is applied to mineral resource potential mapping, and 11 evidence map layers (fractures, ring structures, ore-bearing strata, lithologic diversity, Paleozoic mafic-ultramafic intrusion and intermediate-acidic intrusion, factors of geochemical anomalies, etc.) are extracted form the geological map, geophysical anomaly map, geochemical anomaly map and remote sensing interpretation map on the scale of 1:500 000. Then, 45 preferable ore-finding areas are delineated with the posterior probabilities, and the prospective metal reserves which include 600 Mt of Cu, 100 Mt of Ni and 2001 of Au are estimated. Finally, 5 good tracts for further mineral resource survey are suggested.
