Coal. petroleum, natural gas, gold, iron, magnesite, graphite, talc, molding sand, glass sand and some others account for large portion in reserves and yields of that in the whole country. The region faced also shortages of copper, molybdenum, oil shale, zirconium, tantalum, rare earth, and beryllium, although they have large reserves, but limited by economical and technical factors. Geological mapping and mineral exploration activities have been intensive. Only the north part of Daxinanling Mountains in the region leaves unexplored. GIS applications in mineral resource assessment in the region start not long. Databases for GIS applications are on the way of construction. Well - trained technical staff and expertise do not meet the demand. This article reviews the situation of mineral resources and GIS applications for mineral resource assessment in the region. Suggestions on multi - lateral cooperation and GIS training are also made.展开更多

Datasets used include Cu, Pb, Zn deposit points record, geological data, remote sensing imagery （Landsat TM5）. The mineral potential of the study area is assessed by means of GIS based geodata integration techniques for generating predictive maps. GIS predictive model for Cu, Pb, Zn potential was carried out in this study area （Weixi） using weight of evidence. The weights of evidence modeling techniques is the data driven method in which the spatial associations of the indicative geologic features with the known mineral occurrences in the area are quantified, and weights statistically assigned to the geologic features. The best predictive map generated by this method defines 24 % the area having potential for Cu, Pb, Zn mineralization further exploration work.展开更多
