| Abstract: | This study involves the integration of the multiple geological data sets for mineral exploration through spatial prediction models. The weight of evidence, as a data-driven approach for map combination, is used for gold potential mapping. To identify mineralized area in study area, geological, geophysical, and geochemical data sets are used. The data capture, map operations and spatial data analysis are carried out using the geographic information system (GIS). The results show that the weight of evidence method can integrate effectively various spatial data for mineral potential mapping and the final map delineated most favorable potential areas of mineralization for further investigation. |
