Knowledge-driven GIS modeling technique for gold exploration, Bulghah gold mine area, Saudi Arabia

摘要: Abstract This research aims to generate a favorability map for gold exploration at the Bulghah mine area using integration of geo-datasets within GIS environment. Spatial data analyses and different are carried out based on knowledge-driven weighting technique. The process involves scoring layers affecting mineralization study index overlay method PCI Geomatica Generation binary predictor maps lithology, lineaments, faults favorable contacts precede construction map. About 100 m buffer zones generated contacts, lineaments major layers. Internal is assigned each layer mineralization. scores faults, in constructed 50%, 25%, 10% 15%, respectively.
