Abstract :
The method of weights of evidence is one of the most important data-driven method for mineral potential
mapping in GIS. In this method, considering the characteristics of known mineralized locations, new
mineralized areas can be prospected. In this study, the method of weights of evidence was used for
hydrothermal gold potential mapping in Torbat-e-Heydarieh area, east of Iran. As a relatively large number
of gold mineral occurrences (i.e., exactly 27 known gold mineralized locations) have been recognized in the
study area, the use of the weights of evidence method for prospecting new gold mineralized zones in the area
can be quite efficient. To determine probable gold mineralization zones in the form of a posteriori map of the
survey area, based on weights of evidence method, this study combined the results of the airborne
geophysical, geological, argillic, propillitic and iron oxide alteration, geochemical and structural data were.
Consequently, four major zones in this area were identified as high gold mineralization potential zones, in
which many vein and veinlet mineralization forms can be found.
