Özet:

 


The aim of this research is to compare index overlay and TOPSIS (based on AHP weight) for predictive
Skarn potential map. In this paper, for Calcic Iron Skarn mineralization, criteria and subcriteria introduced
and ranked for generating mineral prospectivity map. The values of fi nal prospecting maps for Skarn
deposit by index overlay and TOPSIS methods was specifi ed by dividing the prospectivity values into
10 classes. For better comparison, values assign to classes base on their priority in mineral exploration.
The comparative analyses of index overlay and TOPSIS integration methods, has been performed by
selecting four GCPs for fi eld checking. Field observation in GCP 1, 2 and 3, confi rmed Iron mineralization
in the contact of intrusive bodies with sedimentary units, where the contact metamorphism was obvious
but there is no observable mineralization in GCP4. Although high magnetic is distinct in mentioned
GCP. Based on the fi eld checking in Sarvian area, the TOPSIS method has more accuracy compared
to index overlay approach. Therefore, the TOPSIS method recommends for Calcic Iron Skarn Mineral
Prospectivity Mapping in Sarvian and adjacent area.
