ABSTRACT: The Kalatereshm is an area in north of Iran which covers some part of
Torud magmatic belt. The area of this belt is about 2000 square kilometers and
most of the mines in this particular area are of Copper, lead and Zinc. The
Synthesis process is done by the Analysis Hierarchy Process (AHP) and Index
Overlay (IO) methods. Of previous studies on the area, various companies
providing Geological maps and in particular the company of Jiangxi providing
its own geochemical maps can be mentioned. The reasons for doing this research
and its innovation in Kalatereshm’s sheet can be justified as to be valuable
and the fact that we would be able to save in time and cost by doing so.
Previous case studies on this particular region lacked the necessary use of an
advanced software and method. The informational layers included geochemical layers
(the second and first ratings were given to Copper and Lead respectively by
weighting based on AHP method), geology layer (the fourth and second ratings
were given to Copper and Lead respectively by weighing based on AHP method), fault
layer (the first and fourth ratings were given to Copper and Lead respectively
by weighting based on AHP method), satellite imagery layer (the third rating
was given to both Copper and Lead by weighting based on AHP method) and the
more applicable areas for field exploration and detailed procedures of
exploration had been determined (the mentioned ratings were delineated by each
element’s respective weight in each layer and their importance in the Synthesis
of informational layers).
