ABSTRACT: Urumieh-Dokhtar Magmatic Arc (UDMA) is
known as a belt with copper and some other metal deposits. The study
area is a part of Jebal Barez Mountains located in southeastern of the belt in
Iran. Two types of deposits are known in the belt. Semicircular patterns of
altered rocks associated with Eocene to Miocene intrusive rocks are known as porphyry
copper deposits and linear altered rock patterns associated with extensive
faults or dikes indicate potential epithermal or polymetalic vein deposits. In
order to clarify the relationship between faults and mineralization, at first alteration
zones have been mapped by using remote sensing methods. Then by geological maps
and satellites images, most of faults have been revealed and mapped. Based on
calculated photolineament factors in smaller districts, a contouring map was drawn.
Although assumed faults are pathways for hydrothermal fluid, in regional scale
because of difference of geometry, kinematic and timing of faults, all of them
have not the same value for mineralization but insist on density of faults and
value of photolineament factors can be more useful for preliminary exploration
of copper minerals.
