class targets, and field observations proves the efficiency

of this method. This method can be used in the similar

geological and metallogenetic locations in north-west-

wards and south-eastward s of the study area in Iran.

4. Conclusions

Analysis and investigation of first class prospect areas

after field checking prove that these areas have charac-

teristics as follows:

They are located mainly in the intermediate Oligo-

cene_Miocene intrusive bodies, or Eocene volcanic-

sedimentary complex.

The porphyry copper mineralization is related to re-

gional scale faults (length more than 10 km). The

most important trends for mineralization are N-S,

NE-SW, E-W, and NW-SE respectively.

Hydrothermal alteration is extensive and typically

zoned on a deposit scale. The main alteration types

are:

o Advanced argillic alteration

o Argillic alteration

o Phyllic alteration

Normally in porphyry copper mineralization, copper

and molybdenum geochemical anomalies in center

part, and lead, zinc, silver, bismuth, and magnesium

geochemical anomalies in outer part of alteration ha-

loes can be detected.

Airborne geophysics data can be very definitive in

locating porphyry copper deposits related to hydro-

thermal systems. However no unique technique suf-

fices, it is necessary to utilize two or three techniques

to maximize the probability of finding new deposits.
