This area has been located in a scene ETM No. 164-37 and ASTER linear band prediction satellite image No. AST-L1A:002:ASTL1A 0108220733380109011021. Such measured images in different band combinations will be used for extracting of geological structures and types of alterations (iron oxide, Argillite and Carbonate) and for detecting different stones and minerals of the ground, a spectrum range of 1.5 to 2.5 μ is very important.This range includes short to average IR range covering six linear band predictions (SWTR bands). On the other side, to use spectral reflectance curves of such minerals in USGSENVI spectral library for spectral analysis, it is necessary to resample the curves to the spectral range of ASTER. Linear Band Prediction methods, LS-Fit, Matched Filtering and BandRATIO used of ASTER images for all Minerals and iron alterations and for iron oxides there were also used visual interpretations and ETM images were used in band combination of RGB:531. Considering the petrological and geological situation of studied area (Scale 1:25000 of Kamoo), the type of Alteration and its index minerals detailed as below; Alteration of iron (Gotit, Hematit and Jarosit and Limotit), alteration of Argilic (Kaolinite, Motmorilonit, Ilite and Haloysite) and carbonate (Calcite and Dolomite) have been considered. Alterations present in remote sensing studies are in conformity with field and results obtained fromtypes of analysis conducted.

Haji Abad granitoid pluton (~90Km²) is located in 135 Km southwest of Tehran, 7 Km south of Boin Zahra city (Fig.1).This pluton with approximate age 39.2(±3.2)Ma [4] emplaced in central of Uromieh – Dokhtar zone rocks. This pluton has a compositional rang of granitoid rocks include syenogranite, monzogranite, granodiorite and granophyr. Under study pluton in view of magmatic series is calk-alkaline, medium to high K and in view of alumina saturation index is meta-alumine nature. Field, geology, petrography and geochemical study indicate that these granitoids are High temperature magnetite I-type or Cordiller I- type granitoids.
