Abstarct: Shotor-Kuh mextamorphic - igneous complex is located in 80 km south of East Shahrood, this complex is part of the Iran baxsement late Neoproterozoic mextamorphic terrian (540 to 600 million years ago) and includs mextamorphic - igneous rocks such as mextapelite (micaschists and gneisses), mextabasite (amphibolite), mextacarbonate (limestone and dolomite marbles), mextapsammites and gabbro, olivine gabbro and diorite. This is cut by a small number of Middle Jurassic diabasic dykes. Also part of them is covered by the Late Triassic - Lower Jurassic sedimentary- clastic sequence. Investigation of magnetic parameters high-grade mextapelitic and mextabasitic rocks during processing of Migmatization and granitization of mextamorphic- igneous complex between Gorgabi - Jamil (South East Shahrood) show that gneisses have mean magnetic susceptibility (Km) 326 μSI and the interval between Km changes in these rocks is 136 μSI to 670 μSI. The important magnetic behavior carriers are Garnet and biotite and minor amount opq minerals (ilmenite or magnetite) in gneisses. Modified magnetic anisotropy (Pj) diverse between 8.0 to 18.7 percent in gneiss. The shape parameter of this rocks is between 0.44 until 0.97 and most of magnetic ellipsoids are oblate. In granitic aplites results from partial melting gneisses minerals of magnetic behavior carriers are lack and consequently their mean magnetic susceptibility value (with an average 107 μSI) compared to other rock groups is very low. Because of intense deformation and mylonitization this rocks, the amount percent of modified magnetic anisotropy (Pj) This group is very high and reaches about 44 percent. The mean magnetic susceptibility in amphibolites and garnet amphibolite is 550 μSI and also the amount Km varies between 220 μSI to 1200 μSI. Iron and magnesium bearing minerals such as green hornblende, garnet and biotite and in particular iron oxides such as magnetite and titanomagnetite magnetic behavior carriers are in these rocks. Modified anisotropy of magnetic susceptibility (Pj) vary between 1.1 to 14.3 % in the rocks. Their Shape parameter majority measured sample is positive and its dominant magnetic elliptical-shaped is oblate. Plagiogranites or tonalites are the results from of mextamorphic differentiation or partial melting of amphibolite and garnet amphibolite also have low mean magnetic susceptibility 100 μSI. Percent of mean magnetic anisotropy is 7% and the shape parameter is positive. generally, this study shows that the values of mean magnetic susceptibility is a function of the type and frequency of the magnetic behavior carrier minerals. In the studied rocks biotite, garnet, hornblende, green, opq minerals (magnetite, Titano-magnetite and ilmenite) are magnetic behavior important carriers. On the other hand the numerical values of the shape parameter, the percentage of magnetic anisotropy and intensity of deformation have direct relationship and ascending. In the study area magnetic foliation are low steep often and magnetic lineations are arranged mainly to southeast. These results can be confirmed by field evidence and is compatible with the large-scale dome structure of Shotor-Kuh mextamorphic- igneous complex as a mextamorphic Core Copmlex. Although local factors as shear zones are involved in the creation of structural elements and cause local changes in the structural elements characteristics. But it seems that a large-scale deformation event incident affected the entire area and exposed rocks. So that apart from younger rocks, such as Middle Jurassic low-grade mextamorphic rocks and a few of diabasic dykes cuting them (middle Jurassic), mextamorphic rocks with the sedimentary or igneous protolith show clear evidence of foliation, liniation and mylonitization. Although this evidence may also be associated with varying degrees of intensity and infirmity.
