On the basis of petrographic observations and electron microprobe analyses data set on major and minor minerals from ultramafic- mafic rock suite with komatiitic to picritic - tholeiitic affinity, East of Fariman, we have investigated some of the petrological features of their parental magmas and condition of minerals crystallization. Major minerals in ultramafic rocks show various disequilibrium textures, including elongated hopper olivines with sharp tips, and spray to acicular, skeletal and hopper elongated pyroxenes, while in mafic rocks disequilibrium textures are dendritic pyroxene - plagioclase intergrowth. Such textures must have been produced by rapid growth of crystals due to undercooling of a previously superheated melt. High Fo contents of olivines is necessary the equilibrium of these crystals in a hot melt with high MgO content. On the basis of maximum Fo content of an olivine crystal in a komatiitic sample, we have estimated MgO percent and temperature of parent melt as much as 23.74% and 1470^ºC -1535 ^ºC respectively. High TiO₂ contents of pyroxene and spinel crystals indicate that their host magma must have been originated from a fertile mantle source, similar to OIB and /or LIP sources, indicating the probable role of a mantle plume in petrogenesis of these rocks.

The study area is located about 110 kilometers southeast of Mashhad and approximately 40 kilometers southeast of Fariman. The area is considered to be a part of the central Iran zone. It includes metamorphic rocks with different protoliths consisting of pelitic, carbonate and quartz - feldspathic rocks. The metamorphism in the study area is considered to be a contact regional metamorphism with a low pressure - high temperature grade. According to petrographic studies, the metamorphism in the region reached the upper limit of amphibolite facies.  On the basis of different mineral assemblages, three zones were recognized, including Andalusite-Cordierite, Sillimanite - Andalusite, and Sillimanite – K-Feldspar zones. Using Thermocalc software, the average temperature and pressure for the peak of metamorphism in the metapelitic rocks are 664 ºC and 2.5 Kbar respectively. Based on calculated maximum pressure (2.5 Kbar), the depth of ~7.8 Km for the metamorphism is estimated.

Gabbroic intrusions are located about 40 Km southeast of Fariman in Central Iran zone along the Fariman- Torbatjam road that could be seen at the end of Bardoo river and in Chahak village. Previous studies have emphasis on the age and genesis relationship between granites and gabbroic rocks. So in order to investigate this matter, granites and gabbroes  dated by using U-Pb method in Oslo University. Granites show the age of 548.3 Ma that is concarrent with the formation of schists during high temperature metamorphism in Fariman area. Dating of gabbroic rocks suggest an age of 471.14 ±0.85 mainly Early Paleozoic age that is younger than magmatism formed granites. Introducing Ordovician plotunism in this area is very important for reconstruction of Caledonian event. It seems that the formation of Gobbroic rocks is as a result of a short orogeny event due to opening of paleotethys during ordovician and Silurian.

The Bozjani copper deposit is located about 30 km west of Fariman city, Khorasan Razavi Province. Host rocks to mineralization are mostly pridotites and basalts of Fariman ophiolitic sequence. Ore body consists of two parts: lower and upper. Lower part has formed a stringer of primary sulfides as stockwork, veinlets, and disseminated. Uppermost part has lenticular shaped dominated by ribbon-like, fine grain and rounded primary sulfides. Mineralogical investigations show pyrite, marcasite, chalcopyrite, bornite, sphalerite, galena, native copper, and magnetite are primary minerals of ore body associated with secondary minerals as coprite, tenorite, covellite, chalcocite, chrysocolla, malachite, azurite, jarosite, limonite, and hematite. According to geochemistry of immobile elements, the host mafic rocks fall in boninite tectonic setting. Mass balance calculations show enrichments of Cu, Pb, Th, As, Ag, Tl and U during evolution of Bozjani copper deposit. The results of host rock, structure, texture, mineralogy and geochemistry in this research reveal that Bozjani deposit resemble volcanic massive sulfide deposit dominated by mafic rocks. Evolution of this deposit is related to four stages including hydrothermaly alteration, seafloor weathering, regional metamorphic and weathering of terrestrial.

The studied area is located on the border of Alborz and Central Iran structural zones in North-East of Iran. At the outcrops,several strata units of granite and volcanic rocks (about 630-680 m.a) along with the structural elongation of northwest-southeast are present. The studied microstructures are in a narrow range along the Fariman-Torbat-e Jam shear zone, which seems to be the result of structural functions. Brittle and ductile structures and microstructures in Proterozoic intrusive and volcanic rocks of the Fariman-Torbat-e Jam orogenic belt and various types of metamorphic behaviours have been investigated in detail in this research. The results show the diverse performance of deformation mechanisms, especially recrystallization of the bulge type and recrystallization with grain boundary migration (BLG, GBM). According to the detection of malleable structures in the deformation zone of the Fariman-Torbat-e Jam, brittle density increased with irregular intervals, moving away from the centre of the shear zone, which indicates the characteristics of the core and cover of the mentioned brittle zone. Various microcrystalline structures, especially microfractures and microcracks, wave quenching of quartz crystals, core and cover structures in porphyroblasts, recrystallization of protrusions and grain boundary migration at high temperatures can be seen in many and varied along the entire length of this deformed shear zone.
