Abstract
On the basis of field studies, mafic-intermediate bodies of Kashmar are subdivided into the old series (often stocks of gabbro, diorite, quartz diorite/monzodiorite) and the new series (quartz monzodiorite swarm dykes). In terms of crosscutting relationships, old series has the age between oldest volcanic units (57 Ma) and Eocene granitoids (40 Ma), but the swarm dykes are attributed to the post Eocene (Oligocene?) in age. Mafic-intermediate bodies with the high-K calc-alkaline to shoshonitic, metaluminous to low peraluminous, LILE/HFSE and LREE enrichment [(La/Yb)N=5.3-6.8] and depletion of HREE characteristics are reminiscent of the arcs in subduction zone. These features accompany with negative anomalies of Eu indicating magma generating at the depth of plagioclase stability and contaminiation of magma to continental crust, which remains during the melting of the garnet rock. Linear trend of the major oxides and trace elements in Harker diagrams indicate in importance of fractional crystallization of magma evolution. Average of initial isotope ratios of 87Sr /86Sr and 143Nd /144Nd (in age 50 Ma) for the old series samples are between 0.7054 /0.7062 and 51262-0.51264 respectively, and the εNdi has a range of 1.08 to 1.42. Average of initial isotope ratios of 87Sr /86Sr and 143Nd /144Nd (in age 30 Ma) for swarm dykes are 0.7056 and 512623 respectively, and the εNdi amount is .059. εNdi positive values and low ISr of all rocks with their TDM (0.6-0.8) implying that they form from partial melting of lithospheric mantle source, which modified to earlier subduction processes melts. Based on the Th/Ta versus Nb/Ta and Nb/Y versus Zr/Y charts, both subduction and rift forming processes were involved in the formation of Kashmar rocks. This feature is compatible with subduction of Sabzevar oceanic crust to the Lut block.

Abstract
Erythrite (Co3 (AsO4)28H2O) is one of the rare arsenic minerals which belong to the vivianite group. A recent discovery in Tarikdarreh prospect area (northeastern Iran) found erythrite along with scorodite and hydroxides of iron have been recognized as a supergene alteration product of primary arsenic mineral in surface arsenopyrite ± pyrite mineralization veins zones. A specimen of erythrite has pale red to shiny pink color and aggregates to form into a bright red color star with a radial structure. When observed under a microscope it is elongated in C crystal axial with pleochroism. This mineral has a monoclinic system, space group C2/m and the unit-cell parameter constants are a = 10.251, b = 13.447, c = 4.764, β = 104.98. The crystalline structure of this mineral forms chains of tetrahedral of arsenic, octahedra of cobalt-iron which bind with oxygen and hydrogen. Scanning electron microscope images of this crystal exhibit a timber shape and SEM-EDX analysis have confirmed As, Co elements in this crystal structure and chemical composition. An XRD examination reveals arsenopyrite as the main sulphide phase in the mineralization zone and analysis by ICP-Mass have shown that they have high levels of cobalt element. Surface weathering of arsenopyrite has provided aqueous species of cobalt and arsenide for crystallization erythrite. On the other hand erythrite can only be stable in the range of 6 to 8 pH conditions, and then Eh-pH condition has an important role in controlling the stability and solubility of erythrite.

Abstract
Jalambadan mineralization is located in northwest of Sabzevar, Khorasan Razavi Province, and in the southwestern Quchan-Sabzevar magmatic arc. Geology of the area consists of Eocene andesitic to trachyandesitic volcanic rocks, which are intruded by monzodioritic to dioritic subvolcanic units. Mineralization occurs in intrusive rocks and surrounded volcanic units as disseminated. Pyrite is the main primary mineral and malachite, hematite, goethite, and limonite are the secondary minerals. Well alteration developed in this area and the mineralogy of them consist of quartz, sericite, kaolinite, chlorite, epidote, and calcite. Gold anomaly is between 0.018 to up to 2 ppm and copper content is maximum 509 ppm, especially at eastern half of the area. Monzodioritic to dioritic intrusive rocks had major role in mineralization. The texture of intrusions is porphyry and plagioclase, pyroxene, and hornblende are the common minerals. Geochemically, the intrusions are calc-alkaline I-type granitoids, which are formed in subduction zone from partial melting (7 to 15%) of spinel lherzolite. Based on tectonic setting, geology, type and development of alteration and mineralization, and geochemical anomaly, Jalmbadan occurrence is porphyry Au±Cu mineralization.

Abstract
The Kuh Zar Au-Cu deposit is located about 100 km southeast of Damaghan city. Structurally, this area is part of the Alborz Magmatic Assemblage (AMA). The oldest rock units in the Firuzeh-Gheychi area consists of syenogranite and tourmaline biotite granodiorite units. These units were intruded by quartz monzonite porphyry stocks. Pyroxene diorite porphyry and hornblende diorite porphyry are younger than all of the rock units mentioned. They were intruded by syenogranitic and monzogranitic dikes. All units have been affected by QSP, propylitic, argillic and silicification-tourmalinization alteration zones. Mineralogy studies show that the seven main groups of veinlets in the area included I: quartz-pyrite-chalcopyrite-tourmaline, II: quartz-chlorite-pyrite-tourmaline, III: quartz-pyrite, IV: quartz-pyrite-chalcopyrite, V: quartz-tourmaline-pyrite, VI: tourmaline-pyrite and VII: pyrite-chalcopyrite-chlorite-tourmaline. Fluid inclusion petrography also shows that dominant primary fluid inclusions of the two-phase LV and single-phase L are the rich liquid. Microthermometric studies show that the homogenization temperature and salinity range for type-I veinlet fluid inclusions are 428 to 486 ˚C and 14.4 to 16.7 Wt.%NaCl, type-II veinlet fluid inclusions are 436 to 500˚C and 22.5 to 23 Wt.%NaCl, type-III veinlet fluid inclusions are 367 to 479˚C and 15.3 to 23.5 Wt.%NaCl, type-IV veinlet fluid inclusions are 363 to 407˚C and 16.1 to 17.4 Wt.%NaCl and type-V veinlet fluid inclusions are 421 to 516˚C and 20.2 to 21.4 Wt.%NaCl, respectively. Fluid inclusion studies show that two types of magmatic fluid with similar temperature, but different salinity have a role in the formation of the deposit. The boiling also led to deposition of metals, instability complexes and formed mineralization in the Kuh Zar deposit. The high temperature and intermediate salinity of fluid inclusions, diversity, and extension of alterations, and types of mineralization are similar to copper porphyry deposits.

Abstract
The Golgohar iron mine is located about 55 km southwest of Sirjan in the Sanandaj-Sirjan structural zone. We distinguished five mineralization zones, on the bases of mineral assemblage with magnetite. The gangue minerals are pyrite, pyrrhotite, chalcopyrite, siderite, apatite, serpentine, talc, chlorite, amphibole, calcite, dolomite and quartz. All chlorites are tri-octahedral in nature. The chlorites in MPPC and MTCA are pennine and pennine-clinochlore, respectively. The chlorites in chlorite schists have wider compositional range from pennine, clinochlore, pycnochlorite to ripidolite. Chlorite in mica schists and hornblendite are ripidolite. The chlorites with the highest amount of Mg have formed from mineralizing fluid. With decreasing of fluid/rock ratio, the chlorites show trends of decreasing Mg and increasing Fe and AlIV. Increasing of the Mg/(Mg+Fe) ratios from host rock to mineralization zones are different to those from the iron formaion. The content of minor elements in the structure of chlorite depends on the fluid composition, other crystallized minerals from the fluid, water/rock ratio and the composition of host rocks. The chlorite formation temperatures are ranging between 245°C and 415°C. MPPC zone have the lowest temperature (avg = 301°C), so Mg-rich chlorites are formed at lower temperature rather than Fe-rich Chlorites.

Abstract
Gushfil deposit is located SW Isfahan within Malayer-Isfahan Metallogenic Zone. Mineralization occurs at contact of Jurassic shale and Cretaceous dolomite as epigenetic with structural control. Paragenetic minerals are sphalerite, galena, and pyrite associated with dolomite, quartz, organic matter, and minor barite as gangue minerals. These minerals show berrecia, veinlets, open space filling, and dessiminated textures. Dolomitization and silicification are the most important alteration zones. Ore chemistry indicates galena is Ag and Sb-rich and Bi-poor. Sb/Bi ratio in galena is up to 14, which is indicator of low temperature deposits. Sphalerites are Fe and Cd-rich type. Based on fluid inclusion studies, formation temperature of Gushfil deposit is 223 to 302ºC. It is formed by NaCl and CaCl2-bearing fluid with 9.5 to 16.7 wt. % salinity. Host rock type, stratabound and epigenetic mineralization, post- sedimentary fault controlling, texture, ore types and gangue minerals, and no associated with igneous activity indicate Gushfil deposit is similar to MVT deposits, but ore-fluid temperature is higher than typical mineralization in the world.

Abstract
The Damanghor gold mineralization occurrence is located in north of Bardaskan, Khorasan Razavi Province, and Taknar zone.The geology of the area consists of Precambrian green sericite schist and metarhyolite, intruded by diabase. Mineralization in this area is in vein form with N50E stribe and 70NW dip and hosted by schist and metarhyolite with 300 meters length and 2 to 35 meters width. Disseminated and veinlet mineralization includes primary minerals of pyrite and chalcopyrite and secondary minerals such as covelit, malachite, azureite, hematite, goethite and limonite with quartz, sericite, and lesser clay minerals. Silicic-sericitic alteration is the most important alteration zone associated with mineralization. Based on rock samples taken from explorative trenches, gold anomalies range from 0.3 to 12.5 ppm, silver up to 30 ppm, copper up to 860 ppm, and zinc about 9252 ppm.Based on the evidence of host rock, the type and extent of alteration, structural control, shape and type of mineralization and primary minerals and geochemical anomalies, the occurrence of Damanghor gold mineralization is epithermal with intermediate sulfidation state that is related to hydrothremal derived from Cenozoic magmatic activities.

Abstract
Kuh-e-Shuru prospect area is located in the southern Ferdows, South Khorasan Province, and is one of the vein-type mineralization, related to the Tertiary magmatic activities of Lut block. Mineralization, as epigenetic, is formed in host rocks of shale-siltstone (Jurassic), dacite, and diorite porphyry (Tertiary). Mineralization with open space filling, breccia, and replacment textures is formed in fault zones and can be divided into two main stage including: 1. Quartz-galena-pyrite-realgare with argillic-sericitic alteration and 2. Quartz-stibnite-pyrite-realgar with silicified alteration. Maximum geochemical anomalies in veins are for antimony with 14%, lead 293 ppm, arcenic 98 ppm, and zinc 168 ppm. Microthermometric measurements show quartz-sulfide veins are formed from a fluid with temperature of 160 to 224ºC and salinity of 13.7 to 22.8 NaCl wt. % equivalent. The mixing of hot and brine magmatic ore fluid with cold and low salinity meteoric fluid and boiling can be casued metal deposition. Based on geological studies, mineralogy, texture and structure, geochemistry, and fluid inclusion data, Kuh-e-Shuru prospect area can be classified as epithermal deposits.

Abstract
Sangan prospect area is located northeast of Torbat-e-Heydarieh in Khorasan Razavi Province and in relation to regional geology, it is situated in eastern section of Khaf-Kashmar-Bardaskan magmatic belt. Metamorphosed sediments of the Shemshak Formation (slate, schist, quartzite) is the oldest unit, which is intruded by Kafardoogh granitic intrusion. The dikes of quartz monzosyenitic and dioritic composition in the last magmatism stage have intruded into the fore mentioned units. Structurally-controlled mineralization has formed along subsidiary faults, branching from the Doruneh major fault, with general trends of NNW-SSE to WNW-ESE (dipping 60-90 degrees southerly and westerly) and NE-SE (dipping 50-70 degrees easterly). The major parts of mineral deposit has occurred in fault zones of metamorphosed Shemshak Formation due to deposition of mineralizing hydrothermal fluid in open spaces of faults as cement of fault breccia fragments. The hypogene mineralization is characterized by chalcopyrite as the main ore mineral and minor amount of pyrite together with quartz and barite as gangue minerals. Malachite, chrysocolla, chalcocite, neotocite and secondary iron oxides constitute the mineralization of oxidation and supergene zone. The occurrence of structures and textures as vein-breccia, open space filling, veinlets and secondary replacement are characteristics of mineralized veins in this area. Silicification is the principal alteration associated with mineralization. The geochemical survey of veins indicates not only high content of Cu (more than 5 percent), but also considerable anomaly of Au up to 0.4 ppm while other significant metallic elements are not anomalous. Cu, Pb, Zn, Ag and Mo have good positive geochemical correlation but Au does not show correlation with other elements (except Ag). Studying two phase liquid-rich primary fluid inclusions of quartz and barite along with mineralographic studies demonstrate two phase of hypogene mineralization. Accordingly, the main phase of primary mineralization has formed from a hypogene hydrothermal fluid at temperature of 274°C to 318°C and salinity of 7.3 to 12 wt% NaCl equivalent. The late phase, which is related to barite mineralization, has been derived from a fluid at temperatures between 200°C to 259°C and salinity of 10.2 to 11.4 wt% NaCl equivalent. The temperature and salinity data represents the role of fluid mixing and dilution by cool-dilute meteoric fluids as ore-forming processes. Based on mineralogy, structure, texture, alteration, vein geochemistry and fluid inclusion studies, the Sangan mineral occurrence most resembles vein-hydrothermal deposits of epithermal Cu±Au type.

Abstract
The Balazard prospecting area is located about 120 km southwest of Nehbandan city, Khorasan Jonoobi Province, in the central parts of Lut block volcano-plutonic belt. The intrusion of a granitoid pluton into rhyolitic and andesitic rocks has led to alteration and mineralization. Hydrothermal alteration zones consist of argillic, sericite-argillic, silicic-argillic, propylitic, and advanced argillic. Sulfide and oxide mineralization occur as disseminated grains, veinlet, hydrothermal breccia and carbonate-silicic veins. The geochemical and radioisotope data are consistent with subduction related magmas that formed in an active continental margin, and these data suggesting a major interaction with upper crust during magma ascent. Microthermometric measurements of fluid inclusions yielded homogenization temperatures (Th) of 385–550 °C and moderate salinities of 7.1–21 wt% NaCl equivalent in Au bearing quartz vein, indicating the mixing of ore-forming fluids. Geology, mineralogy, alteration, fluid inclusions and geochemical studies all indicate that mineralization at Balazard area occur as both porphyry and high sulfidation epithermal systems.

Abstract
The Mahoor area is located about 135 km southwest of Nehbandan city, Khorasan Jonoobi Province, and in the central Lut block volcano-plutonic belt. The intrusion of an Oligocene granitoid pluton with diorite, quartz diorite, quartz monzodiorite, and quartz monzonite into Paleocene-Eocene volcanic rocks that led to alteration and mineralization. Hydrothermal alteration zones consist of argillic (clay minerals), propylitic (chlorite, sericite, calcite, epidote), phyllic (quartz, sericite, pyrite), and silicification. The main ore minerals include sphalerite, chalcopyrite, magnetite, pyrite, stibnite, tetrahedrite, jamesonite, covellite, cubanite, arsenopyrite and galena, occurring as veinlets and disseminations. According to crosscutting relationships, two type of veinlet have been identified at deep levels of Mahoor deposit. Type (1) Quartz + sphalerite+ pyrite ± chalcopyrite, and type (2) Quartz +pyrite +chalcopyrite± sphalerite. The homogenization temperature and salinity of fluid inclusions in type 1 of veinlets range from 315 to 575°C and 6.8 to 21.2 wt. % equivalent NaCl, respectively. Fluid inclusions in type 2 of veinlets show homogenization temperature and salinity from 177 to 454°C and 7.9 to 20.2 wt. % equivalents NaCl, respectively. The microthermometric data indicate that the ore forming hydrothermal solution evolved through boiling events and mixing of magmatic fluids with meteoric waters. Sulfur isotopic values of pyrite and chalcopyrite vary from 1.8‰ to 3.15‰, suggesting that S was derived from a magmatic source. Geology, alteration, mineralization, fluid inclusion, and stable isotope studies indicate that mineralization in Mahoor area occurred as porphyry system.

Abstract
Bijvard prospect area is located in the northern part of Central Iran zone, Sabzevar zone, about 40 km north of Bardaskan. The rock units exposed in the area include Cretaceous volcano-sedimentary rocks (andesite, basalt, graywacke and conglomerate) that syenogranite porphyry unit has intruded into them. Mineralization has structural control, with N35E trending, and has altered the andesitic rock unit. Mineralization in this area has occurred in two parts: 1- Gold-bearing ores, that are mostly associated with silica and argillic alterations within gossan zone, which is surrounded by propylitic alteration 2- Manganese mineralization has occurred within gray wacke unit. Mineralogy is simple and primary minerals are pyrite, chalcopyrite, pyrolusite and braunite and secondary minerals include goethite, hematite, covellite, chalcocite, malachite and various Mn-bearing minerals. Quartz and clay minerals associated with minor calcite are the most important gangue minerals. The maximum value of gold is 1.4 ppm and the minimum value of gold is 0.01 ppm. In addition, the amount of copper is ranging between 88 ppm and 2.2%, arsenic is 21 to 100 ppm, and zinc is 162 to 495 ppm. Based on tectonic setting, host rock, structural control, type of alteration and the absence of high and low sulfide index minerals, Bijvard prospect area is probably an intermediate sulfidation epithermal type.

Abstract
The Ghoochi area is a part of volcanic-plutonic zone of the Lut block and is located in eastern Bajestan city in the Razavi Khorasan Province. The geology of the area includes Jurassic metamorphic (slate and metasandstone), Early Cretaceous sedimentary (limstone, conglomerate and sandstone) and Late Cretaceous subvolcanic (pyroxene diorite porphyry) rocks. Mineralization is formed along faults with northwest-southeast and east-west trends in the reduced pyroxene diorite porphyry host rock (Late Cretaceous). Hypogene minerals are pyrite, sphalerite, galena, pyrrhotite, arsenopyrite, chalcopyrite, calcite and quartz with lesser amounts of chlorite. Mineralization is seen along with the structures and textures of vein-veinlet, open space filling, disseminated, replacement and exsolution. Main alterations consist of propylitic-sericitic, sericitic-carbonate-silicification and carbonate-silicification±chlorite. Maximum geochemical anomalies observed include for gold with 2639 ppb, arsenic 11065 ppm, lead 45400 ppm, zinc 19400 ppm, silver 12 ppm, and copper 725 ppm. Based on geology, alteration, mineralogy, texture and geochemistical studies, Ghoochi area can be probably classified in reduced-intrusion related gold systems (RIRGS).

Abstract
In the Bisheh area, intrusion of hornblende porphyry diorite in limestone and tuffs rocks caused skarn formation. Garnet and pyroxene are the most abundant minerals in prograde exoskarn, respectively. In retrograde processes, epidote, tremolite-actinolite, quartz, calcite and opaque minerals such as magnetite were formed. Electron microprobe analysis shows that the studied garnets are andradite-grossular solid solution. Studied garnets show variations in Fe3+/Al ratio that is related to changing conditions during growth. Studied pyroxenes are very close to diopside end member and lowest diopside content is 64.97%. Based on garnet and pyroxene composition, the average logarithm of oxygen fugacity is calculated -20.18 megapascal. The presence of magnetite, pyrite and pyrrhotite along with calcite and quartz show that metasomatism fluids probably had ƒS2~10-7 and temperature < 430°C.

Abstract
The Kimia copper area is located in the Eocene volcano-sedimentary complex northwest of Bardskan in Razavi Khorasan Province. The geology of the area includes volcanic rocks with andesite-basalt composition, conglomerate with andesite fragments, nummulitic limestone and tuffaceous sandstone. Mineralization is found in andesite and conglomerate units as well as at the border between these units in the form of vein-veinlets, disseminated, replacement and open space filling. Primary minerals are chalcocite, pyrite, and secondary minerals are malachite, caveolite, and iron oxide. The faults in this region are formed in two directions, northeast-southwest and northwest-southeast, with a slope of 45 degrees. The main veins in this zone are calcite-quartz-pyrite, calcite-chalcocite and calcite-barite-pyrite. Alterations related to veins are siliceous and carbonate and are related to igneous, propylitic, carbonate and chloritic units. The amount of copper element ranges between 6950 and 47935 ppm and other elements have low values. Based on fluid inclusion study, the minimum formation temperature ranges between 228 and 368 °C and the salinity is between 10.4 and 16.9 percent. Based on the evidence of the host rock, structure, textures and existing alterations, copper mineralization in Kimia area is Manto type.

Abstract
The Kalateh Bargh prospect area is located NW of Bardaskan, Khorasan Razavi province. Geology of the erea includes sequence of Eocene volcanic rocks with basalt composition and trachyandesite and andesite. On this sequence, there is a conglomerate unit that its fragments are mainly composed of volcanic rocks. The high porosity of the conglomerate as the host rock provided a suitable space for the formation of Manto copper deposits. Mineralization has formed in conglomerate unit as a particular horizon in the Kalate Barq area. Primary minerals include chalcocite and minor bornite and secondary minerals consist of malachite and covellite. Structure and texture of mineralization are veinlet, open-space filling, disseminated and replacement. Mineralogy of alteration zones is related to mineralization and consist of chlorite and calcite. The average copper geochemical anomaly in surface samples is 1.4 %. The presence of chalcocite and absence or low amount of iron sulfide minerals, the presence of chlorite and calcite as the main gangue minerals and lack of quartz indicate that ore solution is reduced and poor of iron and silica. Based on lithology, alteration, mineralogy and geochemistry of Kalateh Bargh prospect area is similar to manto-type copper deposits.

Abstract
Samakhon prospect area is located NW of Torbat-e-Jam in Khorasan Razavi Province. Lithology of the area includes volcanic, sedimentary and subvolcanic granitoids rocks. One type of mineralization identified in this area is vein-veinlet that hosted by basaltic to andesitic tuff in contact with limestone. Primary minerals are chalcopyrite, pyrite, and bornite and secondary minerals includes malachite, chalcocite, covellite, hematite, goethite and azurite. The most important gangue mineral with mineralization is quartz that is observed as filling open space and veinlet. Mineralization has anomaly of Cu (4.5 %) and other elements have no economic value. Based on fluid inclusion studies in quartz mineral, temperature during the formation of mineralization is 178 to 345ºC with 13.7 to 20.6 wt. % salinity. According to the geological and mineralization evidence, mineralization zones in the Samakhon area represent the Cu hydrothermal vein-type deposits.
