The Miocene Qohrud granitoid intrusion consists of granite, granodiorite and tonalite and is located in the Urmia-Dokhtar magmatic belt. Intrusion of magmatic rocks into the various sedimentary rocks including shale, sandstone, limestone and marl, with Jurassic to Eocene age, has caused contact metamorphism of the surrounded rocks. Varity of hornfelses and skarns are formed in this regards. Hydrothermal activities, following magma intrusion, were affected more actively. Large automorph quartz crystals, having variety of structures, have formed within factures of different host rocks. Some of the detected structures for the Qohrud authomorph quartz crystals are including of normal or prismatic, hexagonal, trigonal, Muzo, Tessin, Dauphine, needle, Phantom and stalagmite, parallel-reverse and parallel-aggregate crystal growths, left/right quartz, Japanese twining law forms. Various structures and morphologies of the Qohrud authomorph quartz crystals can be attributed to various factors such as different lithologies of the host rocks, hydrothermal liquids following granitoid intrusion and late stage intrusion of dykes.

The intrusive bodies of Karaj-Taleghan axis in Central Alborz constitute, intruded the pyroclastic rocks of Karaj Formation in the form of sill, lopolith, stock and plug with distict distribution. Based on microscopic studies, these bodies have similar lithological composition and include olivine gabbro, olivine monzodiorite, olivine monzonite, pyroxene monzonite with felsic dikes of syenite. The major minerals of these rocks are plagioclase, alkali feldspar, pyroxene, olivine and biotite. Biotite is one of the most prominent ferromagnesian mineral in the studied bodies. Compositionally, it is plotted between the field of annite and siderophylite. Most of these biotites are primarly magmatic and some are plotted in the field reequilibrated area. Based on the FeO*, MgO and Al2O3 binary and ternary diagrams, the studied biotites plot in the calc-alkaline orogenic field and crystallization temperature has been calculated between 640º to 770 ºC. Furthermore, the calculated pressure of biotite crystallization, based on Al barometer, is 0/27 to 2/58 KB (average1/06 KB). The total aluminum content of biotite in intrusive bodies at Karaj-Taleghan axis ranges from 2/25 to 3/01. Ziyaran plutonic complex shows good potential for iron-copper mineralization and Prachan and Shekarnab bodies show high potential for lead and zinc mineralization.

Mineral identification by spectrometry in the middle Infrared (MW-IR) (Case study: kaolinite and carbonates)
j.tarrah@yahoo.de
1
Infrared spectroscopy (IR) is a powerful tool to decipher the molecular groups in the minerals. This technique of detection, using atomic vibrations of molecules, that is identified through a process of absorption, makes possible the necessary mechanisms of phase analysis of minerals. In this paper, after a brief description of infrared spectroscopy, two groups of minerals will be explained by this method: Determination of the modification of the mineral kaolinite in OH spectrum (region 3700 - 3400 cm-1) in fine to medium particle fraction <0.63 mμ in a sandstone and behavior of 2 carbonate minerals (dolomite and calcite) in the range of 2000 - 600 cm-1. The Type of kaolinite (in fine and middle class clay of the sandstone) was determined using the different spectrum as fireclay. The shift of the absorption bands of carbonate in the range of 2000 - 600 cm-1 is significant. This shift in the absorption spectrum shows that, where appropriate, a quantitative analysis can be achieved by calibration.

Investigation of skarn formation using petrographic, mineral chemistry and fluid inclusion data, south west of Khaf,
(southeast of Razavi Khorasan Province)

Keybarkuh Skarn is located in southwest of Khaf and northeast of Lut block in the Razavi Khorasan Province. Cretaceous limestone in the study area was intruded by granitoid plutons and as a result the skarn and related iron minerals were formed. The most important minerals in Keybarkuh skarn are garnet (andradite-grussolar), clino-pyroxine (diopsid – hedenbergite), amphibole, epieote, magnetite, calcite and Quartz. The Keybarkuh skarn is a calcic skarn that can be divided into garnet skarn, pyroxene-garnet skarn, amphibole-epidote skarn and epidote skarne zones.The study garnets vary in compositions and contain 59.46 to 99.45 mole percent andradite. The pyroxenes belong to diopside-hedenbergite solid solution series and contain 48.54 to 67.25 mole percent hedenbergite. The fluid inclusion studies in the western Kyberkuh carried out on the quartz veins that are associated with mineralization and skarns. The fluid inclusions in the mineralized quartz veins can be divided into two types A and B. According to microthermometry studies, homogenization temperatures of the fluid inclusion range from 200 to 340 C° and their salinity ranges from 2 to 19 wt. % Nacl equi for the A-type and 34 to 40 wt. % Nacl equi for the B-type showing that salinities of the B-type fluid inclusions are considerabley higher than those of the A type fluid inclusions. Presence of two types of fluid inclusion with high and low salinities in the the western Kyberkuh is probably due to circulation and mixing of the magmatic and meteoric waters. The skarn minerals were probably formed during two stages of prograde and retrograde in the Keybarkouh at high to intermediate fO2. The Fe mineralization is mainly associated with prograde skarn and the B-type fluid inclusion. The fluids that prouduced the prograde skarn and iron mineralization were probably derived from magmatic waters.

The Mombi bauxite deposit is located about 160Km northwest of Dehdasht in the Zagros Simply Folded Belt. The bauxite deposit exhibits an ooilitic and pisolitic texture. It contains higher amount of boehmite than those of diaspore, hematite, kaolinite, and anatase. This study uses the geochemistry of immobile elements in order to calculate the mass changes that took placed during weathering and bauxitization. The results reveal that elements such as Si, Fe, Mg, P, K, Ba, Sr and Zn are depleted, while Al, Zr, V, Cr, Ni, Ga, Y and LREEs indicate positive mass changes during the weathering and bauxitization processes. In addition, Nb, Hf, Ta, Rb, Cs, U and HRRE exhibit little changes, suggesting relatively immobile features. Interelemental relationship analyses of the ores, by using R-mode factor analysis, revealed a number of key findings: (i) some low solubility elements were concentrated in detrital zircon (Zr), in anatase (Ti), and possibly in boehmite, hematite and detrital minerals (Ga) during the later stages of bauxitisation; (ii) Fe was concentrated during humid climatic conditions, whereas Al accumulated during dry conditions; (iii) similar and meaningful weightings for U and Th suggest that heavy minerals frequency would be locally important in controling the uranium behavior; (iv) distributions of LREEs and HREEs are controlled by the stability of the carrier complexes of REEs and the existence of REE-bearing mineral phases; and (v) (La/Yb)n ratio values suggest that little LREE/HREE fractionation occurred during bauxite formation and (La/Yb)n ratio fluctuations may also be indicative of fluctuations of pH in soil solution.

The enigma of inherited Zircon crystals in Qalaylan plutone, Clues from the Gondwana crust in the rocks with primitive isotopic signatures
1
The Qalaylan pluton of Late Jurassic age is composed of intermediate and felsic rocks that crop out in the northern Sanandaj-Sirjan Zone. A body is comprising alkaline, high K, Ferroan A1-type rocks with contrasting aspects; whiles, Nd-Sr primitive isotopic composition consistent with a mantle source. On the other hand, inherited zircon cores (with a range of 230 – 2700 Ma) and elevated Nd model ages (Avg. »670 Ma) indicate that the source of these rocks was not juvenile mantle-derived subduction related magma. Unusually large proportion of inherited zircons demonstrates that fast and non-equilibrium melting of pre-fertile crust with primitive isotopic signatures was the source of these rocks. Zoning and porphyritic texture of the body, oscillatory zoning of plagioclase grains and unusually amount of pre-magmatic zircons all are evidences of non-equilibrium condition as a result of fast cooling rate of parental magma of Qalaylan.

Gol-e-Gohar and Rutchun metamorphic complexes in south-east of Sanandaj-Sirjan metamorphic zone contain alternation of meta-sedimentary, meta-basites and impure meta-limestone that have been affected by different metamorphic events and deformational phases. In the first metamorphic event that was associated with the first deformational phase, muscuvite, biotite and garnet minerals were formed and oriented along the first schistosity (S1) just parallel to the primary layering. The second event acted simultaneously with the second deformational phase and led to the overgrowth of the previous porphyroblasts and re-orientation of them parallel to the second schistosity. The third metamorphic event in associated with the third deformational phase that produced fine-grained muscuvites along the shear zones. The first metamorphic event occurred at the temperatures of 440-460 ºC and pressures of 3/5-4/5 kb, but the second metamorphic event (peak of metamorphism) took place at the temperatures between 570-600 ºC and pressures between 7-8 kb that are correspondent with early Cimmerian orogenic phase

Amphibolites in the studied area have upper Triassic age and seen with various rocks such as micaschiste, marble and metadolomite. These rocks with dark and green color contain minerals as hornblende, plagioclase, actinolite, tremolite and epidote that dark and light minerals were separated and seen as dark and light bands. Based on whole rock geochemical analysis, these rocks belong to sub-alkaline series, and show tholeiitic trend and basaltic origin. So, amphibolites in this area are ortho-amphibolite type. Based on tectonic discrimination diagrams, protolithic rock of these amphibolites revealed to oceanic crust and tectono-magmatic setting in within plate environment. The chemical composition of amphibole in amphibolites show the calcic amphibole group and different mineral types as Tremolite - actinolite, Pargasite and Magnesio-hornblende. Based on the obtained results from the analysis of plagioclases in amphibolites, in triangular diagram Ab-An-Or, plagioclases mostly been located in andesine- oligoclase to labradorite range in this diagram. Estimates of temperature and pressure of crystallization in plagioclase and amphibole minerals base on thermobarometric relations using paired minerals coexisting hornblende - plagioclase temperature been showed the ranges between 588 to 819 °C with an average of 704 °C and a range of pressure between 2 to 6 Kbar for these minerals.

The Lakhshak intrusive assemblage consisting of a granodiorite pluton and monzodiorite and dacite dykes are parts of Zahedan-Saravan granitoid belt which cover about 90.5 km2.. Dykes are parallel with NE-SW trends and comprise about 20-30 percent of the pluton. The granodiorite plutonis granular in texture and comprises mainly consists of plagioclase, K-feldspar, quartz, green hornblende, and biotite. The accessory minerals are zircon, titanite, apatite, allanite and Fe-oxides. The monzodiorite dykes are fine-grained and mainly consist of plagioclase and brown hornblende, while dacite dykes show porphyritic texture and consist of plagioclase, sanidine, quartz, biotite and hornblende (few percent). The best zircons and titanite minerals were selected from the study rocks for U-Pb dating. The results of U and Pb isotopic ratios determined by Mass spectrometer showed that the granodiorite rocks from the Lakhshak pluton were crystallized at 29.80 ± 0.048Ma ago; and then microdiorite and dacite dykes were cut the pluton at 28.9 ± 0.11 and 28.11± 0.69 Ma ago, respectively.

The study area is located in NW of Iran, East-Azarbaidjan Province in north Varzeghan. Plagioclase, amphibole and biotite are the major minerals and sphene, apatite, and quartz are accessory minerals. The texture of these dykes are porphyrytic with fine to medium matrix. Mineral chemistry analysis revealed that the composition of Plagioclase varies from andesine to oligoclase and the biotite varies from annite to siderophyllite. Amphiboles are principally of calcic-type and show magnesio-hornblende composition. These amphiboles are related to subduction zones and are concordance with active continental margins related to subduction. Dykes thermo-barometry, using total Al3+ content in amphibole, shows that amphibole in quartz-dioritic dykes were crystallized at 800˚C and 4±0.5 kbars. Biotite thermometry in late dykes shows the crystallization temperature of 700 to 750 ˚C. High oxygen fugacity (-10 to -17) imply an oxidation magma and its formation in convergent plates. Based on magma character and nature determining diagrams according to chemical composition of amphibole, studied samples lie in sub-alkaline to alkaline magma series. Based on tectono-magmatic diagrams, amphiboles of the area lie in the field of suprasubduction related amphiboles. According to the amount (less than 1.5) AlIV, all of studied amphiboles placed in active continental margins related to subduction field.

Gneisses of the northern part of the Zayandehrood Dam Lake, structurally, are located in the Sanandaj-Sirjan zone. The gneises with phengitic marble and metabasic bodies comprise a part of high-pressure units in the North Shahrekord metamorphic complex. Minerlogically, the rocks consist of quartz, garnet, phengite, k-feldspar, albite, tourmaline and rutile with zircon grains. Field (alternation of associated rocks), mineralogical and geochemical evidences are used for determining protolith of the gneisses as igneous source (ortho) or as sedimentary source (para). The geochemical evidences are used such as P2O5/TiO2 vs. MgO/CaO digram, and Niggli values c against al-alk, ti and al-alk, the frequency of Cr and Ni. In addition to, the mineral assemblages indicate a sedimentary protolith (para gneiss). The chemical composition of the protolith is caused by the felsic igneous resources of evolved crust which are plotted in the range of the Late Archean until post Archean in the diagram Ni against Cr. Our findings, especially geochemical evidences, show that the paragneises have sedimentary source, in contrast to what was previously suggested that they are orthogneiss. The protolith of the paragneisses have been formed in an active continental margin or the back-arc basin.

Gabbrodioritic pluton is located in S-Qorveh in nourthern parts of the Sanandaj-Sirjan Zone. Petrographically, amphibole and plagioclase are main minerals in these rocks. Amphiboles are calcic-type, and their composition varied between ferro-hornblende to magnesio-hornblende. Anortite contents in plagioclases are between 81 to 39 (%) and these crystal are labradore -oligoclase in composition. According to coexist hornblende-plagioclase and Al in amphibole geothermometry methods, temperatures of crystallization are yielded ~723°C. In the later method, data indicates that the investigated rocks were emplaced at average pressure of 3.5 Kbar corresponding to a depth of ~12 Km. Oxygen fugacity was high in magma. Na2O content in amphibole and their calc-alkaline nature show gabbroic diorites are related to subduction setting. Mg#, Al2O3 and TiO2 contents in hornblende indicate mixing of crustal and mantle sources to generate magma of the Darvazeh gabbrodioritic magma. Variations in the composition of plagioclase may be related to H2O content in environment and the role of chemical variation due to input of crustal materials.

Tertiary volcanic rocks including andesite, trachydacite and rhyodacite with pyroclastic rocks cropped out in east of Sarbisheh at Southern Khorasan. The main minerals in andesites are plagioclase, pyroxene, amphibole and biotite and for acidic rocks include plagioclase, quartz, sanidine, amphibole and biotite. On the basis of microprobe analyses, the composition of plagioclases in andesites ranges from Ab62.7,An30.2to Ab35.5, An62.9and are andesine to labradorite. Pyroxenes are enstatite and have compositional range of En50.6-57.8, Fs39.8-47. Orthopyroxene thermometry represents temperature of 1050 to 1100oC with pressures of 1 to 10 Kbar. The studied rocks have medium to high-K calc-alkaline and shoshonitic nature. Geochemical characteristics, such as enrichment in LILE, depletion of HFSE and Zr/Y>3, indicate magma relation to subduction zone and active continental margin. Relatively low values of (La/Yb)N(7.17-11.68) and Dy/Yb(<2) in Shoushk lavas, indicated that partial melting of mantle took place in the spinel-garnet transition zone.

The studied area is located in the north of Rudan city and is a part of Kahnuj - Rudan - Minab ophiolite belt. The studied rock are harzburgite and lherzolite and are composed of olivine, orthopyroxene, clinopyroxene and chrome – spinel (as a minor). According to microprobe data, the amount of MgO in the olivines ranges between %50.17 to %50.55, so these olivines are forsterite. Clinopyroxenes are diopside and spinels contain chrome. Detail microprobe studies on the chrome - spinel of ultramafic lherzolites prove that they are high in Mg#(%71-%77) and Al2O3 (52.98 to 46.31 Wt%) ) and low in Cr# (%0.14 - %0.22). (Cr/Al) ratio in the spinel of lherzolites is 0.19. The amount of Fe3+ in the chrome - spinel of ultramafic Peridotites is very low (<0.1 Wt%) that shows the crystallization has taken place in low oxygen fugacity. On the basis of spinel mineral chemistry, lherzolite samples are located in oceanic peridotites tectonic position (ABYSAL) and formed in the mid-ocean ridges (MORB).

The synthesis and X-ray diffraction analysis of a new acidic salt, [4-methyl-phenyl ammonium][(O-phenyl)(hydroxyl)phosphate], [4-CH3-C6H4NH3][(C6H5O)P(O)(O)(OH)], is reported. This compound crystallizes in the monoclinic system, with space group P21/c
(a = 9.5147(4) Å, b = 23.2158(10) Å, c = 13.2740(6) Å and b = 111.244(4)°) with four independent components including two cations and two anions in the asymmetric unit. In the crystal, adjacent components are linked together through N–H∙∙∙O and O–H∙∙∙O hydrogen bonds building a ladder arrangement along [100] axis. The Hirshfeld surface analysis and two-dimensional fingerprint plot were used to study intermolecular interactions in the structure. The N–H∙∙∙O and O–H∙∙∙O hydrogen bonds are the characteristic interactions (red areas in the Hirshfeld surfaces). Two sharp spikes in the fingerprint plots of two anions are related to the O…H(O) contacts, while one nearly sharp spike in the fingerprint of two cations is assigned to the O...H(N) contacts.

Bismuth titanate (B14Ti3O12) ceramic have attracted many attentions due to their various significant properties and applications and have been studied by many researchers. In this study, the related solutions were prepared by using sol-gel technique, and coated on glass substrates, using the spin coating instrument. Then, the structural and optical properties of the prepared thin films were investigated. In more details, at first the primary cell was prepared using bismuth nitrate, acetic acid, titanium isopropoxide, 2-methoxyethanol and acetyle aceton with certain molar ratios. After mixing and stirring the ingrediantes, the sol-gels were formed. Then they were coated on glass substrates with a specific speed, using spin coating instrument. Also in this study, we investigate the structural and optical properties of Bismuth Titanate (Bi4Ti3O12) thin films. In ordere to determine the type of phases, surface morphology and optical properties of the prepared thin films, the X-ray difraction patterns, scanning electron microscopy (SEM) and optical absorption-transmission spectra analysis of Sun and Pole were used, respectively.
