Continuous dunites are similar to the residual mantle peridotites, while, dunitic dykes are the remnants of mantle channels and conducted the melts toward the upper levels. Dunitic dykes are produced by reaction of suprasubduction zone related  to boninitic melts with the harzburgites and they are replacive dunites, but the large and continuous dunites have formed by partial melting of the harzburgites in a suprasubduction zone setting and so they are residual dunites.}, Keywords = {dunite, Esfandagheh, Hadji-Abad, Hormozgan, Ab-Bid ultramafic complex.}, volume = {24}, Number = {4}, pages = {621-634}, publisher = {Iranian Socity of Crystallography and Mineralogy}, url = {http://ijcm.ir/article-1-60-en.html}, eprint = {http://ijcm.ir/article-1-60-en.pdf}, journal = {Iranian Journal of Crystallography and Mineralogy}, issn = {1726-3689}, eissn = {2588-4719}, year = {2017} } @article{ author = {}, title = {Mineralogy and Cu-Au-Bi ore paragenesis of Kuh-e Dom prospecting area (northeastern Ardestan), Anarak metallogenic province}, abstract ={Modeling based on equilibrium thermodynamic and physicochemical condition suggests that Bi-rich melts can efficiently scavenge Au from hydrothermal fluids, even if these fluids are highly undersaturated with respect to Au minerals.

Garnet and pyroxene are two coupled indicator minerals that have been formed by Mg-Si-Fe-bearing fluid remained from magma crystallization. These minerals are observed extensively in the metasomatic haloes in the country rocks and could be used to determine the conditions of temperature and pressure that have been governed on skarnization. It is revealed from microprobe analysis that the garnets in the Sarvian deposit are of the grossular-andradite type that are enriched in Fe & Ca, and depleted in Mg & Mn. These garnets show a sharp zoning structure. The distributions of MnO, CaO, Al2O3 and FeO in the zoned garnets indicate that from the core to rim, their composition changes gradually from grossular to andradite. The composition of the garnets and pyroxenes in the Sarvian ore deposit is compatible with the Fe-skarn deposits. Pyroxenes in the Sarvian ore deposit are of Ca-riched diopsid-hedenbergite type. During the prograde stage in which the anhydrous minerals such as garnets and pyroxenes were formed, the temperatures are comparable with albite-epidote and hornblende-hornfelse facieses. According to the temperatures of the garnet-clinopyroxene minerals formation, the temperatures of prograde stage have been determined between 370-500 °C. On the other hand, the results of fluid inclusion studies on quartz grains obtained from mineralized veins suggest that the temperatures during the iron mineralization in the retrograde stage of skarnization have been 400-380 ° C.}, Keywords = {skarn, Sarvian, garnet, pyroxene, fluid inclusion.}, volume = {24}, Number = {3}, pages = {435-448}, publisher = {Iranian Socity of Crystallography and Mineralogy}, url = {http://ijcm.ir/article-1-77-en.html}, eprint = {http://ijcm.ir/article-1-77-en.pdf}, journal = {Iranian Journal of Crystallography and Mineralogy}, issn = {1726-3689}, eissn = {2588-4719}, year = {2016} } @article{ author = {}, title = {Mineralogy and petrogenesis of Chalu iron skarn deposit (SE Damghan)}, abstract ={The Chalu Fe skarn developed at the contacts of the part of intrusive body with monzodiorite composition and Cretaceous carbonate rocks.

Small intrusive bodies of gabbro and dioritic dykes are exposed in the area. Iron mineralization at Jalal-Abad is concealed with scarce outcrop. The main ore mineral is magnetite, which is located deeply, and  has been oxidized to hematite in shallow dopth and along fractures. Pyrite and chalcopyrite are the main sulfide minerals and bismuthinite, arsenopyrite and covellite are present in minor amounts. Cu mineralization occurred in sulphide and oxide stages as dissemination, veins, veinlet and open space filling. Malachite, azourite and atacamite are common minerals at oxide stage. Native gold was detected as inclusions smaller than 50 µm in pyrite, chalcopyrite and magnetite hosts.
