Bagham pluton is located in 23 km of the southeastern of Ardestan and it is near the main road of Esfahan-Ardestan. The study area is a part of central Iranian zone and Urumieh-Dokhtar magmatic belt. Minerlogically, the rocks include plagioclase, pyroxene, amphibole and opaque. The rocks have SiO₂ = 44.75-47.08 and occur in gabbroic field. The chondrite normalized REE pattern show low enrichment in the LREEs relative to HREEs. The negative Nb and Ti anomalies in primitive mantle and MORB-normalized multi-element diagrams of the rocks are characteristic of island arc magmas. Also, enrichment in LILE and depletion of HFSE may indicate a subduction-related tectonic setting. Moreover, on based of the values of specific ratios (e.g. low Ti/V, Ti/Sc and high CaO/TiO₂ and Al₂O₃/TiO₂) can define a depleted or refractory magma source and on other hand, demonstrate the similarity of the mentioned rocks to tholeiitic rock with low boninitic affinity.

The most important geological units in East of  Sarbisheh are Upper Cretaceous ophiolites assemblages that are predominantly serpentinized ultramafic in composition (dunite, harzburgite and pyroxenite). Chromite deposits in these rocks have generally various forms such as lenticular, layered and disseminated with varying dimensions. Textural studies on Golab Chromites show that they have primary textures such as massive and disseminated as well as secondary textures including cataclastic, mylonites, bereccia and extensional. Geochemistry of Golab Chromites points to average amounts of Cr₂O₃ (42.26%), MgO (17.23%), TiO₂ (0.36%) and Al₂O₃ (10.5%). The ratio Cr/Cr + Al (0.79 to 0.93) indicates that these chromites are enriched in Cr and depleted in Al. The high Cr₂O₃ and MgO contents in the Golab Chromite suggest that they were crystallized from a magma having relatively high degree of partial melting. High MgO content and Cr#, Mg# in Golab Chromites are comparable with typical parental boninitic magma. Podiform Chromitite deposits in East of Sarbisheh were probably formed in the mantle sequence, the latter was generated in the supra- subduction zone (SSZ). Golab Chromite are formed similar to Lubasa Ophiolite South Tabat.

The chromitite ores of Sabzevar ophiolitic zone could be divided into two groups of high Cr and high Al. The concentration of Cr₂O₃, As, S and some heavy metals (Cu, Ni, Ag, Co, Zn) is higher in high Cr samples; while high Al chromitites show higher concentration of Al₂O₃, SiO₂, TiO₂ and other trace elements. The high Cr chromitites have higher PGE than Al-rich samples and PGE concentration increases with Cr₂O₃. The high Cr chromitites have fractionated PGE chondrite- normalized patterns with negative slope (Pd/Ir = 0.25) and high IPGE/PPGE (average 6.22); while high Al chromitites show unfractionated and relatively flat patterns
(Pd/Ir = 1.9, IPGE/PPGE = 2.88). The PGE composition of high Cr chromitites indicates they are formed by high degrees of partial melting (boninitic melt) in arc setting. In contrast, Al- enriched samples have been produced by low degrees of partial melting (toleiitic melt) beneath spreading centers (i.e., mid-ocean ridges or back-arc basins). The results of PGE composition of Sabzevar chromitites are coincident with chemical composition data of chromite crystals in these samples.

Cheshmeh-Bid chromite deposit is located in Nayriz ophiolite, about 200 km northeast of Shiraz. The ophiolite sequences in this area include ultramafic rocks (dunite, harzburgite, and pyroxenite). In this deposit, chromites are present in the mantle-crust transition zone and are enclosed by dunite. Based on chemical studies of major elements, chromite is depleted from Al and Ti elements and enriched by Fe, Cr and Mg. The calculated values of TiO₂, Al₂O₃ and FeO/MgO indicates that the parent magma is the Boninite magma type with composition equilibrium to the podiform chromites. These chromitites are the result of relatively high melting of the mantle and Boninite melt, which are formed as a result of rising and mixing of magma with mantle harzburgites in the upper environment of the subduction zone. Variations in the chromite mineral composition along with the textural changes in host ores indicate the injection of at least two mineralizing melts in the study area.
