Abstarct: The Fariman area, located in northeastern Iran within the Binalud tectonic subzone, hosts one of the most significant Phanerozoic mafic–ultramafic complexes of komatiitic affinity in the region. This study examines the geology, petrography, mineralogy, alteration, geochemistry, and ore-forming potential of the Fariman komatiitic rocks and places them in the context of global models for magmatic Ni–Cu–(PGE) sulfide mineralization. The results indicate that the mafic–ultramafic units of the Fariman area form part of a Late Paleozoic (Permian) volcanic–sedimentary sequence, comprising differentiated and undifferentiated komatiitic flows, komatiitic basalts, mafic–ultramafic pillow lavas, and high-Mg basalts. Well-developed komatiitic facies, including chilled margins, spinifex zones, and cumulate sections, are present. Field observations and petrographic evidence confirm a submarine extrusive emplacement of these lavas. Associated mextamorphosed sedimentary rocks include phyllite, slate, schist, radiolarite, mextasandstone, and crystalline limestone, locally occurring in direct contact with komatiitic flows and or contain intercalations of komatiitic flows. Mineralogically, olivine, clinopyroxene, and a glassy to microcrystalline groundmass constitute the main phases of the komatiites, with chromian spinel, orthopyroxene, primary amphibole, plagioclase, and sulfide minerals occurring as accessory phases. The mafic–ultramafic units have undergone serpentinization, chloritization, uralitization, epidotization, silicification, and carbonatization. Pyrite is the most abundant sulfide mineral, accompanied by chalcopyrite, chalcocite, covellite, goethite, and malachite. Geochemical data classify the Fariman komatiites as Al-depleted komatiites, while REE patterns and multi-element spider diagrams indicate a high-degree mantle melting source with minor crustal contamination. Olivine and magmatic chromian spinel chemistry reflect a primitive, Mg-rich magma; however, there is no convincing evidence for extensive sulfide segregation or economic Ni–Cu–(PGE) concentration. Overall, the data suggest that the Fariman komatiitic suite largely belongs to the barren-type komatiites, although the presence of potentially sulfur-rich sediments (e.g., black shales) adjacent to lava flows does not preclude localized and limited mineralization. baxsed on the available evidence, a genetic model involving the ascent of hot, heterogeneous asthenospheric mantle, possibly plume-related, within the subduction-influenced margin of the Paleo-Tethys Ocean is proposed for the formation of the Fariman komatiites. In conclusion, the Fariman area is assessed to have moderate and locally developed exploration potential for komatiite-associated sulfide mineralization. Future exploration efforts should focus on olivine cumulate facies, channelized lava flows, and komatiite–sediment contact zones, which are considered the most prospective targets.
