The Sebandoon copper deposit is located in the northern part of the Sabzevar subzone. The rock units exposed in the area consist of upper Cretaceous volcano-sedimentary sequences of trachyte, trachyandesite, basalt, split, shale, dacite and sandstone. The Sebandoon native copper deposit comprises stratabound mineralization which is hosted in split basalt. The main ore structures and textures in the deposit include disseminate, veinlets, open space filling and replacement forms. The ore mineral assemblages are simple and consist of native copper, coprite and malachite and main gang minerals are zeolite, calcite, quartz, chlorite and epidote. Fluid inclusion studies on ore-bearing zeolite reveal that majority of primary inclusions are liquid-rich two-phase (LV) ones. The studies indicate homogenization temperatures were between 228 and 340°C and salinity varied between 0.6 to 5.7 wt% NaCl eq. Based on the evidence from geology, mineralogy, alteration, fluid inclusion, and geodynamic environment, the Sebandoon copper deposit is similar to Michigan copper type deposits, in which copper was leached from the basaltic rocks during burial metamorphism and the ore-forming fluids moved upwards and subsequently deposited as native copper due to low pressure and mixing with meteoric fluids.

The Manto-type copper deposits of the Qom-Saveh region are located in the central part of the Urumieh-Dokhtar magmatic arc and occurred in the Eocene volcano-sedimentary sequence. The most important deposits in the studied area are East Narbaghi, Khankishi, Veshnaveh, and Kahak. The geometry of mineralization is stratabound and hosted in the silty tuff, tuff breccia, andesite, lithic crystal tuff, and amygdaloidal andesite basalt. The hypogene ore minerals include chalcocite, bornite, and minor chalcopyrite with vein-veinlet, open space filling, disseminated, and replacement textures. Based on geological studies, two major stages are distinguished for hypogene mineralization. Disseminated and framboidal pyrite formed during the first stage of mineralization which occurred simultaneously with volcanism, sedimentation, and early diagenesis. The second stage of mineralization took place during late diagenesis when copper-bearing oxidized fluids entered into the reduced pyrite-bearing host rock, causing the replacement of the first stage pyrites by copper sulfides. The sulfur isotope composition of sulfide minerals from the East Narbaghi deposit varying from -10.2 to -4.4 ‰ (averaging -6.7 ‰VCDT) indicates the presence of a reduced environment resulting from activation of sulfate-reducing bacteria. The geology, ore mineralogy, alteration characteristics, and sulfur isotopic compositions suggest that the studied ore deposits may be classified as Manto-type mineralization.
