Rasht Abad Cu±Au deposit is a part of the Tarom-Hashtjin metallogenic belt in the western Alborz-Azerbaijan zone. The exposed units in the area include volcanic, sub-volcanic calc-alkaline to shoshonitic rocks with Upper Eocene age and belongs to magmatic arcs setting. The most important alterations related to mineralization include low temperature silicification and sericitic alterations. Mineralization with quartz-sulfide veins in the area consist of a series of oxide (hematite), sulfide (chalcopyrite, galena, bornite, covelite), sulfate (barite) and carbonate (malachite, azurite). Fluid inclusions measurements on primary two-phase L+V inclusions determined homogenization temperatures between 138 to 320°C (229°C) and salinity between 2.49 to 9.41wt% (9.41) NaCl eq, evidence of isothermal mixing and dilution. The δ¹³C (-9.21to -6.81‰) and δ¹⁸O (-14 to -15‰) also show the influence of meteoric waters in late carbonate veins. The results of this study show that the high similarity between Rasht Abad and intermediate sulfidation epithermal deposits.

The Pillow lava and diabase dykes of the southwestern region of Aleshtar are host different species of zeolites and secondary minerals. Zeolites are formed by the cavities and veins and decomposed from primary minerals. Based on field studies, X-ray diffraction (XRD) and Electron Microprobe Analysis (EPMA), natrolite zeolites (most abundant zeolites), mesolite, scolecite and analcime have been identified in the pillow lava and diabase dykes in the study area. The average Si/Al ratios for natrolite, mesolite, scolecite and analcim are 1.46, 1.49, 1.62 and 2.29, respectively. These zeolites are formed during two stages of metamorphic hydrothermal fluids, during fractures and in the cavities of host rocks and at temperatures below 250 °C. The investigation of the geochemical properties of zeolites host rocks, shows that their magmatic series is calc-alkaline to tholeiitic and their tectonic environment depends on the mid-ocean ridges (MORB).

For the first time in 2001, demantoid garnet from Iran was discovered in Kerman province and in Sanandaj- Sirjan geological zone. The host rock of these demantoids is the serpentinized peridotite rocks of the Haji Abad ophiolite (Esfandagheh). It has gemological features including regular crystalline shape, greenish yellow to dark green color, the refractive index of 1.80 to 1.82, and a specific gravity of 3.81 to 3.83. The electron microscope images of these samples indicate that the chromium element is the color agent. Inclusions in gemstones are an important indicator of the nature of a stone and may, additionally, be a characteristic feature of a particular origin. Also, the study of the microscopic features of this garnet demantoids, including the presence of needle inclusions and horsetail in them, confirms the serpentine host stone for them. The results of chemical analysis by SEM show that the O, C, Fe, Ca, Si, Mg and Al elements are the components main elements of the studied garnets. The Raman spectra of the analyzed studied samples, showed compatibility with demantoid reference spectrum. Also, according to the studies, it can be said that the southern Kerman demantoids like the Russian, Italian and Pakistan garnets, have the Serpentine origin.
