The study area is situated within the Lut Block 50 Km northeast of Ferdows. The oldest exposed rocks are Cretaceous limestone. Kerman conglomerate cover the limestone. Dacite-rhyodacite lava and pyroclastic rocks erupted over Kerman conglomerate.  Volcanic activities took place at different time in Tertiary. The composition ranges between trachyandesite, andesite, andesite-basalt and rhyolitic tuff. Sub-volcanic diorite, monzodiorite, monzonite, quartz monzonite and granite porphyry intruded the volcanic rocks during Oligo-Miocene time.  Both volcanic and intrusive rocks are K-rich calc-alkaline to shoshonitic. Intrusive rocks (except granite porphyry) are I-type granite and belong to magnetite series. The pattern of spider diagrams both volcanic and intrusive rocks are similar. In comparison with mantle, They are enriched in Cs, K, Rb, La and Zr and depleted in Ba, P and Ti. Two groups of alteration zones are recognized: 1- silicified assemblages (silica-sericite-propylitic, silica-propylitic & silica- sericite). This group is related to granitic magma. 2- propylitic-sericitic-argillic group which are associated with monzonite, quartz monzonite-diorite intrusive rocks. Mineralization associated with granite porphyry show Mo, Ag, Pb and Zn anomalies. Mineralization associated with monzonite, quartz monzonite-diorite show signs of porphyry copper. They have Cu, Au, Pb and Zn geochemical anomalies.

The study area is located at northeast of Neyshabour in the Khorasan Razavi Province, northwest Arghash Gold Mine. The rocks of area are composed of polutonic to subvolcanic units with acid- intermediate in composition. They consist of granodiorite, diorite and granite. Alteration zones are: propylitic, sericitic, silicified and argillic. In the study area, mineralization is divided into two types: primary and secondary .The Primary mineralization consists of disseminated type in intrusive bodies (syngentic) and vein-type mineralization in fault zones (epygentic). Pyrite is recognized in dioritic and granitic intrusive as disseminated.The vein- type mineralization consists of chalcopyrite, pyrite, quartz and calcite minerals which are related to NE-SW, NW-SE, E-W fault zones dipping 60 degree. Secondary minerals in the study area are malachite, azurite, hematite, goethite and covellite. Geochemical study in the area shows anomalies for Cu, Pb and Zn in primery and secondary geochemistry halos. High concentration of Cu, Zn and Pb in stream sediments samples are 124, 85 and 38  ppm and in rock samples are 2200, 336 and 589 ppm respectively. Based on present of disseminated mineralization in the surface and undersurface Arghash area, present of vein-type mineralization Au and Sb in the arghash area and present of vein-type mineralization in the fault Zone in the study area, present of geochemistry halos for Cu, Zn, Pb in the study ares and surrounded, probably Arghash area can be vein-type mineralization ralatad to copper porphyry system in this area. 

Keybarkuh is located about 70 Km southwest of Khaf city (Khorasan Razavi Province) in the northeast of the Lut block. Rock units in the area comprises of slate, phyllite, schist and recrystalized limestone with Paleozoic age that was intruded by granite to diorite as dikes and stocks of Cretaceous to Tertiary age. Based on magnetic susceptibility, intrusive bodies are oxidant and reducing which the oxidant bodies mostly having alteration and mineralization. The eastern Keybarkuh oxidant bodies are of Midlle Eocen, related to subduction environment of continental margin, often high-K to shoshonitic and metaluminous. Propylitic alteration zones with broader area and sericitic, argillic and silicic with less distribution were observed in the southern area. Mineralization is seen in the contact of intrusive bodies or in joint and fractures of them as veins and veinlets in south of the area. Veins and veinlets with northwest to southeast strike, 70 to 80 degrees dip to the northeast have thickness upto half meter. They can be divided into two sets: 1-Veins and veinlets associated with galena, sphalerite and barite as primary minerals, which formed the first generation of mineralization. 2- Veins and veinlets associated with pyrite, chalcopyrite and quartz as primary minerals; covellite, bornite, chalcocite, malachite, azurite and iron oxides (magnetite, hematite and limonite) as secondary minerals which is the second generation of mineralization. Paragenetic sequences of minerals and relationship between minerals are indicative of a hydrothermal activity and deposition of the above mentioned minerals in at least two stages in the upper part of oxidant intrusive bodies. Geochemical exploration of stream sediment show anomalous Cu (68 ppm), lead (1691 ppm), zinc (320 ppm), barium (5003 ppm) and the rock also show anomalous Cu (3%), gold (2657 ppb), silver (ppm 160), lead (4%), zinc (2159 ppm), barium (1466 ppm) bismuth (1767 ppm) and Mo (66 ppm) in the southern parts of the area which are relatively high.
