In order to explore probable blind mineralized zones of the Aliabad deposit, it is necessary to evaluate the element concentrations towards depth or margins of the deposit. Modelling primary geochemical haloes could be useful in this stage. Ore bodies at the Aliabad deposit are primarily controlled by structural features, which provide an opportunity to investigate the zonality in primary halos...

Mahour polymetal deposit located west of Nehbandan, east-central Iran, formed in hypabyssal acid rocks. Mineralization occurs along a three-km-long vein. Three zones have observed in the ore, downward: 1) leached zone marked by malachite, azurite, hematite, goethite and limonite, 2) supergene zone characterized by bornite, covellite, and chalcocite, and 3) Hypogene zone containing magnetite, ch...

The Argash antimony ore deposit is located at south of Neyshabour and the eastern part of the Sabzevar zone. This deposit occurs within a sequence of Eocene-Oligocene volcanic-intrusion rocks. The mineralization occurs as open space filling, taking place as irregular veins, veinlets and hydrothermal breccias. The mineralogy of the veins is comparatively simple. The primary antimony-bearing mine...

Shurchah antimony deposit is located in flysch zone of eastern Iran. The antimony mineralization was formed in silicic veins that hosted by highly silicified and brecciated granitoids and low-grade metamorphic rocks which are rich in phyllosilicate minerals. Stibnite is the most aboundant Sb-bearing ore mineral in the veins and is associated with pyrite, chalcopyrite, arsenopyrite and gold. Sen...

Some Fe and Fe-Mn deposits are found within sedimentary pelagic rocks and radiolarian cherts of the Khoy ophiolite. Mn-Fe mineralizations in Safo area north of Chalderan City are examples of them. In Safo area, deposition of manganese occurred as lense-like orebodies in different horizons within pelagic rocks. They are stratiform and have syn-sedimentary origin. Mineralogically, braunite, pyrol...
