The ore bodies of Galali and Baba-Ali are two relatively important iron ore deposits in west Iran. These ore deposits are situated in the Sanandaj-Sirjan zone. The deposits are associated with ultramafic, calc-alkaline, carbonatite and other rocks. Macroscopic observations, on the boreholes, show that one of the rare ultramafic rocks (hornblendite) appears in all various horizons parallel to m...
The specific hydrogeoecological conditions of aquifers some technogenic formations, mainly iron ore skarn-magnetite and titanium-magnetite are considered. resulting wastes, which stored in waste disposal sites during development deposits, due to the impact a number factors (natural technogenic) form waters. Waste facilities complex engineering structures (dumps sludge storages), turn create the...
The vein-type mineralization of the base (Zn, Pb, and Cu) and precious metals (Au) in the Qarah Changel area (northwest of Qazvin) is located in the southern part of the Tarom-Hashtjin metallogenic belt. Volcanic (trachy-andesite, rhyolite and dacite) and pyroclastic (tuff, tuffite and tuffaceous shale) (Eocene) rocks are the hosts of this mineralization. Distinctive alterations around minerali...
The trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. A very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. These elements may be concentrated in non-magnetic and magnetic part of calcrete. Based on the current research, mineralogica...

The study area is located in the east of Ahar town in Eastern Azerbaijan Province and is part of the Ahar-Arasbaran Cenozoic magmatic belt of NW Iran. The geological units of the Eocene age are volcanic rocks with andesite, latite - andesite and basaltic andesite composition. Khankandi and Useflu Oligocene intrusive bodies intruded in the volcanic rocks and caused widespread alteration and copp...
The transition zone between the Archean blocks, Jequié and Itabuna-Salvador-Curaçá, in county of Laje, Bahia, Brazil, is potentially important for iron ore deposits economic interest. This research investigates one eighteen anomalies defined by a previous integrated interpretation geological airborne gamma ray spectrometry magnetic data this zone. Its choice resulted from being located an area ...
Anomaly XVI-B located in Central Iran Structural Zone. The oldest rock formations in this study area are related to metamorphic rocks which are included gneiss, micaschist, amphibolite and megmatite. Mineralized intruded mass distinguished by alkaline diorite-syenite that cut Bonoshorow metamorphic complex and limestone units. Metallic mineralization is occurred in syenite, gabbro and skarn roc...
