Neyzar iron deposit is located about 50 km southwest Mashhad, northeast Iran. It was developed as layered and discontinuous lenses in a fault zone within quartz-arenite and sub-litharenite sandstones of Lalun Formation (Lower Cambrian).  Mineralographical studies show that hematite is the principal iron ore mineral accompanied by goethite and lesser amounts of pyrite. Microscopic examinations c...

The Hatamabad prospect area is located in northeast of Qaen, South Khorasan Province and in northeast of Lut block. The geology of area consists of volcanic rocks with basalt- andesite composition and sedimentary sequences (mudstone, limestone, and conglomerate) with Paleocene-Eocene age that monzodioritic dikes were intruded in them. Monzodioritic dikes have high-k calc-alkaline and metalumino...

Deylaman area lies on Paleogene volcanic rocks in Western Alborz near the border between Central and Western Alborz structural zones. The succession of Paleogene rocks in the area is comprised of three separate phases each of which representing one stage of volcanic events. The main purpose of this paper is to study the lithologic sequence and geochemical characteristics of phase two volcanic r...

Intrusion of granodioritic and quartz-dioritic igneous bodies of the Oligocene age into andesitic rocks with the Eocene age resulted in occurrence of widespread argillic alteration zone in the Asbkhan area of Heris (East Azerbaijan Province, NW Iran). A significant portion of this system formed the argillic alteration zone. Based on mineralogical examinations, kaolinite, quartz, smectite, aluni...

The Cheheltan Mountain is located at south west of Bardsir, Kerman Province. It represents a part of the Eocene Hezar volcanic complex (Urumiyeh-Dokhtar volcanic belt) and consists of lava flows, pyroclastics, epiclastics and numerous intrusions. The lava flows comprise of basaltic-andesites and basalts and contain plagioclase and pyroxene phenocrysts that set in a vitreous or fine-grained matr...

The Kuh-e Mish plutonic complex (KPC) is located about 30 km south of Sabzevar. Based on tectonic division, it is part of Sabzevar zone. The Stratigraphic units of the area are conglomerate, tuff, and sandstone of the Paleogene, radiolarites, andesite and tuff unit of Upper Cretaceous. This collection consists of two plutonic rocks types. (1): The granitoid complex of northern Kuh-e Mish which ...

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 ...
