Gazu copper deposit is located in the boundary of Tabas and Lut block, 65km southeast of Tabas and 15km southwest of Deyhouk. The dominant lithology in the area consists of Shotori dolomite and limestone and Shemshak shale and sandstone.  Intrusive rocks with intermediate composition are widespread and numerous in the area. They consist of diorite, monzonite, and quartz monzonite to granite. Mi...

Shurab polymetal ore deposit is located in 77 km south of Ferdows in north of Lut structural zone. Geology of the area includes a Jurassic sedimentary rocks, comprises shale and sandstone of Shemshak Formation, Badamo limestone, and andesite, dacite, rhyodacite and rhyolite volcanic and subvolcanic-calc-alkaline Tertiary rocks as a hydrothermal mineralization host rock. In these rocks, minerali...

In Iran, the most important tin and tungsten mineralization has occurred in Shah-Kuh granitoid pluton (Lut Block, east of Iran), and Nezamabad area (Boroujerd granitoid complex, west of Iran), respectively. Both mineralizations are mainly accompanied by existence of quartz- tourmaline veins. Nezamabad veins- type tourmalines have dravite composition and have been formed in hydrothermal conditio...

The Zaraj-Sou bauxite deposit (southwest of Ramsar, Mazandaran Province, northern Iran) was developed as discontinuous stratified layers and/or lenses along the boundary between carbonate rocks of the Elika (Triassic) and shales and sandstones of the Shemshak (Lower Jurassic) formations. Diaspore, kaolinite, hematite, and anatase are the major mineral phases of the ores. Texturally, the bauxite...

Kishan lead-zinc deposit is one of the Malayer-Esfahan metallogenic belt deposits, located NW Arak, Markazi Province. The fluid inclusion microthermometry of the primary liquid-vapor bearing fluid inclusions trapped in the cogenetic quartz veins exhibited a homogenization temperature ranges from 140 and 272 °C (average 208.47 °C from 68 fluid inclusions), corresponding with the salinity of 10 t...

Freezi Lead- Zinc- Copper prospect area is located in north east Mashhad in Khorassan Razavi Province. Mineralization was formed in the area as vein type in the host rocks of slate with interlayer of phyllite and meta sandstone of Upper Triassic to Early Jurassic age (equivalent to Shemshak Formation). The only alteration in the host rock is silicification. Primary minerals are quartz, galena, ...

Erodibility of basin formations is depends on their resistance versus of erosion. In a basin are not the same stones, their resistance and covering area. Obviously, formations sensitivity versus of erosion are determining rate of sediment production in a river. In this research has been analysis formation erodibility versus of erosion in the Sajjadrud basin. Research methods are descriptive–ana...

Palang Dar gabbrodioritic intrusion cropped out in about 30 Km NE of Damghan in the eastern part of the Alborz structural unit. In this area a few small-scale gabbrodioritic intrusions and diabasic dikes with Middle Jurassic age intruded into shale, sandstones and limestones of Shemshak Formation. Emplacement of this intrusion into host rocks are associated with contact metamorphism and formati...
