Siliciclastic sediments of the Cheleken Series (Lower to Middle Pliocene) are exposed along the northern flank of Elburz Mountain Range. The goal of this study is to identify the clay mineral type in these siliciclastic sediments in Mazandaran and Golestan regions, because this can help in the prediction of drilling mud type that can be used. 23 samples have been collected from Neka, south of G...

Water purification is a vital and essential thing for human life. The presence of pollutants in water is a major threat to the environment and human health. Various materials have been proposed and used for water treatment in recent years. Recent research has shown the potential of two-dimensional materials such as graphene oxide and its composites for water purification. The goal of this proje...

Quaternary loess and loess like deposits covered more than 3200 km2 of Golestan Province. Mineralogical aspects of loess deposits were studied on collected samples with east-west trend by random method using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDXA). The results showed the presence of quartz, calcite and clay minerals like illite and...

Geologically, Shahr-e-Babak playa is located in the southeast of Sanandaj-Sirjan Zone. Based on mineralogical and scanning electron microscopy (SEM) studies, in the studied playa major mineralogical phases include hallosit, kaolinite, illite, quartz, calcite and gypsum. Based on geochemical data, the average aluminum oxide values is 13/93% , silicon oxide is 39/53% and the average of volatiles ...

The ruins of impressive structure made by adobe known as the city of “Belgheis” is located 3 km from Esfarayen in the province of North Khorasan of Iran. The role of soil quality in the occurrence of damages to clay and adobe structures of Belqis area is the purpose of this research. Choosing the right soil is the first step in the preparation of adobe, Therefore, it is necessary to study the r...

Mineralogical and geochemical investigations indicate two general stages of skarnification i.e, prograde and retrograde stages in the Mohammad-Abad district, south west of Yazd province. Metasomatic skarn (Prograde stage) occurred with precipitation of anhydrous calc-silicate mineral assemblages (andradite and diopside- hedenbergite) within the temperature ranges of 470 to 550 ºC. During the re...
