The research aims to assess the geothermal potential and provide a better understanding of geology geophysics area. study utilizes various methods, including geological mapping, geochemical analysis, magnetic electromagnetic data gain insights into subsurface structures characteristics system. area can be divided three geomorphological units: Alluvial Plain Unit, Near Plains Isolated Hill Unit....
The evaluation of nano-particle based products to protect granite surfaces from water income is presented in this paper. Wettability, water absorption, drying behaviour and water vapour transfer were considered as the most relevant parameters for this evaluation. The effect of the application methods on the final performance was also tested. The results allow to consider that nanostructured pro...
Two methods using nujol and hexachloro-butadiene mulls are described to analyse the water content of powdered granite samples. The nujol mull analyses were carried out on a Unicam SP Ioo spectrometer using the silica content of the rock as an internal standard. The hexachlorobutadiene mull analyses were done by a twin-path Unicam SP 2oo spectrometer, using hexachlorobutadiene as the internal st...

The Zhashui-Shanyang ore cluster area is one of the most important gold polymetallic ones in northwestern China. Qinglingou deposit a newly discovered small-scale area. Gold mineralization closely related to acid intrusive rocks has been found for first time this In paper, geochronology, whole-rock geochemistry, and isotope signature granite porphyries are studied. They characterized by variabl...
At low temperatures (<750 °C at moderate to high crustal pressures), the production of suffi cient melt to reach the melt connectivity transition (~7 vol%), enabling melt drainage, requires an infl ux of aqueous fl uid along structurally controlled pathways or recycling of fl uid via migration of melt and exsolution during crystallization. At higher temperatures, melting occurs by fl uid-absent...
The study area (Bornaward granite) is located in northeast of Iran (Khorasan Razavi province), about 280 km southwest of Mashhad city. Taknar zone is an exotic block, bordered by two major faults, Great Kavir fault (Drouneh) to the south and Rivash fault in the north. A complex of granite, granodiorite, monzonite and diorite crop out at the center of Taknar zone. They are named as “Bornaward gr...
Primary tin deposits usually contain little or no copper due to the distinct geochemistry of Sn and Cu. However, examples copper-rich in many provinces around world are also well known. The genesis remains controversial. Maodeng Sn-Cu polymetallic, a typical Cu-rich deposit southern Great Xing’an Range (SGXR) Northeast China, offers an excellent opportunity reveal coupled copper-tin deposits. o...
