Principal Skarn deposits along the northern margin of the Ahar batholith from west to east include Mazraeh, Vine and Gowdoul skarn deposits. Among these skarn deposits, the Mazraeh Cu-Fe Skarn deposit is the most typical skarn deposit in the NW Iran. This skarn deposit is located 5 km. north of Mazraeh village and 20 km north of Ahar town. The origin and development of the skarn can be related ...
Nodoushan clay deposit is located about 130km southwest of Yazd city in the Uromieh-Dokhtar volcano-plutonic belt. Based on the field, mineralogical and geochemical studies, the rocks of Nodoushan area are of volcanic type and are composed of dacite, andesite and olivine-basalt, the pyroclastic type (crystalline tuff), and the microgranodioritic intrusive rocks. According to Zr/TiO2 versus SiO2...
Permeability and seismic velocity anisotropy across a ductile–brittle fault zone in crystalline rock
In this paper, according to the density functional theory and semiharmonic approximation and solving kohen's equations using plane wave, band structure, phonon scattering; Dielectric tensor, Bourne effective charge, Raman cross-section; We calculated the infrared and specific heat capacity of indium phosphide in two-phase structures on zincblend (ZB) and salt rock (Rs). The results show that t...
