The anisotropy of deformation and strength behavior in quartz mica schist is fundamental to rock mechanics. Here, we concentrated on the practical application numerical simulation rock. First, existence engineering was reported, tested situ, analyzed. Then, a set specially designed multi-angle uniaxial compression tests conducted. Based these, two methods (explicit implicit) for were demonstrat...

In the Asemi-gawa area of intermediate high-pressure and low-temperature Sanbagawa metamorphic belt in central Shikoku, Japan, piemontite-quartz schists are common in which cation exchange between piemontite and garnet has been studied. Piemontite in contact with garnet usually contains two zones in which core is enriched in Mn3+ and surrounded by a rim rich in Fe3+. Garnet is Ca-Fe-bearing spe...

Quartz inclusion thermobarometry utilizes the pressureand temperature-sensitive Raman peak shifts of quartz inclusions in garnet to determine formation pressure and temperature (PT) conditions. The measured Raman shift indicates the pressure currently retained in the inclusions at ambient external conditions, such that entrapment PT conditions (i.e., P and T of garnet growth) can be determined ...

The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...

The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations rocks Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions green schist facies. mineralized zones site are confined to narrow faults in tectonic northeast and northwest directions. main form manifestation gold-bearing small steeply dipping veins, len...

Wolfram mineralization in the area of Vau village (Dong Giang district, Quang Nam province) is distributed along small stream together with other sulfide mineralizations form to large boulders. Ore minerals are mainly sheelite, pyrhotite, arsenopyrite a little chalcopyrite and pyrite. The ore stockwork type gray, light gray metamorphic sedimentary rocks quartz - mica composition alternated feld...
