The presence of water in the structure of quartz and the deformation features of plagioclases of the Gabriel mine.

The authors of the article studied the deformation features of quartz (SiO2) and pyrite (FeS2) in the rocks of the Gabriel mine, earlier. The presence of water in quartz is confirmed in this work. In addition, the deformation features of plagioclase ((Ca, Na) [AlSi3O8]) and its chemical composition are studied. Fragile deformations in the region of double boundaries of plagioclase have not only a chemical composition, but also a tensor nature. [ABSTRACT FROM AUTHOR]
