Abstract

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

Rocks of the Gabriel mine (East Kazakhstan) belong to intensively modified milonites. These rocks in the Ore Altai are often ore-bearing for metals such as zinc, lead, copper and gold. Milonites are formed by imposing deformations on the original rocks. These rocks are interesting for large studies. Using the EBSD method allows us to investigate the deformation stage of mineral formation more detailed. In this work, we studied sections of quartz porphyroblasts with different volume fractions of pyrite. As a result, we determined the influence of the pyrite volume fraction on the degree of quartz deformation and the possible presence of water in the later stages of mineral.Rocks of the Gabriel mine (East Kazakhstan) belong to intensively modified milonites.
