Abstract

The main object of the study is a large crystalline garnet, which noted in the form of large perfect crystals in both single and druse. The crystals of the pinkish, usually turbid almandine have a value from the pinhead to 7 cm, but preferably from 1-2 mm to 1 cm. In some layers of chloride shales, crystals of the same type usually found. Pomegranate crystals more or less easily separated from the host rock, from slate subjected to some weathering, garnet crystals pour themselves out when the piece of rock destroyed. Garnet crystals found in chlorite schists. The mineral composition of chlorite schists is quite simple and consists mainly of chlorite and fine-grained sericite. The stone crashed in a mechanical mortar to 1 mm, and then a magnetic and electromagnetic separation carted out, followed by the study of each individual fraction under a binocular microscope. The density and micro hardness of the garnet itself determined. For a more detailed study conducted chemical analysis of the mineral and of the breed itself and a diagram of the facial accessory of the mineral created.
