- Аннотация: The morphological analysis of mineral grains was conducted by image processing obtained by miscellaneous methods of a microscopy. The software is based on a method of identification of objects’ boundary with the help of approximating by straight lines and allows to determine main specifications of the grains form. The profile factors distribution of the oblongness, and roundness, estimated by program, has coincided with distribution of a cryogenic destruction parameter obtained by mineralogical method. The maximum of an expansion of flat surfaces, calculated by the program, are dated for top and bottom parts of a profile. This coincides with the micromorphological data of predominance of single splittings and derivation of the extended forms of particles in the upper horizons and secondary predominance of isomeric grains when decreasing of the particles sizes in the lower.
