THE MICRORELIEF RESEARCH (FRACTAL PROPERTIES) OF THE SURFACE OF CRYSTALS OF BASALT ROCKS OF THE KYZYL-KII DEPOSIT OF KR

Abstract

The surface properties of the microrelief of crystals of basalt rocks of the Kyzyl-Kiya deposit of the Kyrgyz Republic were studied. The study of the microrelief of the surface of basaltic rock crystals was carried out on the basis of determining the fractal dimension. Using a microscope coupled with a computer, the surface of crystal samples was scanned, and for each type of crystal, several characteristic areas of a basalt rock crystal were studied. Estimates of the index of crack resistance of basalt rocks depending on the fractal dimension of the surface microrelief have been carried out. To determine the fractal dimension D, the image of the basalt crystal surface was divided into many cells and the number of occupied cells was counted, then the cell size increased, we repeated the steps of the previous step, and the resulting dependence of the number of occupied cells on the cell size was used to determine the values of the fractality index and then the fractal dimension.
