Abstract
The scope of the studies embraces statistical and mechanical properties of surface of different kind crystals of salt rocks. Fractal dimension, hardness and elasticity moduli of such crystals are determined. The article gives estimates of fracture toughness and wettability of salt rock crystals as function of fractal dimension of the crystal surface microrelief.
