The main aspects of regional development of the mineral base of Ukraine are defined. The structure of regional development of the mineral base of Ukraine was investigated by grouping administrative and territorial units by the activity of subsoil work, by the degree of industrial development of available proven reserves of minerals, by quantity and type, by the presence of strategically important minerals. It is established that balanced development of the mineral base of individual regions is complicated by the uneven distribution of studied and forecast mineral resources within the limits of separate territories, as well as the peculiarities of distribution of consumers of mineral raw materials. The main disadvantages in the regional structure of the mineral base were identified and the main directions of their optimization were determined in order to achieve balanced development indicators. The state of national programs development of mineral base of Ukraine for period to 2010 and 2030 was adopted for the balanced development of Ukraine’s mineral base. But this program does not include the issue of the regional nature of the development of a mineral base in the conditions of decentralization, which is provided for by the Concept of reforming local self-government and territorial organization of power in Ukraine. The study of official sites of regions, cities and united communities showed a systematic absence of official regional development programs for the mineral resource base.

The results of the analysis of experimental data concerning the sound absorption in the nitromethane--pentanol and nitrobenzene--hexane solutions obtained in a wide frequency interval of 5-2800 MHz and measured along the isotherms and isoconcentrates, including their critical values, are presented. The detected anomalous dependences of the sound absorption coefficient were found to obey the laws of the dynamic scaling theory only in the fluctuation region of the problem parameters, fl ≫ 1. The sound frequency growth ( ≥ 110 MHz) in the examined frequency interval, as well as moving away from the critical temperature and concentration values, is proved to transit the system from the critical region into the crossover, fl ∼ 1, or even hydrodynamic, fl ≪ 1, one. K e y w o r d s: sound absorption coefficient, critical stratification point, binary solution, concentration fluctuations, acoustic relaxation.
