ABSTRACT
Because of wide industry technological requirements to quality of nonmetallic raw materials it is necessary to develop of deposit in accordance with the map of industrial grades minerals distribution. Eventually, the distribution of useful components and harmful impurities are defined by the geological genetic processes which formed the deposit. We tested the industrial grade distribution by means of the spatial and statistical analysis on the Jelenovskyi field of carbonate raw materials. It is established that essential distinction of quality on every stratigraphie horizon is connected with intensity of secondary geological processes. The complex grade index is constructed on the basis of significant correlations between separate quality indicators. The development of the field is carried out according to the map of complex grade index for various consumers of raw materials. So the geological causes of spatial distribution of industrial grades is a key to improvement technology of field exploitation.
