Characteristic of density distribution along latitudinal fault zones and estimated profiles has been given. Possibility has been found of north-south inclination of each of latitudinal fault zones. Criteria of selection of promising areas for the search of kimberlites and lamproites have been determined. Within the limits of the USh and DDD two types of such areas specific by their features have been selected. Confinement of predicted areas for the search of kimberlites and lamproites to a certain type of material composition of the crust (mainly diorite) has been revealed. It has been found that ore fields and the areas in the western part of the USh are situated above the areas of development of crustal-mantle mixture and are mainly the blocks of leuko-basaltic type, and in the eastern part they are specified by the absence of crustal-mantle mixture and are confined to blocks of diorite type of the material composition of crust.
