Volkova T. Geological-geochemical criterions of forcasting estimation of rare-metallic ore-grade minaralization tion into alkaline complexes of Priazovskiy block (Ukrainian Shield).

Object of a research - perspective rare-metallic objects of of Priazovskiy blockThe purpose of work - development and theoretical basis of methodology of searches and forecasting estimation of rare-metallic ore-grade minaralization. The researches were conducted with use of a mathematical statistical methods for the computer treatment of prospecting and searching data, metal-logenic, informatic and synergetic analysis, geological-geochemical mapping with use geoinformatical system. The scientific significance of work consists in creating of theoretical basis of connection between rare-metallic ore-grade minaralization and intensivity of processes of differentiation and separation of ore substance, allocating mineralization control structures of a different rank and the most perspective rare-metallic objects of Priazovskiy block, evaluating their resources. The practical significance of work consists in work out of geological-geochemical criterions of forecasting estimation of rare-metallic ore-grademinaralization, inculcating parameter for evaluating of resources of perspective rare-metallic objects. The outcome of researches has introduced by Priazovskiy expedition during of searching in October and Volodar squares, prospecting Azovskiy and Mazurovskiy deposits.
