“Carbonatites and Kimberlites of the World” Database and Geoinformation System: Experience of Creation and Use for Solving Geological Tasks

The article gives an overview of experience of the information database creation about the “Carbonatites and kimberlites of the World” and use of GIS technology. On this basis, the tendencies of ultrabasic alkaline massifs evolution with rare metal carbonatites, diamondiferous kimberlites and also criteria of prognostic estimations for rare metal and diamond deposits are revealed. As a whole, from older to younger epochs mineragenic evolution had the following image: (Nb→TR→P→Fe). Carbonatites are located mainly along the axis or active margins of such rift zones—“hot lines”. On the contrary, the largest manifestation of the kimberlite massifs is at a great distance from the rift zones. All these investigations became the basis for the new prospecting strategy in Russia and can be used in different regions of the World.
