7. Conclusion

[29]  Summing up we can assume that to date the portal "Geophysics'' of GC RAS is an important component of the systems of portals "Electronic Earth''. The data resources and algorithms, presented in the portal, are diverse and extensive. Their correct application allows to solve complicated and resource-consuming tasks, which is shown by the example of the database "Carbonatites and Kimberlitic Massifs of the World''.

[30]  The system analysis of this database has provided the evidence that a complex joint application of tectonic, age and structural criteria is highly efficient for analysis of mineragenic evolution and prognostic evaluation of the entire set of carbonatite and kimberlitic complexes, fields, regions and provinces. A necessary requirement of evaluation of data criteria is the statistical analysis of their interaction and integral character of their relation to mineralization of various information factors. Information content of criteria depends on a range of objects of prognostic evaluation: regional-tectonic factors to a great extent determine the productivity of large fields and sub-provinces; local structural parameters determine the mineralization of massifs; parameters of the mineral and chemical structure can serve as the criteria of ore content of separate phases of massifs.

[31]  Therefore a complicated and resource-consuming geoinformation task was solved with the help of the project "Electronic Earth''. It was devoted to the analysis of the magmatic and mineragenic evolution and productivity factors of rare-metal carbonatites and diamondiferous kimberlites. Principally new mineragenic conclusions were made according to the rules of manifestation in the lithosphere of the given types of the mantle magmatism and related diverse minerals, important interrelations were revealed between different parameters and ore-bearing characteristics of rare-metal carbonatites and diamondiferous kimberlites and the traditional strategy of predicting, searching and evaluating complex (Nb, Ta, TR, P, Fe, Ti, Zr) carbonatite and diamondiferous kimberlitic deposits was significantly amplified.
