2. Database Structure

[5]  The relational database "Rare-metal Carbonatites and Diamondiferous Kimberlites of the World'' comprises four tables:

  1. The table of carbonatite ultrabasic alkaline complexes of the world (tabl_karb);

  2. The table of diamondiferous kimberlitic and lamproite massifs of the world (tabl_kimb);

  3. The table deciphering table columns tabl_karb, the abbreviations of parameters (tabl_fieldNames_karb);

  4. The table deciphering table columns tabl_kimb, abbreviations of parameters (tabl_fieldNames_kimb);

[6]  The database section on carbonatites (table tabl_karb) describes 156 global massifs, predominantly related to ore-bearing ultrabasic alkaline complexes with carbonatites of the central type, either incorporated into eight provinces, or confined to middle massifs of the continental shelf. The quantative information on 62 geological parameters of the massifs (for the first time in the world) is presented on the absolute, and in separate cases on the numerical arithmetic scale. The table contains the massifs affiliation to regions, sub-regions and countries and their geographical coordinates. Based on the initial parameters, the interim additive or multiplicative indices were calculated (not mentioned in the database). They were used in the statistical data processing for obtaining a high-quality criteria of the data.

[7]  The database section on 200 global kimberlitic massifs (table tabl_kimb), located in eight regions, includes the data on 43 geological parameters. Geographic location (country), sub-provinces (regions) and kimberlitic fields, geographic coordinates are described. The major part of presented massifs is diamondiferous. In addition to the kimberlitic massifs, the database includes the most explored lamproite complexes and maggavanites. As it was done for carbonatites, various geographical parameters were evaluated either on the absolute or numerical scale. For the contrast expansion of some criteria combined parameters were used: summarized systems of deep and crust faults, controlling kimberlitic fields and massifs; a cumulative structural-morphological index of a massif (a number of feeders, apophyses, sills).
