Bibliographic description: Bochneva, A.A., Lalomov, A.V. On the issue of the sources of alluvial diamonds of the Ebelyakhsky region (Arctic zone of Russia). Arktika: ekologiya i ekonomika. [Arctic: Ecology and Economy], 2022, vol. 12, no. 2, pp. 235-245. DOI: 10.25283/2223-4594-2022-2-235-245. (In Russian).


Abstract:

The work considers the identification of potentially diamond areas based on the geological and statistical analysis of data from heavy mineral concentrate sampling of alluvial deposits of the Ebelakh River and its confluents. The researchers compress the information of the diamond placer mineral field of the Ebelyakh River and identify the main components based on information entropy (K. Shannon). The spatial heterogeneity of polymineral fields, revealed using the entropy method, allow outlining areas of possible localization of intermediate hosts (or their former development) in the Ebelyakhskiy region.
