Bibliographic description: Chizhova I.A., Lobanov K.V., Volkov A.V. Logical and information models for forecast and rapid assessment of new gold deposits in the Arctic zone of Russia. Arctic: ecology and economy, 2019, no. 4(36), pp. 107-117. DOI: 10.25283/2223-4594-2019-4-107-117. (In Russian).


Abstract:

Logical and information models were developed based on a wide range of elements and a representative database (DB) for 95 gold deposits and gold occurrences in the North-East of Russia. As a result of the calculation, the elemental logical and information models for each ore-informational type were obtained: Au-Ag-epithermal; Au-quartz; Au-sulfide; Cu-Mo-Au porphyry; pyrite-polymetallic, enriched with Au and Ag. The rules were developed that made it possible to reliably identify the samples (43 errors out of 289 samples, recognition quality = 0.85). It is shown that developed models can be used to forecast and evaluate new gold deposits in the Arctic zone of Russia.
