Geophysical model of the Earths crust, geodynamic conditions and prospects for discovering Carlin-type ore deposits in the Arctic zone of the Republic of Sakha (Yakutia). Arctic: ecology and economy, 2020, no. 1(37), pp. 82-94. DOI: 10.25283/2223-4594-2020-1-82-94. (In Russian).


Abstract:

A comparative metallogenic analysis of the geodynamic conditions for the formation of Carlin Type Ore Deposits (CTOD) is performed on the basis of modern geophysical models of the lithosphere of the Verkhoyansk, Nevada and South China metallogenic provinces. The southeastern trend of the CTOD of the Sakindzhi ore area in the Yakutia Arctic zone of the Verkhoyansk province corresponds to the trend of the average density and temperature of the upper mantle. A similar direction is also noted in the structure of the Moho surface. The Nevada and Sakindzhi CTOD and deposits of the Guizhou region (South China) are spatially confined to areas with an average thickness of the earth’s crust (on mantle uplifts or their slopes). The Nevada and Sakyndzhi gold ore deposits are confined to the crustal areas with the smallest thickness of a weakly metamorphosed sedimentary layer, while the pattern is not observed in the location of the South Chinese CTOD. The Nevada and Sakyndzhi deposits are spatially controlled by relatively less dense and warmer sections of the upper mantle. The South Chinese CTOD are localized on the border of the “warmed” and “cooled” region of the upper mantle. The similarity of the geodynamic conditions in the formation of the Nevada and Sakyndzhi CTOD is revealed that confirms high prospects for the discovery of large deposits in this Arctic region of Yakutia. New ore areas with CTOD are forecasted throughout the Chersko-Polousnensky folded belt (Kolyma loop).
