Estimating gold-ore mineralization potential within Topolninsk ore field (Gorny Altai) [PDF]
, 2015 Based on the results of ore and near-ore metasomatite composition analysis, the factors and indicators of gold-ore mineralization potential were proposed. Integration of the obtained data made it possible to outline magmatic, structural, and lithological
