Geological-and-structural 3-D modelling of Serhiivka complex Au-Mo deposit (Ukrainian Shield)

Serhiivka gold-molybdenum deposit is located in the southern part of the Solone ore field situated within Sura greenstone structure (greenstone belt) of Middle Dnipro Archean craton of Ukrainian Shield. The deposit consists of Mezoarchean (3,0-2,9 Ga) tholeiitic basalts and gabbro-dolerites metamorphosed at green-shiest facies, which are intruded by submeriodional Serhiivka subvolcanic body with associated dikes of dacites and rhyodacites. Gold-rich ore bodies, as well as molybdenum mineralization are predominantly found in metabasalts and metagabbro-dolerites, and locally, in felsic rocks that are treated to be the sources of ore-bearing fluids. 3-D modelling carried out has revealed some features of geological structure and distribution patterns of gold mineralization that are typical of the central part of the Serhiivka deposit. These features can be used while interpreting the geological structure of the deposit, as a whole, as well as distribution pattern of gold and molybdenum mineralization. It can result in rising of evaluation accuracy of ore reserves and will increase investment appeal of the complex gold-molybdenum Serhiivka deposit.
