Dyshchuk M. Regularity of gold localization within the Sergiivske deposit, Middle Pridneprovie.

The thesis is dedicated to the evidence of polychronicle genesis of the Sergiivske deposit that has stipulated spatial adjustment of different industrial ore types by finding-out of legitimacies of their localization. General geological position of the deposit within Surska granite-greenstone structure is reviewed. The main geologic features of the deposit are determined. They are the following: structure and composition of ore-bearing strata, metasomatic alteration of rocks, tectonic structure, morphology of ore bodies, material structure and the natural types of ore, ore zoning. Besides this, main ore controlling factors are determined, the genetic classification of ore is offered, the milestones and stages of its formation are presented, the type of ore formation and its clones are established, the forecasting and search yardsticks are formulated.
