Kasyanenko K. Petrology of the charnokitoyides from Litinska structure

The thesis is devoted to study of charnokite rocks from Litinskiy structure of Pobuzhya of the Ukrainian shield. According to the research among the charnokitoyids distinguished: two pyroxene enderbites, hypersthene enderbites and charnockites, among which there are numerous inclusions of xenoliths of metamorphic rocks including dnіstrovo-bugska series. Also in the study area hypersthene-garnet granites (vinnytsyty), which framing Litinskiy structure were allocated. Сharnokitoyides from Lityn career are magnesium types usually metaaluminum were established. They are characterized by the oxidized trends of differentiation. Charnokitoyides of Malinovsky career are ferruginous types. These rocks are close to the relatively anhydrous regenerative magma of the substrate. in the process of growth Litinskiy domed structure the composition of charnokitoyides changing of a basal in the peripheral part of a more acidic - in the center of the dome was shown. The existence of charnokitoyides mezoarhey age in the Litinskiy structure due to obtained isotope uranium-lead method age zircons (2.9 billion years) from charnokitoyides of Malinovsky career was confirmed. Litinskiy structure is a projection of the foundation paleoarhey old age among the younger rocks of Berdichevsky complex converted superimposed processes of mezoeoarhey was proved.
