FOCAL-CHANNEL MANIFESTATIONS OF PULSED INTRUSIVE AND PLUTON-DEGASSING PROCESSES AT DIFFERENT AGE STAGES OF THE FORMATION OF THE WESTERN AND CENTRAL PARTS OF THE UKRAINIAN SHIELD ACCORDING TO GEOPHYSICAL DATA
Abstract
and central part of the Ukrainian shield, the geological nature of which is attributed by the authors to channel-plutonic structures of different ages associated with the processes of magmatism and degassing of the Earth. According to drilling data and quantitative interpretation, such structures have the form of rods or inverted cones and are represented by intrusive rocks of ultramafic composition with iron and associated gold ore mineralization. A significant part of these structures is located in the zone of the Khmilnyk fault, which intersects the Podil and Bug Domains, as well as on its conditional extension within the boundaries of the Golovaniv suture zone. But on the territory of the shield, similar structures have a more initial distribution, which increases the search prospects for new types of minerals associated with the processes of intrusive magmatism and degassing of the Earth, and also provides new information about the history of the development of the shield.
