The main precambrian tectonic structure features of the Ukrainian shield's Priazovsky granulite-greenstone area
Existing regards about a tectonic nature and structure of the Priazovsky granulite-greenstone area, the position and character of its Western border are considered. The area consists of four interconnected structural -formational zones: Orechovo-Pavlogradskaya and Central-Priazovskaja synclinoria zones, West-Priazovskaja and East-Priazovskaja anticlinoria zones. The assumption is made, that anticlinoria zones emerged in PaleoArchean time and in NeoArchean ("greenstone stage") and PaleoProterozoic time were inherited by arched uplifts.
