Semenenko Institute of Geochemistry, mineralogy and Ore Formation popup.description2 Object of study - gneisses, amphibolites and basic krystaline shists of westpryazov and auly series Azov and Middle-Dnieper megabloks. Purpose - to determine the age division and geochemical characteristics and genesis of highmetamorphick rocks of westpriazov and auly series of eastern part of the Ukrainian shield. Methods - geological, structural, petrographic, mineralogical, geochemical, isotope-geochronological. As a result geochronological studies was first established the age and position kayinkulak and verhnetokmak thicknes of westpriazov series. Determined that plagiogneisses kayinkulak thicknes was mezoarhean - (3,1-3,0 Ga), and tonalite gneiss verhnetokmak thicknes - paleoarchean age (3.56 Ga). Determined that the majority of the area West-Priazov block composed heavily dislocated plagiogranitoids mezoarhean age (kayinkulak thicknes), as well as on Middle-Dnieper megablock (bazavluk thicknes) and conclude them essentially the same structure. Shown that plagiogneisses bazavluk thickness of auly series is uneven formations, among them gneiss under 3.18 and 2.95 Ga. Determined that the tectonic inclusion metabasite in rocks westpriazov series is intrusive (dike) rocks. Paleoarchean gneiss West Azov and Orihovo-Pavlogradsky structure represented breeds average composition (quartz diorite). These new geochronological data allow us to make the following changes to the time-stratigraphy scale: 1) plagiogneisses kayinkulk thickness of westpriazov series moved from paleoarhean to mezoarchean. They are coeval with plagiogranitoids TTG series (3,1-3,0 Ga). 2) tonalite gneiss verhnetokmak thickness put at 3.56 Ga; 3) on the Azov megablocki are two tonalite intrusive complex under 3.67 and 3.5 Ga; 4) allocate time-scale scheme Azov megablock plagiogranitoids TTG series under 3,1-2,92 billion years.
