Stages in evolution of Earth's crust recorded by the Huliaipole block of the West Azov area (4.0-2.0 Ga)
The U-Pb age of zircon populations from metadacite of the Huliaipole Suite was determined using the LA-ICP-MS method as 3085-2850 and 3700-3360 Ma. In addition, two crystals of zircon were discovered with an age of more than 3800 Ma. According to geological and geochronological data, the Huliaipol...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The U-Pb age of zircon populations from metadacite of the Huliaipole Suite was determined using the LA-ICP-MS
method as 3085-2850 and 3700-3360 Ma. In addition, two crystals of zircon were discovered with an age of more
than 3800 Ma. According to geological and geochronological data, the Huliaipole Block, 30 × 50 km in size, is composed
of rocks and relicts of the Hadean, Archean, and Palaeoproterozoic eons. The oldest nucleus of the Azov Domain
was probably formed from 3.97 to 3.3 Ga ago. In the Mesoarchean (3.2-3.0 Ga), it became a part of the Middle
Dnieper-Azov-Kursk granite-greenstone terrane. Felsic and intermediate volcanics of the Huliaipole Suite could
have formed due to the melting of the sialic crust, including rocks of the Hadean and Archean age, as a result of the
underplating of basic melts during the formation of the Neoarchean to Paleoproterozoic rift structures. |
