A few single crystal zircon ages from the Padeş suite orthogneisses (Southern Carpathians, Romania)

Abstract

The Padeş suite from the Poiana Ruscă Mountains is a component of the Padeş Paleozoic terrane. The Padeş terrane evolved as an island arc between the Cadomian Sebeş-Lotru and Făgăraş terranes, the main parts of the Getic crystalline in the Southern Carpathians. Evaporated single zircon grains offered 394±20 Ma, 546±20 Ma, 655±19 Ma, 1305±17 Ma, and 1538±17 Ma ages. The 394 Ma age has been interpreted as an early Variscan collision age, 546 Ma as the protolith age and the other ages as signifying Cadomian and Saharan detrital zircons. Similar to the terranes in the Apuseni Mountains, the Padeş terrane has a North African-Gondwanan provenance.
