The Danubian domain basement of the South Carpathians, Romania, comprises two Neoproterozoic continental crustal fragments, the Drǎgşan and Lainici-Pǎiuş terranes, which were sutured by the closure of an intervening oceanic domain, the Tişoviţa terrane. Magmatic and detrital zircons extracted from an orthogneiss, four granitoid plutons, two metasedimentary units, and a Liassic sandstone were dated by zircon U/Pb LA-ICP-MS. The Fǎgeţel augen gneiss from the Drǎgşan terrane basement yielded an age of 803.2 ± 4.4. Ma, the oldest well-constrained crystallization age reported from the Romanian Carpathians basement. The Tismana, Şuşiţa, Novaci and Olteţ granitoid plutons, which intrude the Lainici-Pǎiuş terrane basement, yielded ages of 600.5 ± 4.4, 591.0 ± 3.5, 592.7 ± 4.9, and 588 ± 2.9. Ma, respectively. The Tismana granitoid age of 600. Ma and the youngest detrital zircon ages of 637-622. Ma from a metaquartzite within the Lainici-Paiuş terrane, constrain the deposition of the metaquartzite protolith to ca. 620-600. Ma. The 803. Ma age represents an old Pan-African age, whereas the younger Neoproterozoic ages suggest Pan-African/Cadomian thermotectonic events. Detrital and inherited zircon ages within the Drǎgşan and Lainici-Paiuş terranes attest to a peri-Amazonian, Avalonian-type provenance for the Drǎgşan terrane and possibly a Ganderian-type provenance for the Lainici-Pǎiuş terrane. The Lainici-Pǎiuş terrane rifted off Gondwana before the Drǎgşan terrane. Both terranes were attached to Moesia during the Early Paleozoic.
