英文摘要	The pre-Alpine basement of the Apuseni Mountains (Romanian Carpathians) comprises three terranes: Somes, Baia de Aries and Biharia. Metaigneous rocks within these terranes record Late Cambrian-Ordovician U-Pb zircon crystallization ages. Two samples from an orthogneiss layer in the Somes, terrane yielded an age of 459.8 +/- 2.7 Ma. In the Baia de Aries, terrane, an augen gneiss yielded an age of 470.8 +/- 3.8 Ma, a porphyroid yielded an age of 467.8 +/- 3.8 Ma and two metagranites yielded ages of 467.8 +/- 4.7 Ma and 467.1 +/- 3.9 Ma, respectively. Three samples from a metagranitoid outcrop located in the lower part of the Biharia terrane yielded an age of 495.0 +/- 2.1 Ma. Three other samples from a metabasite layer situated lithostratigraphically several hundred metres above the metagranitoid yielded an age of 477.8 +/- 3.2 Ma. Detrital U/Pb zircon ages from a paragneiss interlayered within the Baia de Aries, terrane scatter between 548 and 3518 Ma. Detrital zircon ages together with the inherited ages recorded by magmatic zircon populations suggest a northeastern Gondwanan provenance for the Somes,, Baia de Aries, and Biharia terranes, adjacent to the Arabian-Nubian Shield. Lead loss in some zircons is interpreted to have taken place during the Variscan orogeny.
