Laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) U-Pb ages of more than 400 detrital zircons from the Neoproterozoic–early Paleozoic clastic sequences of Carolinia range from ca. 530 Ma (Early Cambrian) to ca. 2600 (Archean). The majority of analyzed zircon grains are late Neoproterozoic (Ediacaran), with minor amounts of Mesoproterozoic–Paleozoic and accessory Archean grains. The overall distribution of age populations of detrital zircons is consistent with sediment derivation from the Amazonian craton and its peripheral orogenic belts on the margin of west Gondwana. On the basis of the age of the youngest detrital zircon populations (ca. 550 Ma), the Uwharrie, Tillery, Cid,...
