Age and provenance of the Beardmore Group, Antarctica: Constraints on Rodinia supercontinent breakup

Goodge, John W; Myrow, Paul M; Williams, Ian; Bowring, Samuel A


New U-Pb ages for detrital and igneous zircons constrain the depositional age and sedimentary provenance of the Beardmore Group, a siliciclastic succession that records transformation of the East Antarctic margin during Rodinia breakup and subsequent Gondwana amalgamation. We divide rocks previously mapped as the Beardmore Group into (1) an inboard late Neoproterozoic assemblage (probably ≤670 Ma) and (2) a volumetrically dominant, outboard assemblage that is latest Early Cambrian or younger...[Show more]
