New constraints from U-Pb, Lu-Hf and Sm-Nd isotopic data on the timing of sedimentation and felsic magmatism in the Larsemann Hills, Prydz Bay, East Antarctica

Complexly deformed gneisses in the Larsemann Hills, southern Prydz Bay, are customarily divided into a basement igneous complex (Søstrene Orthogneiss) and overlying metasediments (Brattstrand Paragneiss). New ion microprobe U-Pb zircon ages support this
