Pan-African intraplate deformation in the northern Prince Charles Mountains, east Antarctica

Boger, Steven D.; Carson, Christopher J; Fanning, Christopher; Hergt, Janet; Wilson, Colin J; Woodhead, Jonathan


New structural and metamorphic data coupled with U-Pb SHRIMP zircon and Rb-Sr step-leach biotite ages help constrain a period of Early Palaeozoic (Pan-African) deformation recognised in the northern Prince Charles Mountains, east Antarctica. This period of deformation is accommodated along discrete northeast trending mylonites that preserve up-dip reverse kinematics with dominantly southeast over northwest vergence. Ambient P-T conditions of 524 ± 20°C and 7.6 ± 4 kbar accompanied deformation....[Show more]
