Siliciclastic rocks in the Transantarctic Mountains record the tectonic transformation from a Neoproterozoic rift-margin setting to a passive-margin and ultimately to an active early Paleozoic orogenic setting along the paleo-Pacific margin of East Antarctica. New U-Pb detrital-zircon ages constrain...
