Paleomagnetic evidence of an early Paleozoic rotated terrane in northwest Argentina: A clue for Condwana-Laurentia interaction?

Paleomagnetic results from three Lower Ordovician units in northwest Argentina are reported. When assessed with available geologic evidence, these data permit the definition of the Puna Oriental-Famatina rotated terrane. Paleogeographic reconstructions based on these paleomagnetic results place Puna...
