The Amalgamation of Pangaea and the Sonoma Orogeny: Early Permian to Early Triassic – Ca. 300–240 Ma

Abstract

With the amalgamation and assembly of Pangaea in the late Paleozoic, a hypothetical visitor could have traveled entirely by land from the western edge of the supercontinent in Nevada, across Laurentia and the Appalachian crest, to the plains of Eastern Europe, across the Ural Mountains in Russia, and then southward through Africa, India, Australia, and Antarctica (Fig. 6.1). The equator now trended from just south of Arizona through Texas, North Carolina, on to Algeria and out to the Paleo-Tethys Sea, a part of the Panthalassa Ocean.
