Paleomagnetism of the Carboniferous Tepuel Group, central Patagonia, Argentina

Samples of the Carboniferous glaciogenic sequences of the Tepuel Group, western central Patagonia, Argentina, were collected from 23 sites in two localities, Sierra de Tepuel. A characteristic remanent magnetization was determined in most sites by alternating field and/or thermal cleaning. The paleo...

Description
Summary:Samples of the Carboniferous glaciogenic sequences of the Tepuel Group, western central Patagonia, Argentina, were collected from 23 sites in two localities, Sierra de Tepuel. A characteristic remanent magnetization was determined in most sites by alternating field and/or thermal cleaning. The paleomagnetic pole for the Tepuel Group (Namurian-Westphalian) at 316.1°E, 31.7°S is considered a key pole for the Middle Carboniferous of South America and Gondwana, confirming the apparent polar wander path for the supercontinent for which the pole moved from central to southern Africa in the Early Carboniferous, followed by a rapid motion from southern Africa to Antarctica during the late Westphalian. -from Authors
