Paleomagnetism of the Lower Jurassic Lepa and Osta Arena formations, Argentine Patagonia

A paleomagnetic study in Upper Pliensbachian-Lower Toarcian rocks of Extra-Andinian Patagonia was carried out. Characteristic magnetizations isolated from three sections pass the tilt test. The resulting Early Jurassic paleomagnetic pole (PP) (Long. = 129.4°E, Lat. = 75.5°S, A95 = 6.8°, N = 13, K =...
