South American reference pole for the mid-Cretaceous: further constraints in the interpretation of Andean paleomagnetic data

A paleomagnetic study of the Aptian Cerro Barcino Formation in central Patagonia showed the presence of a stable magnetization with a positive tilt test. The obtained pole position (lat 85°S, long 181°E, α95 = 5.6°, N = 11) differs from reliable Early and Late Cretaceous South American cratonic pole...
