Crustal deformation of the Andean foreland at 31° 30′S (Argentina) constrained by magnetotelluric survey

Twenty-five new long-period magnetotelluric sites near 31.5°S were collected in a west–east profile. This profile and the previous one, aligned with and adjacent to the eastern end, have been merged to form a single profile of more than 700km long, extending from the Precordillera to the Chaco-Pampean Plain.
