A new limit for the NW Río de la Plata Craton Border at about 24ºS (Argentina) detected by Magnetotellurics

Old South American structures constitute a puzzle where the Río de la Plata craton is the most important clue in the assembly of SW Gondwana. The present study was performed to improve the knowledge resulting from all the previous magnetotelluric (MT) studies focused particularly on characterizing t...
