Resumen
This Special Issue gathers a series of contributions derived frompresentations at the 19 Congreso Geologico Argentino held inCordoba in 2e6 June 2014. Specific subjects cover a wide varietyof topics and regions of the Argentine and Chilean Andes, varyingfrom sedimentological analyses and U/Pb dating of detrital zirconsin different rocks to determine source areas for different times andregions along the southern Andes; satellite gravity data for monitoringearthquakes at the subduction zone to understand theircomplex rupture structure; fission track data from the Andes tothe foreland region; use of seismic tomographies and conventionalseismic reflection data for analyzing crustal structure; to paleomagneticdata and structural and morphological analyses.From north to south, the work of Arriagada et al. located in theforearc analyzes the pattern of rotations of northern Chile usingpaleomagnetic data. They note anomalous rotations in Permian toCretaceous rocks that are not consistent with magnitude of rotationsassociated with the oroclinal bending of the Central SouthAmerican margin.
