Abstract The proto-Andean and Early Andean evolution of the southwestern Gondwana
margin comprises three stages that differ in their magmatic evolution and deformational …

The temporal transition from backarc extension to retroarc shortening is a fundamental
process in the evolution of many Andean-type convergent margins. This switch in tectonic …

In this classic segment, many tectonic processes, like flat-subduction, terrane accretion and
steepening of the subduction, among others, provide a robust framework for their …

We explore the temporal evolution of pre-Andean Cordilleran arcs in central and
northwestern Argentina and northern Chile (27°–34° S) with a focus on the geochemical …

The spatial and temporal distribution of arc magmatism and associated isotopic variations
provide insights into the Phanerozoic history of the western margin of South America during …

Magmatic activity in continental arcs is known to vary in a non-steady-state manner, with the
mechanisms driving magmatic activity being a matter of ongoing discussion. Of particular …

Abstract The Upper Jurassic volcanic rocks of the Pre-Cordillera and High Andes of northern
Chile (26–31° S) represent a back-arc magmatic chain formed during an earlier stage of …

Status and correlation of Andean ammonite biozones are reviewed. Available calpionellid,
nannofossil, and radiolarian data, as well as radioisotopic ages, are also considered …

New U–Pb detrital zircon ages are presented for the Tordillo Formation. The ages indicate
that the most important source region of sediment supply was the Jurassic Andean arc …

We assess the role of inherited structures on the Meso‐Cenozoic tectonic evolution of the
main Andean Cordillera in central Chile (33° 30′ S‐34° S). Based on extensive field …
