Evolution of Eocene to Oligocene arc-related volcanism in the North Patagonian Andes (39–41°S), prior to the break-up of the Farallon plate
Sofía B. Iannelli,Vanesa D. Litvak,Lucía Fernández Paz,Andrés Folguera,Miguel E. Ramos,Victor A. Ramos +5 more
TL;DR: In this paper, geochemical signatures indicate arc-related associations and reflect changing geodynamic boundary conditions of the Andean margin through time, and they propose that these compositional variations could be directly related to changes in plate configuration before and after the Farallon plate break-up and the initiation of a more orthogonal convergence typical of the present Andean-type subduction zone.

Geochemical and tectonic evolution of Late Cretaceous to early Paleocene magmatism along the Southern Central Andes (35-36°S)

TL;DR: In this paper, the authors focus on the petrological and geochemical characterization of a volcano-sedimentary sequence in the southern Andes of Mendoza province (35°30′S) and identify Late Mesozoic-Early Cenozoic magmatism.

Alternating contraction and extension in the Southern Central Andes (35°–37°S)

TL;DR: In this article, U-Pb dating of detrital zircons in a sample collected from the Los Angeles unit, a syn-extensional volcano-sedimentary succession located at ∼35°409S along the Chile and Argentina international border, provided a maximum depositional age of 67.1 +2.4/−0.9 Ma.

Late Eocene volcanism in North Patagonia (42°30′–43°S): Arc resumption after a stage of within-plate magmatism
Lucía Fernández Paz,Vanesa D. Litvak,Andrés Echaurren,Sofía B. Iannelli,Alfonso Encinas,Andrés Folguera,Victor A. Valencia +6 more
TL;DR: In this article, the authors focused on the El Maiten Belt, located in the present-day retroarc zone, particularly on a poorly studied section corresponding to the southern outcrops of this volcanic belt.

The role of the slab pull force in the late Oligocene to early Miocene extension in the Southern Central Andes (27°-46°S): Insights from numerical modeling
TL;DR: In this article, the authors reproduce a brief period of intra-arc basin formation that affected the Southern Central Andes (27°-46°S) during late Oligocene and early Miocene times.
