Magmatic Evolution of the Southernmost Andes and its Relation with Subduction Processes
(Springer, 2015)
The magmatic arc in the SouthernmostAndes is represented by the Fuegian Batholith and satellite plutons, plus minorvolcanic and volca-niclastic sequences. Magmatism was active from the LateJurassic to the Miocene in response ...
The geodynamic history of the Famatinian arc, Argentina: A record of exposed geology over the type section (latitudes 27°- 33° south)
(Pergamon-Elsevier Science Ltd, 2020-06-14)
The Famatinian arc, over central-western Argentina, is one of the few examples of exposed crustal arc cross-section in the world. This Paleozoic magmatic arc and orogenic system on the Earth's surface offers unique insights ...
The Sierra de Macon, Plutonic expression of the Ordovician magmatic arc, Salta Province Argentina
(Pergamon-Elsevier Science Ltd, 2004-12)
The Macon granitoids are part of a tonalite/diorite granodiorite suit. Their trace elements place these rocks in the volcanic arc field. They have distribution patterns similar to those observed for rocks from Choschas, ...
Constraints on Trenchward Arc Migration and Backarc Magmatism in the North Patagonian Andes in the Context of Nazca Plate Rollback
Geochemical and geochronological data reveal that late Oligocene-early Miocene time is a break point in the evolution of Andean magmatism. The Patagonian Andes registered the onset of arc volcanism since the late Eocene ...
O-H-Sr-Nd isotope constraints on the origin of the Famatinian magmatic arc, NW Argentina
(Cambridge University Press, 2020-12)
We report a study of whole-rock O-H-Sr-Nd isotopes of Ordovician igneous and metamorphic rocks exposed at different crustal palaeodepths along c. 750 km in the Sierras Pampeanas, NW Argentina. The isotope compositions ...
Pacific subduction coeval with the Karoo mantle plume: the Early Jurasssic Subcordilleran belt of northwestern Patagonia
