Lithium concentrations and isotope signatures of Palaeozoic basement rocks and Cenozoic volcanic rocks from the Central Andean arc and back-arc
(Springer, 2019-08)
We investigate the Li isotope composition and the Li concentrations of metamorphic and sedimentary rocks of the Palaeozoic (Pz) basement in the Central Andes and follow the trace of the Li in the Cenozoic volcanic rocks ...
The Early Palaeozoic high-grade metamorphism at the active continental margin of West Gondwana in the Andes (NW Argentina/N Chile)
(Springer Verlag Berlín, 2011-04)
The evolution of the Early Palaeozoic orogen of West Gondwana in the Cambrian to Ordovician basement of the Andes between *18 and 32 S is investigated for pressure and temperature conditions and age of metamorphism. It is ...
Provenance of Austroalpine basement metasediments: tightening up Early Palaeozoic connections between peri-Gondwanan domains of central Europe and Northern Africa
(Springer, 2018-09)
New U–Pb and Lu–Hf detrital zircon data together with whole-rock geochemical and Sm–Nd data were obtained for paragneisses of the Austroalpine basement south of the Tauern Window. Geochemically immature metasediments of ...
Evolution of the Palaeozoic basement of the North Patagonian Andes in the San Martín de los Andes area (Neuquén, Argentina): petrology, age and correlationsEvolución del basamento paleozoico de los Andes Norpatagónicos en el área de San Martín de los Andes (Neuquén, Argentina): petrología, edad y correlaciones
(Servicio Nacional de Geología y Minería, 2019-01)
En el entorno de San Martín de los Andes (Patagonia argentina), el basamento Paleozoico está constituido por rocas metamórficas e ígneas. Las rocas metamórficas de esta área incluyen esquistos, gneises y migmatitas ...
Neoproterozoic to lower Palaeozoic successions of the Tandilia System in Argentina: Implication for the palaeotectonic framework of southwest Gondwana
(Springer, 2011-04)
The Cryogenian to Uppermost Ediacaran successions of the Tandilia System (Sierras Bayas Group and Cerro Negro Formation) in central-eastern Argentina is exceptional because of its unmetamorphosed and nearly undeformed ...
The Mojotoro Range, eastern cordillera, Salta province
(Universidad Nacional de Tucumán. Facultad de Ciencias Naturales e Instituto Miguel Lillo. Instituto Superior de Correlación Geológica, 2003)
The Mojotoro Range (MR) is located at the SE end of the Argentine Eastern Cordillera, to the east of Salta City (Figure 7a,b). From a structural point of view, the MR is a complex anticlinorioum of N–S strike that closes ...
Evolution of the Palaeozoic basement of the North Patagonian Andes in the San Martín de los Andes area (Neuquén, Argentina): petrology, age and correlations
(Servicio Nacional de Geología y Minería, 2019)
Geodynamic implications of ophiolitic chromitites in the La Cabana ultramafic bodies, Central Chile
(2014)
Chromitites (>80% volume chromite) hosted in two ultramafic bodies (Lavanderos and Centinela Bajo) from the Palaeozoic metamorphic basement of the Chilean Coastal Cordillera were studied in terms of their chromite composition, ...
Reactivation, inversion and basement faulting and thrusting in the Sierras Pampeanas of Córdoba (Argentina) during Andean flat-slab deformation
(Cambridge University Press, 2016-06)
The Sierras Pampeanas of Córdoba are the easternmost uplifted blocks caused by Andean foreland deformation, over 700 km from the Chile trench. This deformation started at c. 340 Ma through basement faults, thrusts and ...
