The low‑grade basement at Península La Carmela, Chilean Patagonia: new data for unraveling the pre‑Permian basin nature of the Eastern Andean Metamorphic Complex
(2021)
The Eastern Andean Metamorphic Complex at Península La Carmela (48°50’S) consists of quartz-rich metaturbiditic sequences with tectonic slices of pillow metabasalt bodies deformed under low-grade metamorphic conditions. ...

Petrology and tectonic evolution of late Paleozoic mafic-ultramafic sequences and the Leones Pluton of the Eastern Andean Metamorphic Complex (46-47°S), southern Chile
(Pergamon-Elsevier Science Ltd, 2021-06)
The metamorphosed mafic-ultramafic sequences of the Eastern Andean Metamorphic Complex outcropping in the Patagonian Andes are critical to disclose the late Paleozoic tectonic evolution of the southwestern margin of Gondwana. ...
P-T conditions of metapelites from metamorphic complexes in Aysen, Chile
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-08)
Pressure and temperature metamorphic conditions were determined for K-white mica and chlorite in metapelites from the eastern Andean metamorphic complex (EAMC) and from the Chonos metamorphic complex (CMC) of southern ...
Detrital-zircon U-Pb geochronology of the Quebrada del Carrizo Metamorphic Complex and El Jardin Schists and spatially-related granitoids of the Sierra Castillo Batholith
(Servicio Nacional Geología Minerva, 2015)
U-Pb detrital-zircon geochronology of two discrete outcrops of mica schists of the western border of the Domeyko Cordillera in the Region of Atacama, northern Chile, indicates that the maximum age of sedimentation of their ...
The metamorphic rocks of the Nunatak Viedma in the Southern Patagonian Andes: Provenance sources and implications for the early Mesozoic Patagonia-Antarctic Peninsula connection
(Journal of South American Earth Sciences, 2019-03)
The Nunatak Viedma within the Southern Patagonian Icefield has been considered as a volcanic center based on its geomorphologic features, despite the fact that field explorations by Eric Shipton determined its metamorphic ...
MORB-derived amphibolites in the paleozoic basement of the aluminé igneous-metamorphic complex, Neuquén, Argentina: Decoding its genesis, P-T evolution and pre-andean regional correlations
(Universidad de Barcelona, 2019-11)
Amphibolites included in the metapelitic sequence and as xenoliths in intrusive magmatic rocks outcropping in the southern sector of the Aluminé Igneous-Metamorphic Complex (AIMC), Neuquén, Argentina, are studied in detail ...
