Crustal structure of the high Andes in the North Pampean flat slab segment from magnetic and gravity data
(Pergamon-Elsevier Science Ltd, 2017-01)
The Main Andes at the northern Chilean-Pampean flat slab segment were formed by the inversion of late Oligocene to early Miocene extensional depocenters in Neogene times. Their structure, size and depth are loosely constrained ...
The Proterozoic basement of the Arequipa massif, southern Peru: Lithologic domains and tectonics
(IRD ÉditionsFRA, 2008)
The Proterozoic rocks outcrops along the southern coast of Peru, on the margin of the Pacific Ocean and extends in the Western Cordillera of the Andes, forming a major exhibition of pre-Andean rocks where tectonothermal ...
Proterozoic-Paleozoic development of the basement of the Central Andes (18-26°S) - A mobile belt of the South American craton
(Pergamon-Elsevier Science Ltd, 2000-12)
The Late Precambrian-Early Paleozoic metamorphic basement forms a volumetrically important part of the Andean crust. We investigated its evolution in order to subdivide the area between 18 and 26°S into crustal domains by ...
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 ...
The pre-Mesozoic rocks of northern Chile: U-Pb ages, and Hf and O isotopes
(Elsevier, 2016)
Supposed pre-Mesozoic igneous and metamorphic rocks from northern Chile are reviewed in the light of twenty-one new SHRIMP U-Pb zircon age determinations. Metamorphic rocks from the precordillera upthrust belt mostly show ...
