The Collision of Patagonia: Geological Facts and Speculative Interpretations

Abstract. The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new allochthonous


. The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new 28 allochthonous alternatives and

Patagonia: where does it come from?

Based on the recent finding of archeocyathids in molassic middle Cambrian to Early Ordovician age-sequences of northern Patagonia the relationships between this southern part of South America and

The Paleozoic Central Patagonian Igneous Metamorphic Belt : its geodynamic 2 and tectonic interpretation based on Paleogeographic reconstructions 3

In the southwestern margin of the North Patagonian Massif there is a NW25 SE belt of igneous and metamorphic rocks defining a limit between the North 26 Patagonian Massif and southern Patagonia

The Gondwana connections of northern Patagonia

A multidisciplinary study (U–Pb sensitive high-resolution ion microprobe geochronology, Hf and O isotopes in zircon, Sr and Nd isotopes in whole-rocks, as well as major and trace element

Review of the polyorogenic Palaeozoic basement of the Argentinean North Patagonian Andes: age, correlations, tectonostratigraphic interpretation and geodynamic evolution

ABSTRACT The presence of metamorphic rocks along the North Patagonian Andes is well known. All these metamorphic rocks are intruded by plutonic igneous rocks of Devonian, Carboniferous and Permian

The Continental Crust of Northeastern Patagonia

Abstract. The basement of northeastern Patagonia is characterized by Early Paleozoic igneous and metamorphic rocks that do not crop out in the central, western and Andean sectors of the North



Paleogeographic Development of South America

The post-Proterozoic geologic history of South America was controlled by the distribution and interplay of certain major geotectonic units, classed in five groups, which form the structural framework

Abstract It is now accepted that southern South America was formed from several terranes of diverse origin and evolution. However, a detailed history of the accretionary processes has not been

Provenance of late Palaeozoic metasediments of the Patagonian proto-Pacific margin (southernmost Chile and Argentina)

In this provenance study of late Palaeozoic metasediments of the Eastern Andean Metamorphic Complex (EAMC) along the south Patagonian proto-Pacific margin of Gondwana, the palaeogeological setting of

Tectonic accretion and the origin of the two major metamorphic and plutonic welts in the Canadian Cordillera

The Omineca Crystalline Belt and Coast Plutonic Complex are the two major regional tectonic welts in the Canadian Cordillera in which were concentrated intense deformation, regional metamorphism,

Thrust tectonics in the North Patagonian Massif (Argentina): Implications for a Patagonia plate

[1] In the northeastern segment of the North Patagonian Massif (southern Argentina), S to SW directed thrusting affected a Late Proterozoic to Cambrian phyllite succession and the Silurian to Lower

Terrane processes at the margins of Gondwana

The process of terrane accretion is vital to the understanding of the formation of continental crust. Accretionary orogens affect over half of the globe and have a distinctively different evolution
