From Crustal Thickening to Orogen‐Parallel Escape: The 120‐Myr‐Long HT‐LP Evolution Recorded by Titanite in the Paleozoic Famatinian Backarc, NW Argentina
(American Geophysical Union, 2020-09)
Exposed sections of accretionary orogens allow reconstruction of their tectonic evolution. Most commonly, orogens are characterized by two‐dimensional shortening perpendicular to the orogenic front. We describe the midcrustal ...
Zircon inheritance from long-lived sources of Late Triassic post-orogenic plutons, High Andes, Central Chile (similar to 30 degrees S): Magmatic feedbacks and petrogenetic implications
(Elsevier, 2020)
A comprehensive understanding of the magmatic system evolution and petrogenetic environment is crucial for the correct interpretation of magmatic zircon age spectra. In the Central Andes, a protracted Late Paleozoic period ...
Distribution of active faulting along orogenic wedges: Minimum-work models and natural analogue
(Elsevier, 2014-09)
Numerical 2-D models based on the principle of minimum work were used to examine the space-time distribution of active faulting during the evolution of orogenic wedges. A series of models focused on thin-skinned thrusting ...
Geodynamic evolution of the Southern Brasília orogen (SE Brazil): new petrochronological insights from UHT and HP metamorphic rocks
(Universidade Federal de Minas GeraisUFMG, 2018-01-12)
The Southern Brasília orogen is one of the orogens formed around the São Francisco paleocontinent during the West Gondwana amalgamation. Its formation is interpreted to have been the result of the subduction of the passive ...
Zircon U-Pb ages and Hf isotopes for the Diablillos Intrusive Complex, Southern Puna, Argentina: Crustal evolution of the Lower Paleozoic Orogen, Southwestern Gondwana margin
(Pergamon-Elsevier Science Ltd, 2017-12)
The evolution of the rocks of the Lower Paleozoic Orogen in Puna, at the Southwestern Gondwana margin, has been widely debated. In particular, the scarce amount of geological and geochemical data available for the Diablillos ...
Lake formation, characteristics, and evolution in retroarc deposystems: A synthesis of the modern Andean orogen and its associated basins
(2015-01-01)
Lake deposystems are commonly associated with retroarc mountain belts in the geological record. These deposystems are poorly characterized in modern retroarcs, placing limits on our ability to interpret environmental signals ...
Migração de orógenos e superposição de orogêneses: um esboço da colagem brasiliana no Sul do Cráton do São Francisco, SE - Brasil
(Universidade de São Paulo, Instituto de Geociências, 2004)
Registros de eventos tafrogênicos intercalados tectonicamente no Complexo Pocrane, SE Minas Gerais
(Universidade Federal de Minas GeraisUFMG, 2017-05-25)
The internal domain of the Araçuaí-West Congo orogen comprises many varieties of rocks which were strong reworked during brasiliano orogenic cycle. In the vicinity of Pocrane and Durandé cities, western Minas Gerais, occurs ...
The Cariris Velhos tectonic event in Northeast Brazil
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The Borborema Province in northeastern South America is a typical Brasiliano-Pan-African branching system of Neoproterozoic orogens that forms part of the Western Gondwana assembly. The province is positioned between the ...
