The Loncopué Trough: A Cenozoic basin produced by extension in the southern Central Andes

Structure and development of the Andean system between 36° and 39°S

“…These are new data particularly for the main Andes and western Agrio and Chos Malal fold and thrust belts, but also from a compilation of previous works ( Figure 5) (Radic et al, 2002;Melnick et al, 2006a;Zamora Valcarce et al, 2006;Folguera et al, 2006Folguera et al, , 2007Folguera et al, , 2010Rojas Vera et al, 2010). M a n u s c r i p t These sections were made for most of the basement and simple detachment structures using 2D Move software, and restored using the flexural slip algorithm Egan et al, 1997).…”

“…Contrastingly, a late Oligocene to early Miocene extensional stage seems to be broadly developed through the sector analyzed here from the Chilean coast to the foreland zone ( Figure 15). This has been determined based on field and seismic data (Jordan et al, 2001;Rojas Vera et al, 2010;Folguera et al, 2010) as well as the chemical characteristics of related volcanic rocks (Ramos and Barbieri, 1989;Muñoz et al, 2000;Kay et al, 2006;Spagnuolo et al, 2010). The late Miocene contractional stage affects the fold and thrust belt differentially ( Figure 15A).…”

Repeated eastward shifts of arc magmatism in the Southern Andes: A revision to the long-term pattern of Andean uplift and magmatism

“…Similarly to the north synextensional emplacement was proposed for the Payenia-like products next to the Andean foothills (Rojas Folguera et al, 2010). (González Díaz, 1982;Ré et al, 2000;Espinoza et al, 2007).…”

Exhumation of the Neuquén Basin in the southern Central Andes (Malargüe fold and thrust belt) from field data and low-temperature thermochronology

“…The late Miocene -Present evolution of the region between 34° and 38°S is welldocumented (see Kay et al, 2006;Muñoz et al, 2000;Cobbold et al, 2008;Ramos and Folguera, 2009;Folguera et al, 2010). However, little attention has been paid to its earlier Paleogene evolution.…”
