TL;DR: In this article, the authors studied the orogenic effects of flat subduction in an active convergent margin in the Pampean segment of Argentina and Chile (27°00′ −33°30′S) and found that the main deformation phases and uplift of the thin and thick-skinned fold and thrust belts of the principal and frontal Cordilleras of the Sierras Pampeanas occurred between 20 and 8.6 Ma.

TL;DR: In this article, global positioning system data from southern Central America and northwestern South America were collected during 1991, 1994, 1996, and 1998 in Costa Rica, Panama, Ecuador, Colombia, and Venezuela.

TL;DR: Recently published seafloor data around the Antarctica plate boundaries, as well as calibration of the Cenozoic Magnetic Polarity Time Scale, allow a reevaluation of the Nazca (Farallon) and South America relative convergence kinematics since late Middle Eocene time as discussed by the authors.

TL;DR: In this paper, changes in the Neogene (Miocene to recent) magmatic style of the modern Chilean flat-slab region and its margins (27-34°S) reflect both variations in Nazca-South American convergence parameters and the effects of subduction of the Juan Fernandez Ridge hotspot track.

TL;DR: The Borborema Province of NE Brazil comprises the central part of a wide Pan-African-Brasiliano orogenetic belt that formed as a consequence of late Neoproterozoic convergence and collision of the Sao Luis-West Africa craton and the Sao Francisco-Congo-Kasai cratons as mentioned in this paper.
