Tectonic Regimes of the Central and Southern Andes: Responses to Variations in Plate Coupling During Subduction
Journal ArticleDOI
Growth stratal records of instantaneous and progressive limb rotation in the Precordillera thrust belt and Bermejo basin, Argentina
TL;DR: In this article, a growth triangle that documents instantaneous forelimb rotation for a fault-propagation fold is recorded for the first time in a published seismic line, and the complex geometry of growth strata deposited on the back limb of the Las Salinas anticline can be explained by using a model of a two-step fault propagation fold with constant layer thickness.

Thick-skinned and thin-skinned thrusting in the La Ramada fold and thrust belt: crustal evolution of the High Andes of San Juan, Argentina (32°SL)
TL;DR: In this article, a two-layer model with a middle detachment level is proposed to explain the spatial decoupling between maximum shortening at the surface and maximum crustal thickening.
Journal ArticleDOI
Unsteady and spatially variable evolution of the Neogene Andean Bermejo foreland basin, Argentina
TL;DR: The Miocene to Recent Bermejo retroarc foreland basin formed during development of the Andes Mountains and Sierras Pampeanas broken foreland, in west-central Argentina as discussed by the authors.
Journal ArticleDOI
Thrust-front zone of the Precordillera, Argentina; a thick-skinned triangle zone
TL;DR: In this paper, the authors divide the frontal thrust zone of the Precordillera thrust belt of western Argentina into three segments based on the system's activity: independent, late interfering, and collision zones.

Balanced cross sections
TL;DR: In this paper, post-depositional concentric deformation produces no significant change in rock volume, and the surface area of a bed and its length in a bed remains constant.

Andean tectonics related to geometry of subducted Nazca plate
Teresa E. Jordan,Bryan L. Isacks,Richard W. Allmendinger,J. A. Brewer,J. A. Brewer,Victor A. Ramos,Clifford J. Ando,Clifford J. Ando +7 more
TL;DR: In this paper, the authors show that tectonic segmentation of the Andes coincides with the subducted Nazca plate, which has nearly horizontal segments and 30° east-dipping segments.

Paleozoic terranes of the central Argentine-Chilean Andes
Victor A. Ramos,Teresa E. Jordan,Richard W. Allmendinger,Constantino Mpodozis,Suzanne Mahlburg Kay,J. M. Cortes,M. Palma +6 more
TL;DR: In this paper, the authors present stratigraphic and petrologic data from Chile and Argentina between 29° and 33°S latitude that demonstrate the "suspect" nature of several major terranes, which they infer to have been accreted during the Paleozoic.
