Miocene to Quaternary deformation of the Guañacos fold-and-thrust belt in the Neuquén Andes between 37°S and 37°30′S
(Geological Society of America, 2006)
The fold and thrust belt of the Neuquén Andes between 37° and 37°30´S can be divided into two sectors that show contrasting evolutionary styles.The outer or eastern section contains the relatively well known Agrio and Chos ...
Tectonic evolution of the northern Malargüe Fold and Thrust Belt, Mendoza province, Argentina
(Pergamon-Elsevier Science Ltd, 2020-11)
In this work we study the evolution of one particular segment of the Southern Central Andes, the northern sector of the Malargüe Fold and Thrust Belt (34°–35° LS), where limited access to the western section has delayed ...
Structural style of the Malargüe fold-and-thrust belt at the Diamante River area (34°30'-34°50'S) and its linkage with the Cordillera Frontal, Andes of central Argentina
(Pergamon-Elsevier Science Ltd, 2010-04)
The Malargüe fold-and-thrust belt is a thick-skinned belt developed in Miocene-Pliocene times during the Andean orogeny, which together with the Cordillera Frontal constitutes the Andes of central Argentina in the Diamante ...
Thrust-fold belt kinematics and orogenic growth in Tierra del Fuego, Argentina: implications of backthrusting for critical Coulomb wedge development
(Universidad de Oviedo, 2010-02)
Analysis of balanced cross-sections and of the chronostratigraphy of the deformed foreland basin successions allows to solve the structural kinematics of the eastern Fuegian thrust-fold belt. Based on the Coulomb wedge ...
Kinematic models of basement/cover interaction: Insights from the Malargüe fold and thrust belt, Mendoza, Argentina
(Pergamon-Elsevier Science Ltd, 2009-12)
We investigate through natural examples from the Malargüe fold and thrust belt the manner in which the basement structures interact with the cover in a thick-skinned fold and thrust belt. Our work suggests that there is a ...
Oblique half-graben inversion of the Mesozoic Neuquén Rift in the Malargüe Fold and Thrust Belt, Mendoza, Argentina: New insights from analogue models
(Pergamon-Elsevier Science Ltd, 2008-07)
The Malargüe fold and thrust belt, located in the Andean mountains between 34°S and 36°30′S, formed in response to contraction during Cenozoic times. Its structural style and geometry was controlled by the Mesozoic rift ...
Superposed deformation in the Península Mitre recess (Fuegian thrust-fold belt, Southern Argentina), and implications for orogenic curve kinematics
(Pergamon-Elsevier Science Ltd, 2019-12)
A detailed study of the structure of the Península Mitre recess in the Fuegian thrust-fold belt of southern Argentina reveals superposed deformation related to contrasting shortening directions. One group of structures ...
Progressive deformation of a Coulomb thrust wedge: The eastern Fuegian Andes Thrust-Fold Belt
(Geological Society Publications House, 2011-01)
Time-calibrated balanced-cross sections of the eastern Fuegian Thrust-Fold Belt reveal many complex pro- and retro-vergent structures, rooted at the base of Cretaceous and within Paleocene rocks. These structures involve ...
Influence of the orientation of cohesive blocks upon the structural grain of fold-and-thrust belts: An appraisal by means of analogue modeling
(Elsevier, 2020)
Analogue sand-box experiments have been set up to illustrate and analyze the control exerted by lithological heterogeneities on the evolution of a model fold-and-thrust belt (FTB). The structural architecture within many ...
