Upper Plate Controls on the Formation of Broken Foreland Basins in the Andean Retroarc Between 26°S and 28°S: From Cretaceous Rifting to Paleogene and Miocene Broken Foreland Basins
(American Geophysical Union, 2020-06)
Marked along-strike changes in stratigraphy, mountain belt morphology, basement exhumation, and deformation styles characterize the Andean retroarc; these changes have previously been related to spatiotemporal variations ...
Along-strike segmentation of the Farallon-Phoenix midocean ridge: Insights from the Paleogene tectonic evolution of the Patagonian Andes between 45° and 46°30′S
(Elsevier, 2019)
The kinematics of the Farallon-Phoenix-South America triple junction during the Cretaceous and Paleogene periods remain incompletely resolved. Geological studies have interpreted Paleocene-Eocene ridge subduction beneath ...
Dated phylogenetic studies of the southernmost American buthids (Scorpiones; Buthidae)
(Academic Press Inc Elsevier Science, 2017-05)
A dated molecular phylogeny of the southernmost American species of the family Buthidae, based on two nuclear and two mitochondrial genes, is presented. Based on this study, analyzed species of the subgenus Tityus ...
Crustal structure of the high Andes in the North Pampean flat slab segment from magnetic and gravity data
(Pergamon-Elsevier Science Ltd, 2017-01)
The Main Andes at the northern Chilean-Pampean flat slab segment were formed by the inversion of late Oligocene to early Miocene extensional depocenters in Neogene times. Their structure, size and depth are loosely constrained ...
Multiple approaches to understanding the taxonomic status of an enigmatic new scorpion species of the genus Tityus (Buthidae) from the biogeographic island of Paraje Tres Cerros (Argentina)
(Public Library of Science, 2017-07-26)
Tityus curupi n. sp., belonging to the bolivianus complex, is described from the biogeogra-
phically distinct area of Paraje Tres Cerros in north-eastern Argentina. We also present a
molecular species delimitation ...
Extensional tectonics during Late Cretaceous evolution of the Southern Central Andes: Evidence from the Chilean main range at ~35°S
(Elsevier B.V., 2018)
The study of Late Cretaceous-earliest Paleogene series in the Chilean Andes at ~35°S provides new constraints on
the coeval evolution of the area and the Southern Central Andes. These correspond to the continental series ...
Transient plate contraction between two simultaneous slab windows: Insights from Paleogene tectonics of the Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2018-11)
Plate kinematic reconstructions show that the Farallon-Phoenix (Aluk) spreading center subducted under South America sometime between the Late Cretaceous and the Paleogene periods. Geological studies have supported a ...
Evolution of paleogene basins in northwestern southamerica: tracking the change from caribbean to nazca subduction
(Departamento de Geociencias, 2012)
In the northern Andes, inversion of mesozoic extensional structures, have controlled the location of synorogenic successions and dispersal of detritus since Paleocene time. Detailed geologic mapping, tectosedimentological ...
