Geological Records of the Fuegian Andes Deformed Complex Outlined in a Patagonian Orogenic Belt Regional Context
(Springer, 2019)
The Fuegian Andes show simple and complex aspects in the Argentine portion. The simple aspects refer to the general stratigraphy and the complex ones result from tectonic characteristics. In a stratigraphic point of view ...
Eastern Sector of the Fuegian Andes Deformed Complex (FADC-ES)
(Springer, 2019)
The FADC-ES comprises the territories located east of an imaginary line projected from Bahía Aguirre to Policarpo Cove, known as Península Mitre . The Montes Negros and Atocha, Campana and Pirámide hills are situated there, ...
Western Sector of the Fuegian Andes Deformed Complex (FADC-WS)
(Springer, 2019)
The Mesozoic complex starts here from the simplest chrono-stratigraphic chart, consisting of a thick marine layer of Late Jurassic-Early Cretaceous age, superimposed to Jurassic volcanic and sedimentary rocks and overlain ...
The Deformed Complex and the Formational Units
(Springer, 2019)
The formational units that appear in the available geological fuegian literature, and that are found within the Deformed Complex of the Fuegian Andes, are the Metamorfita Lapataia (i.e., Lapataia Metamorphites), and the ...
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 ...
Structure and evolution of the Fuegian Andes foreland thrust-fold belt, Tierra del Fuego, Argentina: Paleogeographic implications
(Pergamon-Elsevier Science Ltd, 2008-06)
Field work in the frontal part of the foreland thrust-fold belt of the Fuegian Andes reveals complex relationships between stratigraphy and structure. Construction of balanced cross-sections allows us to infer the geometry ...
Mesozoic-Cenozoic stratigraphy of the Fuegian Andes, Argentina
(Universidad de Barcelona, 2008-03-26)
The stratigraphy of the Argentinean Fuegian Andes reveals contrasting Mesozoic-Cenozoic tectonic regimes. The Lemaire Formation, submarine complex of bimodal volcanites, breccias, and sedimentary rocks; the Yahgán Formation, ...
A Simplified View about the Fuegian Andes and the Complex Folding of the Mesozoic and Early Tertiary Layers
(Springer, 2019)
The arch described by the Patagonian orogenic belt in Tierra del Fuego and the acute folding of the Mesozoic and earliest Tertiary strata are not two independent phenomena. The search for the causes that have produced these ...
Structural geology of the Fuegian Andes and Magallanes fold and thrust belt: Tierra del Fuego Island
(Universidad de Barcelona, 2008-12)
A synthesis of the structural geology of the Tierra del Fuego Island, which integrates a new data set derived from field surveys and literature data of the last few years, is here presented. The main geological features ...
The Basic Eruptive Rocks of Alvear and Sorondo Ranges
(Springer, 2019)
One matter of interest is the one concerning the basalts-andesites and diabase-microgabbros of the Alvear and Sorondo ranges. They have been described as vein-layer interbedding in the sedimentary frame of the Yahgan Fm. ...
