14 p, 1013.7 KB Mesozoic-Cenozoic stratigraphy of the Fuegian Andes, Argentina / Olivero, Eduardo Bernardo (CADIC-CONICET. Centro Austral de Investigaciones Científicas) ; Malumián, Norberto (SEGEMAR)
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, volcaniclastic apron of deep-marine andesite-rich turbidites and mudstones; and the Beauvoir Formation, slope mudstones, all evidence late Jurassic early Cretaceous extension and consequent origination of the Rocas Verdes Marginal Basin.

24 p, 7.4 MB Structural geology of the Fuegian Andes and Magallanes fold-and-thrust belt - Tierra del Fuego Island / Menichetti, Marco (Università di Urbino. Istituto di Scienze della Terra) ; Lodolo, Emanuele (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) ; Tassone, Alejandro (Universidad de Buenos Aires. Departamento de Geología) ; Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina) ; Universidad de Buenos Aires. INGEODAV (Instituto de Geofísica Daniel A. Valencio)
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 presented here. The main geological features of the region developed during the Mesozoic-Cenozoic Andean orogenic cycle that started in the Middle to Late Jurassic with a back-arc extension, crustal stretching and widespread volcanism, related to the break-up of Gondwanaland.

11 p, 1.1 MB The metamorphic complexes of the Patagonian and Fuegian Andes / Hervé Allamand, Francisco Enrique Isidoro (Universidad de Chile. Departamento de Geología) ; Calderón, Mauricio (Universidad de Chile. Departamento de Geología) ; Faúndez, Victor (Universidad de Chile. Departamento de Geología)
The Patagonian and Fuegian Andes are made up in part by late Paleozoic to Mesozoic metamorphic complexes. The mostly low grade late Paleozoic Eastern Andes Metamorphic Complex (EAMC) crops out to the East of the Meso-Cenozoic South Patagonian batholith (SPB), which intruded the metamorphic complexes.

Facultad de Ciencias Exactas y Naturales) ; Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina). INGEODAV (Instituto de Geofísica “Daniel A. Valencio”)
New multichannel seismic reflection profiles acquired off the Tierra del Fuego Atlantic margin, from the southern part of the Malvinas foreland basin to the inner sector of the Magallanes fold and thrust belt, combined with available commercial profiles and exploration wells, allowed to outline the sedimentary architecture of the foreland basin and the structure of its deformed southern margin.
