Paleogene Magmatism of the Maracaibo Block and its Tectonic SIgnificance
(2019-08-06)
One of the main northern South American geological conundrums has been to establish the tectonic relationship between Caribbean and South American plates during Mesozoic and Cenozoic times. Based on the petrogenetic ...

Extensional tectonics during Late Cretaceous evolution of the Southern Central Andes: Evidence from the Chilean main range at ~35°S
(Elsevier Science, 2018-10)
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 ...
Development of an incipient Paleogene topography between the present-day Eastern Andean Plateau (Puna) and the Eastern Cordillera, southern Central Andes, NW Argentina
(Wiley Blackwell Publishing, Inc, 2020-09-25)
The structural and topographic evolution of orogenic plateaus is an important research topic because of its impact on atmospheric circulation patterns, the amount and distribution of rainfall, and resulting changes in ...
Lower Jurassic to Early Paleogene Intraplate Contraction in Central Patagonia
(Springer International Publishing, 2018)
Breakup and dispersion stages of Gondwana were ruled by crustal extension. In Patagonia, this regime was associated with the opening of extensional basins from the Jurassic onwards, a process that was interrupted by the ...
Chronology of deposition and unconformity development across the Cretaceous Paleogene boundary, Magallanes-Austral Basin, Patagonian Andes
(2019)
The Magallanes-Austral foreland basin preserves an important record of orogenesis and landscape evolution in the Patagonian Andes of Chile and Argentina. Throughout the retroarc foreland basin, a regional disconformity ...

(Asociación Geológica Argentina, 2004-12)
Se describen afloramientos de sedimentitas continentales con restos carbonosos localizados sobre el Río San Pablo en la Estancia La Correntina, provincia de Tierra del Fuego (54° 33´ 01" S, 64° 00´ 20" W). La asociación ...
Tectonic control on the evolution of Maastrichtian-Paleogene synorogenic sequences of the Fuegian Thrust Fold Belt, Argentina.
(Istituto Nazionale di Oceanografia e di Geofisica, 2010-12)
A geological study of the Atlantic coast of Tierra del Fuego between the punta Gruesa (54º 21 S; 66° 38.5 W) and the río Policarpo (54º 39 S; 65º 30 W) (Figure 1), and other sectors of the Fuegian Andes, allowed us to ...
A review of the geology of the Argentinian Fuegian Andes
(Pergamon-Elsevier Science Ltd, 2001-01)
Seven stratigraphic units reflect the tectonic evolution of the Argentinian Fuegian Andes: Basement (Paleozoic-Jurassic); Lemaire Formation (Upper Jurassic); Yahgan-Beauvoir formations (Lower Cretaceous); Cerro Matrero ...
