Tectonic Setting of the Tordillo Formation in the Aconcagua Fold-and-Thrust Belt
(Springer, 2020)
At the northwestern Mendoza province, the Mesozoic infill of the Neuquén Basin is tectonically repeated in the Aconcagua fold-and-thrust belt. Particularly, the Tordillo Formation (commonly associated with the Kimmeridgian) ...
Formación Laguna Tordillo: Volcanismo dacítico eoceno en el Macizo del Deseado, provincia de Santa CruzLaguna Tordillo Formation: Eocene dacitic volcanism in the Deseado Massif, Santa Cruz province
(Asociación Geológica Argentina, 2004-08)
Se determinó una nueva entidad formacional para la provincia geológica Macizo del Deseado. Se trata de rocas volcánicas melanocráticas que se presentan como dos afloramientos en inmediaciones de la laguna Tordillo, en el ...
Hierarchy of bounding surfaces in aeolian sandstones of the Tordillo Formation (Jurassic). Neuquén Basin, Argentina
(Universitat de Barcelona. Facultat de Geologia, 2005-12)
The Tordillo Formation is a continental clastic unit deposited in the Neuquén Basin during the Late Jurassic. This paper discusses the stratigraphy of the succession outcropping at the Quebrada del Sapo, with emphasis on ...
U-Pb detrital zircon ages of upper jurassic continental successions: Implications for the provenance and absolute age of the jurassic-cretaceous boundary in the Neuquén Basin
(Geological Soc Publ House, 2015-04-23)
New U-Pb detrital zircon ages are presented for the Tordillo Formation. The ages indicate that the most important source region of sediment supply was the Jurassic Andean arc (peaks at c. 144, 153 and 178 Ma), although two ...
Anatomy and facies distribution of terminal lobes in ephemeral fluvial successions: Jurassic Tordillo Formation, Neuquen Basin, Argentina
(Wiley Blackwell Publishing, Inc, 2020-08)
In terminal fluvial-fan systems, characteristic proximal to distal variations in sedimentary architectures are recognized to arise from progressive downstream loss of water discharge related to both infiltration and ...
Architecture and development of the alluvial sediments of the Upper Jurassic Tordillo Formation in the Cañada Ancha Valley, northern Neuquén Basin, Argentina
(Elsevier Science, 2009-07)
The Upper Jurassic Tordillo Formation at Cañada Ancha area, northern Neuquén Basin, Argentina, comprises a multi-stage suit of predominantly alluvial sediments that is heterolithic in nature. In that suit, several lithofacies, ...
Controls on Deposition of the Tordillo Formation in Southern Mendoza (34°–36° S): Implications for the Kimmeridgian Tectonic Setting of the Neuquén Basin
(Springer, 2020)
The Tordillo Formation is a continental succession of red beds deposited in the Neuquén basin during the Kimmeridgian. Based on sedimentological and structural evidence we document an extensional setting between 34˚ and ...
Edades U-Pb en circones detríticos de la Formación Tordillo en la cuenca Neuquina, centro-oeste de Argentina: implicancias en la edad absoluta del límite Jurásico-Cretácico.U-Pb detrital zircons ages of the Tordillo Formation in the Neuquén Basin, central-western Argentina: implications in the absolute age of the Jurassic-Cretaceous boundary
(Academia Nacional de Ciencias Exactas, Físicas y Naturales, 2016-12)
La propuesta de este trabajo es presentar y discutir la importancia de los datos U-Pb en circones detríticos recientemente obtenidos por varios autores en la Formación Tordillo, con especial énfasis en las edades de circones ...
