Changing lake dynamics and sequence stratigraphy of synrift lacustrine strata in a half-graben: An example from the Triassic Ischigualasto-Villa Unión Basin, Argentina
(Wiley Blackwell Publishing, Inc, 2007-12)
Well-exposed Triassic rift strata from the Ischigualasto-Villa Unión Basin (NW Argentina) include a 80 to ca 515 m thick lacustrine-dominated package that can be correlated across a half-graben using key stratigraphic ...
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, ...

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) ...
