Detrital-zircon U-Pb geochronology of the Quebrada del Carrizo Metamorphic Complex and El Jardin Schists and spatially-related granitoids of the Sierra Castillo Batholith
(Servicio Nacional Geología Minerva, 2015)
U-Pb detrital-zircon geochronology of two discrete outcrops of mica schists of the western border of the Domeyko Cordillera in the Region of Atacama, northern Chile, indicates that the maximum age of sedimentation of their ...
An updated scenario for the end-Permian crisis and the recovery of Triassic land flora in Argentina
(Taylor & Francis, 2021-03-04)
The end-Permian crisis was the most severe extinction event in the Phanerozoic. In SouthwesternGondwana, this crisis was related to the development of the Choiyoi Silicic Large Igneous Province. In the Southern Hemisphere, ...
Palynology of late palaeozoic sediments (Tupe Formation) at La Herradura Creek, San Juan province, Argentina
(Taylor & Francis, 2008-12)
Palynomorph assemblages recovered from the Tupe Formation at La Herradura Creek, San Juan province, Argentina, are analysed. The middle section of the sequence includes a marine fossiliferous interval belonging to the ...

Early Permian to Late Triassic batholiths of the Chilean Frontal Cordillera (28°–31°S): SHRIMP U–Pb zircon ages and Lu–Hf and O isotope systematics
(Elsevier, 2014)
One of the major geological units of the Main Andean Range (Frontal Cordillera) of north–central Chile is a
group of composite and heterochronous late Paleozoic–early Mesozoic batholiths that extends for 500 km
roughly ...
A new Early Permian bivalve fauna from the Río Genoa Formation, Patagonia, Chubut Province, Argentina
(Taylor & Francis, 2011-09)
Fourteen Bivalvia species are described from the Lower Permian Río Genoa Formation, exposed in the southern Tepuel-Genoa Basin (Chubut Province, Argentina), of which one, Fletcheripecten genoensis, is new. The studied ...
The Apparent Polar Wander Path for South America during the Permian-Triassic
(Elsevier Science, 2009-04)
Many of the controversies that arise in global reconstructions for Permian-Triassic time could be resolved by taking into account the large latitudinal and counter-clockwise movement of Gondwana during that interval of ...
A new marattialean fern from the Lower Permian of Patagonia (Argentina) with cautionary tales on synangial morphology and pinnule base characters
(University of Chicago Press, 2019-07-22)
Premise of research. The Río Genoa Formation of Argentine Patagonia hosts Early Permian fossil assemblages that document levels of plant diversity rare among coeval floras. Ongoing work to exhaustively characterize the ...
