dc.description.abstract | This contribution deals first new ICP-MS U–Pb zircon ages that indicate Middle- and Late Triassic magmatic episode and tectonometamorphic events, respectively, for the central Patagonia region, instead of a Paleozoic history as previously estimated. The Calcatapul Formation consists of a (meta-) volcano-sedimentary syn-rift sequence deposited unconformably, shortly after the extensional Gondwanide orogenic collapse, over a basement composed of Permian granites. Two 206Pb/238U ages yielded 245.1 ±2.8 and 244.8 ±4.1 Ma to magmatic crystallization of ignimbrites, along with another weighted mean of 226.7 ±4.4 Ma interpreted as the age of the tectonometamorphic event D1-M1 affecting the Calcatapul sequence. U–Pb ages open new insights into the tectonomagmatic evolution of the area because the syn-rift wedge deposited in the Uribe and Yancamil half- grabens under the extensional tectonic regime was then inverted along the basin-bounding faults like the Yancamil fault. Inversion tectonics involved reverse fault-related uplift against a buttress of the rigid granitic block, and under dynamic greenschist-to-amphibolite facies metamorphic conditions, before the Late-Triassic granitic magmatism of the Lipetr´en Suite took place. The pre-rift granitic basement represents the southern extension of the main magmatic phase of Choiyoi Province in Patagonia, whereas the Middle Triassic recorded the extensional, post-Choiyoi magmatism. The local, compressive D1 event punctuated an overall widespread lithospheric extension that leads to Gondwana breakup since the earliest Jurassic times. | es_ES |
