Mid- to Late Cambrian docking of the Río de la Plata craton to southwestern Gondwana: Age constraints from U-Pb SHRIMP detrital zircon ages from Sierras de Ambato and Velasco (Sierras Pampeanas, Argentina)

Verdecchia, Sebastian O.; Casquet, Cesar; Baldo, Edgardo; Pankhurst, Robert J; Rapela, Carlos W; Fanning, Christopher; Galindo, Carmen


The Early Palaeozoic stratigraphy and tectonic history of the Eastern Sierras Pampeanas of central Argentina are complicated by metamorphism and deformation resulting from the Pampean (545-510 Ma) and Famatinian (490-440 Ma) orogenies. We report U-Pb sensitive high-resolution ion microprobe dating of detrital zircons in two metasedimentary successions exposed at Quebrada de La Cébila (c. 28°45'S, 66°25'W): the Ambato and the La Cébila metamorphic complexes. The Ambato zircons record age peaks...[Show more]
