Abstract: New U–Pb and Lu–Hf detrital zircon data together with whole-rock geochemical and Sm–Nd data were obtained for paragneisses of the Austroalpine basement south of the Tauern Window. Geochemically immature metasediments of the Northern–Defereggen–Petzeck (Ötztal–Bundschuh nappe… read more here.

DOI: 10.1016/j.precamres.2021.106115
Abstract: Abstract In this contribution we investigate the exhumation T-t path of a nappe system located in the southernmost edge of the Brasilia Orogen, southeast Brazil, developed during the West Gondwana assembly. The allochthons represent an… read more here.
