Legora Woitech Hecksher, Ana Clara; Dantas, Elton L: Sm–Nd isotopic data for rock samples from the Araçuaí Orogen, SE Brazil [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.989760 (dataset in review)
Abstract:
This dataset contains Sm–Nd isotopic compositions measured (108 new results) from rock samples analyzed in 2022 at the Laboratory of Geodynamic, Geochronological, and Environmental Studies (LEGGA) of the University of Brasília (UnB), Brazil. Sample preparation and analysis followed the procedures described by Gioia and Pimentel (2000). The Sm and Nd isotopic ratios were measured using a Thermo Scientific TRITON Plus TIMS thermal ionization mass spectrometer. The model and εNd values were relative to the depleted mantle, following the equations presented by DePaolo et al. (1991) for the single-stage model. The resulting data are presented as supplementary material.
