Whole-rock geochemical and isotopic compilation of Ediacaran–Cambrian granitoids from the Rio Grande do Norte Domain, Borborema Province (NE Brazil)

This collection compiles whole-rock geochemical and isotopic data from Ediacaran–Cambrian magmatic suites of the Rio Grande do Norte Domain (Borborema Province, NE Brazil). The dataset integrates newly generated and legacy data (Rb–Sr, Sm–Nd, major and trace elements) systematically compiled from published and unpublished sources. All isotopic ratios were recalculated to common reference ages using consistent decay constants and CHUR parameters to ensure internal comparability. The collection includes standardized sample metadata (coordinates, lithology, tectonic setting, magmatic suite classification), analytical metadata, and calculated parameters such as εNd(t), TDM model ages, and elemental ratios. This dataset provides a comprehensive isotopic and geochemical framework for post-collisional magmatism in the Rio Grande do Norte Domain of Borborema Province and is intended to support regional tectonic interpretations, petrogenetic modeling, and global comparative studies of Western Gondwana magmatism.
