UPbGeoChronSPZ2024: U-Pb data from the South Portuguese Zone, Iberian MassifZenodo

Abstract

Comprehensive isotopic databases of a particular geotectonic domain are valuable resources for geoscientists to develop geological models, such as paleogeographic and tectono-magmatic evolution models. The UPbGeoChronSPZ2024 is an open-access dataset of U-Pb isotopic analyses in minerals, primarily zircon, from igneous and siliciclastic rocks of the South Portuguese Zone, a Laurussian affinity terrain hosting a world-class metallogenic region, the Iberian Pyrite Belt. The dataset includes isotopic measurements and the location of the samples in WGS84 coordinates and it can be easily coupled with other regional or global datasets, making its value beyond its regional character. Furthermore, the dataset includes cutting-edge calculation methods for ages and discordances that allows geoscientists to test different outcomes.
