Summary

High-precision CA-ID-TIMS (Chemical Abrasion Isotope Dilution Thermal Ionization Mass Spectrometry) Uranium-Lead geochronology of zircon, extracted from igneous plutonic and mineralised porphyry intrusions in the Rio Blanco-Los Bronces Cu Porphyry area, Chile. Eleven parent samples cover an age range of ca. 14 Ma to ca. 5 Ma. Sample Identifiers correspond to the NERC Highlight topic consortium project FAMOS (From Arc Magmas to Ores) samples from the Natural History Museum component of the project and Large et al.(2024) J. Pet, where full rock types, geo-references, petrography, and geochemistry of parent samples can be found in addition to zircon Cathodoluminesence and SEM characterization of zircon of samples, and the corresponding zircon trace element analyses (inclusive of U-Pb) by laser ablation ICPMS. This data provides insights into the crystallisation of zircon and timescales of porphyry copper deposits.
