Geochronological data from the gneissic basement of the Agly Massif, southern France and the xenoliths, and dacitic lava of the El Hoyazo volcano, southern Spain

These are supplementary datafiles for the PhD thesis ''Argon Mobility in the Mid-Lower Continental Crust: Insights from the Agly Massif and El Hoyazo'', which was written by Sander Hoogendoorn in 2024. The datafiles contain measurements of various argon (Ar) isotopes and associated Ar-Ar dates for various samples from El Hoyazo and the Agly Massif.The datafiles are presented in multiple sheets that are contained in a single Excel file. The first two sheets contain meta-data and the data of single-grain fusion analyses from samples of the Agly Massif. The third and fourth sheets contain meta-data and the data of the in-situ laser ablation analyses from the samples of the Agly Massif. The fifth sheet contains meta-data and the data of the in-vacuo crushing analyses from the samples of the Agly Massif. The sixth and seventh sheets contain meta-data and the data of single-grain fusion analyses from samples of El Hoyazo. Finally, the eight sheets contains meta-data and the data of the in-vacuo crushing analyses from the samples of El Hoyazo.
