Trace element 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 several trace elements from samples of the Agly Massif, southern France, and the El Hoyazo dacite dome, southern Spain.The datafiles are presented in multiple sheets that are contained within a single Excel file. The first two sheets show the locations of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) spots. This is followed by a summary of the trace element data. The data itself is organized per minerals, with the data for each mineral presented in a separate Excel sheet.
