Abstract

The Catalan Volcanic Zone (CVZ) in northeastern Spain is an intraplate alkaline volcanic region linked to the Western Mediterranean's opening and the European Rift System's development. Volcanic activity began in L'Empordà (>12--8 Ma), progressed to La Selva (7.9--1.7 Ma), and culminated in the Garrotxa Volcanic Field (<0.7--0.01 Ma). Despite decades of research, key aspects remain unclear, including magma plumbing systems' evolution, ascent mechanisms, and a detailed chronology of volcanism. Addressing these gaps requires consolidated geochemical, petrological, and geochronological data, which have remained scattered and unintegrated. This study introduces the CatVolc (Catalan Volcanism) database, unifying geochemical and geochronological data for volcanic materials in the CVZ. It includes analyses of 405 rock samples (296 juvenile magmatic rocks, 109 xenoliths) and radiometric/thermoluminescence ages from 57 rocks, 4 paleosols, and 1 sediment sample. Each entry provides information on sampling sites, lithology, whole-rock compositions, isotopic ratios, mineral chemistry, and/or radiometric/thermoluminescence dating. Preliminary analyses of CatVolc reveal critical knowledge gaps and suggest future research directions. This database is essential for understanding magmatic systems and volcanic activity within the CVZ, particularly the Garrotxa Volcanic Field, aiding hazard assessment and improving insights into future eruptions.
