L’île de Panarea fait partie d’un large complexe volcanique qui s’est principalement développé entre 155 et 118 ka. Les protolithes sélectionnés sont de compositions andésitiques à dacitiques et issus des séries calco-alcalines riches en potassium. Les phases minérales majeures sont le plagioclase, le clinopyroxène, l’orthopyroxène, l’olivine et l’amphibole. Les textures sont porphyriques et gloméropophyriques. Les protolithes montrent un comportement d’arc volcanique avec un enrichissement en LILE (Large Ion Lithophile Elements) par rapport aux HFSE (High Field Strength Elements). Une forte activité hydrothermale touche ces roches, produisant des néoformations sous forme de séquences paragénétiques : (1) des veines de sulfures et sulfates massifs (marcassite-silice-alunite-baryte-gypse-halite), (2) des précipitations d’alunite et de kaolinite (alunite-silice-kaolinite-montmorillonite) et (3) des veines de sulfures et sulfates oxydées (silice-hématite-goethite-alunite-kaolinite-montmorillonite-gypse), soumises à l’altération supergène. Les profils d’altération montrent un enrichissement global en LILE/HFSE, indiquant une altération de surface, et le lessivage de certains éléments (Dy, Y, Yb, Lu). Un schéma d’altération est présenté pour les différentes paragenèses.
