This is significant as the Neogene volcanic regi n of SE Spain hosts a wide variety of mineral deposits making up a metallogenetic belt from Cartagena to Cabo de Gata: Pb-Zn (± Ag,Sb) (Mazarron, Sierra Almagrera), Sb-Hg-Ba (±Au) (Valle del Azogue), Fe-Mn-Ba-Ag (Las Herrerías), native Au (Rodalquilar). The current exploitation of the garnets as industrial raw material is also described.spajournal articlehttps://sociedadgeologica.org/publicaciones/geogaceta/geogaceta-22-1997/open access549.621.9(460)GarnetsMineral explorationRaw materialSE SpainMineralogía (Geología)2506.11 Mineralogía
