Primary silicate-melt inclusions in phenocrysts from Vesuvius-Terzigno scoria and from leucite-tephrite, latite, K-basalt, and trachybasalt Roccamonfina lavas have been studied in order to investigate magma crystallization and evolution, and to characterize the composition of parental magmas. Reheated clinopyroxene-hosted silicate-melt inclusions define a less evolved magma composition compared with their corresponding bulk rock. For Roccamonfina silicate-melt inclusion major, minor-element and volatile variations display three different compositional trends, identified as potassic (KS), high potassic (HKS) and intermediate-K, indicating derivation from different parental melts.
