文摘
- •
We present major oxide content and Sr–Nd isotopic data determined on bulk rock, groundmass and separated phenocrysts.
- •
We present major and volatile element contents of clinopyroxene-hosted melt inclusions.
- •
Nisida eruption was triggered by a shoshonite–latite volatile-rich magma with an isotopic composition like Astroni 6 event.
- •
Magma mingling/mixing, and/or entrapment of antecrysts prior to the Nisida eruption can explain the isotopic variation.
