Volatile-rich tephritic melts represent the most primitive compositions at Vesuvius. Recent eruptions (1906, 1944) record the multiple injections of such compositions at shallow levels, and their crystallization and mixing. Plinian magma chambers (eg, the 79 AD Pompei eruption) grow from the periodic supply of K-rich mafic melts.
