Abstract

During the past 10 ka, the products of volcanic activity in the Phlegraean Fields have exhibited a compositional variation from trachybasalt to peralkaline phonohte, which is interpreted as resulting from differentiation dominated by crystal-liquid fractionation in a shallow magma chamber. Whole-rock (super 87) Sr/ (super 86) Sr data show a regular trend with the less differentiated rocks having the most radiogenic Sr. There is no systematic variation in Neodymium isotopes. The isotopic variations are considered to be the result of a pre-eruptive process in the magma chamber, which was affected in its deeper part by a combined process of crystal fractionation and fluid-magma interaction.
