Abstract
A succession of heterogeneous pyroclastites with contrasted composition (hawaiite-trachyte) and homogeneous intermediate lava flows (benmoreite) is present at Puy de la Nugere (Chaine des Puys, Massif Central, France). Mineralogical disequilibrium assemblages are present in both the explosive en effusive products. Textural, mineralogical and geochemical data on these formations are compatible with a magma mixing model. The origin of the trachyandesitic rocks in the alkaline suite of Chaine des Puys would be controlled by fractional crystallization and magma mixing.
