Abstract
The Vulture complex is made up of foiditic, tephritic, phonolitic-trachytic and phonolitic products.
New rock analyses have been performed in order to ascertain whether the various rock types derive from a unique parental magma and, if so, to define its nature.
The data presented support that the Vulture suite originated from a foiditic melt which had differentiated at low pressures. The main process determining the foidite → → tephrite → phonolitic trachyte evolution seems to be the crystal fractionation of mainly clinopyroxenes, and opaques, with the contribution of plagioclases and haüyne too in the tephrite → trachyte evolution. Additionary role must have been played by a mixing of melts at different evolution stages occurred in a shallow seated magma chamber.
