Pyroxenitization of dunites in the lower continental crust: evidence from the Ivrea Mafic Complex (Italian Alps)

Autor: Davide Mariani, Maria Rosaria Renna, Riccardo Tribuzio

The processes driving the chemical differentiation of mantle-derived magmas emplaced at deep levels of the continental crust are mostly unknown. Melt compositions may be modified through interplay of fractional crystallization, magma mixing, crustal

The Jurassic Chenaillet ophiolite in the Western Alps consists of a gabbro–mantle association exhumed to the seafloor through detachment faulting and partly covered by basaltic lavas. One of the Chenaillet gabbroic bodies includes mylonites that ar

Chemical signature of migmatite-related melts migration in lower mafic crust: mineral geochemistry and zircon dating constraints (Variscan lower crust, SW Calabria, Italy)

Autor: Alfredo Caggianelli, Antonio Langone, Maria Rosaria Renna, Giacomo Prosser

This work deals with a portion of the Variscan lower to intermediate crust exposed in the Palmi area (SW Calabria, Italy). It mainly consists of amphibole-bearing tonalite and migmatitic paragneiss. The latter shows a peak metamorphic assemblage of b

Fragments of Jurassic oceanic crust exposed in the Northern Apennine (Italy) are either associated with continental lithosphere material (External Ligurian ophiolites), or bear structural and compositional resemblances to slow spreading ridge crust (

The gabbroic bodies from the Jurassic Ligurian ophiolites are structurally and compositionally similar to the gabbroic sequences from the oceanic core complexes of the Mid Atlantic Ridge. Initial cooling of the Ligurian gabbros is associated with loc
