A comprehensive petrological and geochemical dataset is reported in order to define the thermo-compositional characteristics of Ti (Fe)-enriched picrite–basalt lavas (HT2, TiO 2 3–7 wt%), erupted close to the axial zone of the inferred Afar mantl

Coexistence of alkaline-carbonatite complexes and high-MgO CFB in the Parana-Etendeka province: Insights on plume-lithosphere interactions in the Gondwana realm

Autor: Luigi Beccaluva, Claudio Natali, Gianluca Bianchini, Franca Siena

A careful review of petrological and geochemical data on the Parana-Etendeka igneous province is reported, with particular attention being devoted to the relationships between high-MgO CFB (tholeiitic basalts-picrites) and nearly coeval alkaline-carb

Geochemistry and petrology of the Kermanshah ophiolites (Iran): Implication for the interaction between passive rifting, oceanic accretion, and OIB-type components in the Southern Neo-Tethys Ocean

Autor: Emilio Saccani, Khalil Allahyari, Gianluca Bianchini, Luigi Beccaluva

The Mesozoic southern branch of the Neo-Tethys Ocean was located between the Arabian shield and the Sanandaj–Sirjan continental block of Iran. The Kermanshah ophiolitic complex crops out in the Main Zagros Thrust Zone in Iran and consists of severa
