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

A critical review of the available multidisciplinary data on the Parana-Etendeka Province allows for the reconciliation of the controversial aspects of its origin in a coherent tectonomagmatic scenario, in which continental flood basalt (CFB) magmati

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

Manuella et al. (2015) emphasize that the Hyblean xenolith suite includes only ultramafic (peridotites and pyroxenites) and mafic (gabbros s.l.) lithotypes, whereas felsic rocks are not observed. On this ground, they attest that rocks having a “con

The Betic Ophiolites consist of numerous tectonic slices, metric to kilometric in size, of eclogitized mafic and ultramafic rocks associated to oceanic metasediments, deriving from the Betic oceanic domain. The outcrop of these ophiolites is aligned
