Major and trace element and isotopic evidence indicates that the basalts represent several liquid lines of descent, each equilibrated at crustal pressures. All Silali basalts...

At the same time, lagoonal evaporites were deposited in the middle of the Western Carpathians ( Vass et al . 1979 ); therefore an island surrounded...

This new model obviates the requirement for mixing of mantle-derived magmas or the high temperatures required for generation of large volumes of melt from mafic protoliths (e.g., Petford and Gallagher, 2001 ). The HMB comprises a tilted crustal slab of an island arc obducted...
