Evidence from high‐Ni olivines for a hybridized peridotite/pyroxenite source for orogenic andesites from the central Mexican Volcanic Belt

Subduction zone magmatism produces calc‐alkaline andesite melts that combine the high SiO 2 , Na 2 O, and K 2 O abundances of the differentiated continental crust with low FeO, FeO/MgO, and TiO 2 typical of melts from depleted mantle. Ni‐rich olivines in basaltic andesites and andesites of the centr... View More
