Short summary
We present a petrological⁠–geochemical investigation of peridotites of magmatic origin from the Ivrea⁠–Verbano Zone (Italian Alps), a large-scale section of lower continental crust. The main purpose is to provide new insights into the processes governing the evolution of primitive mantle magmas. We propose that studied peridotites were formed by reaction of a melt-poor olivine-rich crystal mush, or a pre-existing peridotite, with upward-migrating melts possessing a substantial crustal component.
