Abstract
Trondhjemite and quartz diorite xenoliths ejected in recent Icelandic eruptions are believed to be derived from plagiogranites within layer 3, formed by fractional crystallisation of basaltic magmas in the lower crust. Evidence indicates that rift jumping to older crust can lead to partial melting of plagiogranites at depth and their eruption as rhyolitic magmas.
