Rapid shifting of a deep magmatic source at Fagradalsfjall volcano, Iceland ...
AbstractRecent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport 1–4 , important characteristics of mid-ocean ridge magmatism 1,5 . A consequence of such shallow crustal processing of magmas 4,5 is the overprinting of signatures t...
