Rapid shifting of a deep magmatic source at Fagradalsfjall volcano, Iceland
Recent 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 that tra...

Recent 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 that trace the origin, evolution and transport of melts in the uppermost mantle and lowermost crust(6,7). Here we present unique insights into processes occurring in this zone from integrated petrologic and geochemical studies of the 2021 Fagradalsfjall eruption on the Reykjanes Peninsula in Iceland. Geochemical analyses of basalts erupted during the first 50 days of the eruption, combined with associated gas emissions, reveal direct sourcing from a near-Moho magma storage zone. Geochemical proxies, which signify different mantle compositions and melting conditions, changed at a rate unparalleled for individual basaltic eruptions globally. Initially, the erupted lava was dominated by melts sourced from the shallowest mantle but over the following three weeks became increasingly dominated by magmas generated at a greater depth. This exceptionally rapid trend in erupted compositions provides an unprecedented temporal record of magma mixing that filters the mantle signal, consistent with processing in near-Moho melt lenses containing 10(7)-10(8) m(3) of basaltic magma.
