Crustal Structure of the Middle Mariana Arc-Back-Arc System
… im zentralen Marianen-Inselbogen–Back-Arc-System, auf die subduzierende Platte vor der Küste von Costa Rica sowie auf Fluidsysteme im nördlichen Schwarzen Meer. Die seismischen Daten zeigen, dass sich im Donaufächer des Schwarzen Meeres selbst hydratationsarme Randbecken detailliert …

Volatile chemistry, and nitrogen sources and fluxes, in subduction zones : insights from the Izu-Bonin-Mariana Arc
… from the active volcanic front of the Izu-Bonin-Mariana (IBM) arc was undertaken in order to investigate the sources, flux, and mass balance of nitrogen across this 'cool' convergent margin. The IBM arc is an ideal location to study volatile recycling in subduction zones as it is an intra-oceanic …

Mantle Wedge Evolution beneath the Northern Mariana Forearc
… convergent systems on the Earth – the Izu-Bonin-Mariana arc (IBM). To understand the geochemical characteristics of a supra-subduction zone mantle wedge and how it has evolved in response to subduction of the Pacific Plate, forearc peridotites (dunites and harzburgites) were collected by dredging …

Magmatic volatiles at rifts and arcs: Sources and fractionation effects
… 3 and 4 are studies of S degassing at rift and arc volcanoes through the use of S isotopes. Sulfur is extremely important for eruption prediction because SO2 is the only gas routinely measured remotely at active volcanoes. Explosive eruptions can inject large quantities of S into the …
