A subduction influence on ocean ridge basalts outside the Pacific subduction shield
The plate tectonic cycle produces chemically distinct mid-ocean ridge basalts and arc
volcanics, with the latter enriched in elements such as Ba, Rb, Th, Sr and Pb and depleted in …

Sulfur isotope and trace element systematics in arc magmas: seeing through the degassing via a melt inclusion study of Kyushu Island volcanoes, Japan
Sulfur is a minor element in magmas but one of the major volatile elements released in
volcanic systems, from the magma to the fluid phase upon ascent. Not only are sulfur gasses …
