Tectonic controls on the origin and segmentation of the Cascade Arc, USA
The magmatic response above subducting ocean lithosphere can range from weak to
vigorous and from a narrow zone to widely distributed. The small and young Cascade Arc …

A global assessment of the controls on the fractionation of arc magmas
During the differentiation of arc magmas, fractionating liquids follow a series of cotectics,
where the co‐crystallization of multiple minerals control the melt compositional trajectories …
