Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left an imprint on volcanic rocks formed in island arcs.

Scientists have uncovered the secret origins of gold beneath the ocean floor. A study published in Communications Earth & Environment reveals that gold in volcanic island arcs forms not through a ...

Volcanic island arcs form above subduction zones where an oceanic plate descends beneath another plate, generating magmas that rise to build submarine edifices and emergent islands. Magma composition ...

Island arc systems arise where an oceanic plate descends beneath another plate, generating a volcanic chain parallel to a deep-sea trench. Fluids released from the subducting slab induce melting in ...
