Along 1,100 kilometers, from Mexico to Costa Rica, lies the Central American volcanic arc, where the variety of magma types make for a geological paradise. By Pablo Fonseca Q. / Knowable Magazine ...

Iran’s Pickaxe Mountain, or Kuh-e Kolang Gaz La in Persian, is part of a volcanic arc that formed tens of millions of years ...

Earth's "gold kitchen" lies deep beneath the seafloor. Island arcs, whose volcanoes form above subduction zones where one oceanic plate sinks beneath another, are often particularly rich in gold. The ...

Scientists say they've discovered a 400-mile chain of extinct and fossilized volcanoes beneath southern China. The volcanoes, the researchers claim, were likely formed when two major tectonic plates ...

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 ...

The Aegean Arc represents a dynamic convergent boundary where the African plate subducts beneath the Eurasian plate. This geodynamic setting has given rise to a chain of volcanic centres characterised ...
