The central part of the Andes situated between southern Peru and Chile bears 50 active or potentially volcanoes, spread along a 1500 km-long arc. These volcanic structures mostly rise to between ...

Researchers recently discovered a huge chain of extinct volcanoes buried deep below South China that formed when two tectonic ...

Institut de recherche pour le développement The central part of the Andes situated between southern Peru and Chile bears 50 active or potentially volcanoes, spread along a 1500 km-long arc.

For some volcanic arcs, the geochemistry of volcanic rocks erupting above subducted oceanic fracture zones is consistent with higher than normal fluid inputs to arc magma sources. Here we use ...

After years of strenuous effort, the researchers gathered enough samples of lava to analyze the composition of the oxygen isotopes. This information pointed them towards how the lavas were formed and ...
