Learn how subduction zones become enriched in gold through repeated melting of Earth's mantle.

Earth's "gold kitchen" lies deep beneath the seafloor. Island arcs, whose volcanoes form above subduction zones where one ...

This study is led by Prof. Zhong-Hai Li (University of Chinese Academy of Sciences). The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates ...

Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the ...

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...
