Periodic Reporting for period 1 - OXYGEN (The redox evolution of arc magmas: from the oxygenation of the Earth’s atmosphere to the genesis of giant hydrothermal ore deposits)

Arc magmatism at subduction zones is responsible for much of the mass transfer of chemical elements between the Earth’s lower and upper spheres. Arc magmas are significantly more oxidized and richer in volatile elements than other voluminous magma types on Earth. These...
