Magmatic to hydrothermal metal fluxes in convergent and collided margins
JP Richards - Ore Geology Reviews, 2011 - Elsevier
Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

The generation and evolution of the continental crust
The continental crust is the archive of the geological history of the Earth. Only 7% of the crust
is older than 2.5 Ga, and yet significantly more crust was generated before 2.5 Ga than …

How important is the role of crystal fractionation in making intermediate magmas? Insights from Zr and P systematics
CTA Lee, O Bachmann - Earth and Planetary Science Letters, 2014 - Elsevier
Most magmatism on Earth forms by direct melting of the mantle, generating basalts at the
low silica end of the terrestrial compositional spectrum. However, most subduction zone …

Why do mafic arc magmas contain∼ 4 wt% water on average?
The last 15yr have seen an explosion of data on the volatile contents of magmas parental to
arc volcanoes. This has occurred due to the intense study of melt inclusions trapped in …
