TL;DR: In this article, a thermobarometer based on magma Si and Mg contents was used to estimate the pressures and temperatures of basaltic magma generation on Earth and other terrestrial planets.

TL;DR: The redox state of arc magmas is tracked from mantle source to emplacement in the crust on the basis of copper’s (Cu) affinity for reduced sulfur phases, suggesting that the formation of sulfide-bearing cumulates under reducing conditions may be a critical step in continent formation.

TL;DR: In this paper, the authors show that continents are underlain by highly melt-depleted peridotites, which result in a chemically distinct boundary layer that is intrinsically buoyant and strong (owing to dehydration).

TL;DR: In this article, V/Sc ratios in primitive arc lavas from the Cascades magmatic arc are correlated with fluidmobile elements (e.g. Ba and K), indicating that fluids may subtly influence fO2 during melting.

TL;DR: In this article, the authors explore the possibility of using Zr and P systematics to evaluate the importance of some of these processes, such as direct melting of the mantle at water-saturated conditions, partial remelting of altered basaltic crust, crystal fractionation of arc basalts in crustal magma chambers, and mixing of mafic magmas with high Si crust or magmas, e.g., dacite-rhyolite.
