TL;DR: In this paper, the authors evaluate the combined systematics of volatiles (H2O, S, Cl, F) and incompatible trace elements in their parental magmas and mantle sources to constrain thermal conditions of mantle melting, and estimate the composition of slab-derived components.

TL;DR: In this paper, the authors demonstrate that nearly dry melt inclusions from Galapagos Plateau basalt can gain up to 2.5 wt.% of water if they are placed for 2 days in a water-bearing melt at 200 MPa and 1140 °C.

TL;DR: In this article, oxygen isotope compositions of 34 adakites, high-Mg andesites, and lavas suspected to contain abundant slab and sediment melts from the Western and Central Aleutians, the Andes, Panama, Fiji, Kamchatka, Setouchi (Japan), and the Cascades are measured and calculated values of olivine phenocrysts in these samples vary between 4.88 and 6.78

TL;DR: In this paper, the solubility of H2O and CO2-bearing fluids in tholeiitic basalts has been investigated experimentally at temperature of 1250 °C and pressures of 50, 100, 200, 300, 400 and 500 MPa.

TL;DR: This paper used melt inclusions in olivine (Fo90-64) from 11 localities in Guatemala, Nicaragua and Costa Rica along the Central American Volcanic Arc to constrain combined systematics of major and trace elements and volatile components (H2O, S, Cl, F) in parental melts and estimate volcanic fluxes of volatile elements.
