The earth's mantle is degassed along mid-ocean ridges, while rehydration and possibly recarbonaton occurs at subduction zones. These processes the speciation of C-H-O fluids in are related to oxidation state peridotite. Peridotite xenoliths from continental localities exhibit an oxygen fugacity (fo(2)) range -1.5 +1.5 log units relative FMQ (fayalite-magnetite-quartz) buffer. lowest values zones extension. Highly oxidized (fo(2) greater than FMQ) come regions recent or acive (for example,...
As part of a project to investigate the volatilities so-called “moderately volatile elements” such as Zn, In, Tl, Ga, Ag, Sb, Pb, and Cl during planetary formation, we began by re-calculating condensation temperatures these elements from solar gas at 10-4 bar. Our calculations highlighted three areas where currently available estimates temperature could be improved. One is nature mixing behavior many important trace when dissolved in major condensates silicates, Fe-rich metals, sulfides....
The extent to which sulfur dissolves in silicate melts saturated an immiscible sulfide phase is a fundamental question igneous petrology and plays primary role the generation of magmatic ore deposits, volcanic degassing, planetary differentiation. In systems, can be described as FeS-NiS-CuS0.5 solutions with Fe/(Fe+Ni+Cu) significantly less than 1. Despite presence Ni Cu sulfide, however, most experimental studies date have concentrated on effects melt composition solubility used essentially...

We report new findings related to sample 14161,7373, the first analyzed limar intrusive rock show textural evidence for formation of granitic material by silicate liquid immiscibility (SLI) and geochemical separation that material, at least on a small scale, from mafic residua. Ion microprobe analyses rare-earth element (REE) concentrations in silicates record compositional evolution this late-stage assemblage. For whose bulk assemblage, whitlockite monzogabbro, has REE ~5-6× KREEP levels,...
