Mineral / melt partitioning of trace elements during hydrous peridotite partial melting
This experimental study examines the mineral/ melt partitioning of incompatible trace elements among high-Ca clinopyroxene, garnet, and hydrous silicate melt at upper mantle pressure and temperature conditions. Experiments were performed at pressures of 1.2 and 1.6 GPa and temperatures of 1,185 to 1,370 C. Experimentally produced silicate melts contain up to 6.3 wt% dissolved H2O, and are satur...
متن کاملEffect of water on the fluorine and chlorine partitioning behavior between olivine and silicate melt
Halogens show a range from moderate (F) to highly (Cl, Br, I) volatile and incompatible behavior, which makes them excellent tracers for volatile transport processes in the Earth's mantle. Experimentally determined fluorine and chlorine partitioning data between mantle minerals and silicate melt enable us to estimate Mid Ocean Ridge Basalt (MORB) and Ocean Island Basalt (OIB) source region conc...

متن کاملAbundance and Partitioning of OH in a High- pressure Magmatic System: Megacrysts from the Monastery Kimberlite, South Africa
Concentrations of OH, and major and trace elements were determined in a suite of mantle-derived megacrysts that represent the crystallization products of a kimberlite-like magma at 5 GPa and 1400---1100 C. OH concentrations, determined by singlecrystal Fourier transform infrared spectroscopy, display the following ranges (ppmw H2O): olivine 54---262, orthopyroxene 215---263, garnet 15---74, cli...
متن کاملThermodynamic models for eclogitic mantle lithosphere1
Cratonic mantle eclogite xenoliths occur with diamond-bearing kimberlite. The modes and mineral compositions of eclogite contain important information on their origin, physical-chemical conditions of formation, and their geophysical properties. We have used the pseudosection option of the program PERPLEX to explore how mineral assemblage, abundance, and composition vary with bulk composition, t...
