Carbonatitic melts along the solidus of model lherzolite in the system CaO-MgO-Al2O3-SiO2-CO2 from 3 to 7 GPa
Abstract We have experimentally determined the solidus position of model lherzolite in the system CaO-MgO-Al2O3-SiO2-CO2 (CMAS.CO2) from 3 to 7 GPa by locating isobaric invariant points where liquidExpand
The Continuum of Primary Carbonatitic-Kimberlitic Melt Compositions in Equilibrium with Lherzolite: Data from the System CaO-MgO-Al2O3-SiO2-CO2 at 6 GPa
-free CMAS solidus. The aimof this study was to trace the compositional path of thisline and determine the compositions of coexisting phases.The advantage of this approach is that bulkExpand
Continuous Gradations among Primary Carbonatitic, Kimberlitic, Melilititic, Basaltic, Picritic, and Komatiitic Melts in Equilibrium with Garnet Lherzolite at 3–8 GPa
Multianvil melting experiments in the system CaO–MgO–Al2O3– SiO2–CO2 (CMAS–CO2) at 3–8GPa, 1340–1800 � C, involving the garnet lherzolite phase assemblage in equilibrium with CO2-bearing melts, yieldExpand
Liquidus phase relations on the join diopside-forsterite-anorthite from 1 atm to 20 kbar: Their bearing on the generation and crystallization of basaltic magma
In the system CaO-MgO-Al2O3-SiO2, the tetrahedron CaMgSi2O6(di)-Mg2SiO4(fo)-SiO2-CaAl2 SiO6(CaTs) forms a simplified basalt tetrahedron, and within this tetrahedron, the plane di-fo-CaAl2Si2O8(an)Expand
Generation of mid-ocean ridge basalts at pressures from 1 to 7 GPa
We propose a model for the generation of average MORBs based on phase relations in the CaO-MgO-Al2O3-SiO2-CO2 system at pressures from 3 to 7 GPa and in the CaO-MgO-Al2O3-SiO2-Na2O-FeO (CMASNF)Expand
Melting Behavior of Simplified Lherzolite in the System CaO-MgO-Al2O3-SiO2-Na2O from 7 to 35 kbar
Phase equilibrium data have been collected for isobarically univariant melting of simplified lherzolite compositions in the system CaO-MgO-Al2O3-SiO2-Na2O over a pressure range of 7-35 kbar. TheseExpand
Garnet-bearing Xenoliths from Salt Lake Crater, Oahu, Hawaii: High-Pressure Fractional Crystallization in the Oceanic Mantle
The focus of this study is a suite ofgarnet-bearing mantle xenoliths from Oahu, Hawaii. Clinopyroxene, olivine, and garnet constitute the bulk of the xenoliths, and orthopyroxene is present in smallExpand
Melting relations of model lherzolite in the system CaO‐MgO‐Al2O3‐SiO2 at 2.4–3.4 GPa and the generation of komatiites
Isobarically invariant phase relations in the CaO-MgO-Al2O3-SiO2 system (CMAS) involving the lherzolite phase assemblage in equilibrium with liquid have been determined at 2.4–3.4 GPa. These phaseExpand
