An experimental study of the effect of Ca upon garnet-clinopyroxene Fe-Mg exchange equilibria
AbstractA series of basaltic compositions and compositions within the simple system CaO-MgO-FeO-Al2O3-SiO2 have been crystallized to garnetclinopyroxene bearing mineral assemblages in the range 24–30
High pressure experimental calibration of the olivine-orthopyroxene-spinel oxygen geobarometer: implications for the oxidation state of the upper mantle
AbstractSynthetic spinel harzburgite and lherzolite assemblages were equilibrated between 1040 and 1300° C and 0.3 to 2.7 GPa, under controlled oxygen fugacity (fO2). fO2 was buffered with
An experimental determination of primary carbonatite magma composition
Carbonatites are uncommon carbonate-rich rocks usually found in continental intra-plate regions and often associated with rifting. There has been much debate as to whether carbonatite magmas are
Stability and chemical composition of pargasitic amphibole in MORB pyrolite under upper mantle conditions
Abstract The stability field of pargasitic amphibole in a model mantle composition (MORB pyrolite) has been experimentally determined for a fixed water content. A solidus for a pargasite-bearing
Anhydrous melting of peridotite at 0–15 Kb pressure and the genesis of tholeiitic basalts
The anhydrous melting behaviour of two synthetic peridotite compositions has been studied experimentally at temperatures ranging from near the solidus to about 200° C above the solidus within the
