Sodium partitioning between clinopyroxene and silicate melts

Journal of Geophysical Research: Solid Earth, 1995
We present a quantitative model for Na partitioning between clinopyroxene and silicate melt, applicable in the range 0.1 MPa to 6.0 GPa, 1000–2000°C over a wide span of composition. Our model is derived from the Jadeite melting equilibrium, via the relationship ΔGƒ(P,T) = −RTlnKƒ = RTlnD*Na where ΔGƒ(P,T) is the Gibbs free energy of fusion of Jadeite ...

Grapevine rootstocks in K- and Ca-rich volcanic soils: The effect of mineral assemblage on nutrient uptake efficiency

OENO One
This study examines element mobility in volcanic soils to evaluate the relationships between mineral assemblage and the uptake capacity of rootstocks. The Gravesac rootstock, which appears to have a low capacity to selectively absorb K, Ca, Mg, and Na ...

Geochemistry of pillow lavas and their clinopyroxene: ophiolitic mélanges of Nain and Ashin, northeastern Isfahan province

Journal of Economic Geology, 2016
The Nain and Ashin ophiolites are located in northeastern Isfahan province, in western Central-East Iranian Microplate. Pillow lavas are one of the most significant Cretaceous rock units.

Mineralogy and Geochemistry of Ilmenite-Clinopyroxene Symplectite Xenoliths from Vitim Alkaline Basalts and Yakutian Kimberlites (Siberia, Russia) [PDF]

, 2010
application/pdfThe ilmenite-clinopyroxene symplectites are rare among xenoliths from kimberlite and related rocks. We found similar ilmenite-clinopyroxene symplectite nodules in Miocene picrobasalts and Pleistocene basanites of the Vitim volcanic field ...

The clinopyroxenes of the Otaki dolerite sill

The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1962
Three clinopyroxenes, separated from main dolerite and dolerite pegmatites of the Otaki sill (tholeiite series), Yamagata Prefecture, have been chemically analysed and optically determined. These pyroxenes are an augite (Wo36 En41 Fs23) and two subcalcic ferroaugites (Wo26 En36 Fs38 and Wo18 En34 Fs48).
