Measurements of the partitioning of lithium between clinopyroxene, olivine, plagioclase and hydrous fluid at 800–1100°C and 1GPa indicate this element is mildly incompatible in the solid relative to the fluid phase, similar to mineral–melt systems. Both clinopyroxene- and olivine-fluid partitioning decrease with increasing temperature (T, K) by the relations:lnDLicpx/fluid=−7.3±0.5+7.0±0.7∗1000/TandlnDLiol/fluid=−6±2+6±2∗1000/T...
Seven rock samples were systematically collected from innermost to the outermost portion of a dike outcropping at Mt. Etna volcano. Results show that, from dike core-to-rim, plagioclase, clinopyroxene and titanomagnetite show compositional variations due to increasing cooling rate. Plagioclase is progressively enriched in An from innermost to the outermost part of the dike. Similarly, clinopyroxene...
