摘要:... The in situ major and trace element compositions of clinopyroxene in co-genetic basalts, andesites, trachyandesites and rhyolites from the Iheya Ridge in the middle Okinawa Trough are examined to determine their petrogenesis and the influence of slab subduction. Regarding the...

摘要:Abstract(#br)We present elemental maps and intra-crystal compositional profiles conducted on a representative clinopyroxene phenocryst from the 1974 eccentric lava flows at Mt. Etna volcano (Sicily, Italy). The eruption was fed by deep-seated and primitive magmas ascending thro...

摘要:... Etna volcano in order to examine the crystallization mechanisms controlling the textural and compositional variability of clinopyroxene. Experiments were performed at 400–800 MPa, 1050–1200 °C, 0–4 wt.% H 2 O and at oxygen fugacity 2 log units above the Ni-NiO + 2 ...

摘要:... Here, we address this issue through a combined geochemical and petrological study of clinopyroxene phenocrysts in intermediate volcanics from the Middle-Lower Yangtze Valley in South China. Clinopyroxene phenocrysts in these volcanics exhibit various types of textural feature...

摘要:Abstract(#br)We investigated the Sr–Nd–Hf–Pb isotope compositions of clinopyroxene separates and strongly leached bulk rock powders from the basalt lavas on Raivavae Island in the South Pacific. These data allowed us to explore the magma chamber processes of the two basal...

摘要:Abstract(#br)To provide new insights into the origin of megacrysts and metasomatism of the subcontinental lithospheric mantle (SCLM), we present a detailed petrographic and geochemical investigation of clinopyroxene-phlogopite xenoliths and clinopyroxene megacrysts from the Grib...

摘要:... As the most common phenocryst in basalt, clinopyroxene with diverse textures and zoning patterns can be classified into 6 types. Type 1 clinopyroxene, occurring throughout the whole basaltic sequence is unzoned or normally zoned. Type 2 to type 6 clinopyroxenes, only observ...

摘要:Abstract(#br)The effects of crystal chemistry and melt composition on the control of clinopyroxene/melt element partitioning (D) during the assimilation of olivine/peridotite by felsic magma have been investigated in Mesozoic high-Mg diorites from North China. The assimilation ...

摘要:... We have examined the in-situ major element, trace element and Sr isotope compositions of the clinopyroxene phenocrysts in these dykes in order to evaluate the extent of magma mixing and source metasomatism. Depending on the type of mineral zoning, the clinopyroxene phenocrys...

摘要:Abstract(#br)We have experimentally confirmed that the solubility of SiO 2 in clinopyroxene at ultrahigh-pressure metamorphic conditions is buffered by coesite and kyanite. The present findings were derived from high-pressure experiments on metapelite glass, powdered andesite...
