... milling and the Cu peaks are due to secondary fluorescence from the copper grid that supports the foil. Cpx = clinopyroxene, Chr = chromite. (Color online.) Also observed are euhedral orthopyroxene inclusions (5–20 µm diameter) that exhibit octahedral habits ( Figs. 5a – 5c ). Other small subhedral...

... of olivine microphenocrysts and pheno crysts is ~10 vol.%. Augite occurs as microphenocrysts, ~100–500 μm in size, showing short prismatic euhedral or subhedral habits in thin section, and also occurs as phenocrysts, up to 2.4 mm in size. Augite microphenocrysts and phenocrysts account for ~6 vol.%. Some...

... and albite ( Fig. 1 ). As it is always veined and/or occurs on the edges of other zirconium silicates, the crystallisation of calcioancylite-(La) may be related to the late carbonation. Calcioancylite-(La) forms aggregates of subhedral grains with pseudo-octahedral dipyramidal crystal habit {111} with {110...
