0RN-4K5Xenotime-(Y) : YPO4, Zircon : Zr(SiO4), Cheralite : CaTh(PO4)2, Quartz : SiO2

Blocherleitengraben, Miesling valley, Spitz, Wachau, Lower Austria, Austria

Xenotime-(Y) (bright grey) as dendritic aggregates within zircon (grey, porous). A different zircon generation (containing Y, P and other impurity elements), formed as an overgrowth is visible in the lower left (bright grey, similar to the xenotime). Small white grains on the right are all cheralite crystallites. Dark area on upper right is an unidentified Fe-Al-Si-O phase (layer silicate?). Matrix is quartz.
SEM micrograph (BSE mode).

9EL-G8XWhewellite : CaC2O4·H2O, Baryte : BaSO4, Calcite : CaCO3

Eichenberg, Pfänder massif, Bregenz, Vorarlberg, Austria

Field of View: 6.2 mm

Whitish, slightly etched, blocky whewellite crystal (centre; damaged by cutting the void open with a saw; SXRD-analysed) next to a colourless, thick tabular baryte crystal (also SXRD-analysed), both grown on drusy calcite coating the void of an "Eichenberger Kugel".
