Uranopilit a jáchymovit z uranového ložiska Horní Slavkov

Uranopilite from Horní Slavkov (Czech Republic) forms yellow crystalline aggregates of thick tabular crystals up to 0.5 mm. The aggregates seem to be a part of massive assemblages of uranyl supergene phases, so called „gummite”. Uranopilite is triclinic, with the space group P-1. The unit cell…

Křemen-turmalínová žíla s apatitem-(CaF) z Babic u Šternberka

Hydrothermal veins composed of quartz, calcite and tourmaline of schorl-dravite series are known from many localities in the Šternberk-Horní Benešov Belt, Vrbno Group and Konice-Mladeč Belt in the NE part of the Bohemian Massif. The veins are interpreted to have formed from fluids related to…
