...J. Plášil; M. Dušek; J. Čejka; J. Sejkora Abstract The crystal structure of rabejacite from Jáchymov, ideally Ca 2 [(UO 2 ) 4 O 4 (SO 4 ) 2 ](H 2 O) 8 , was solved by charge flipping from single-crystal data and refined to R 1 = 11.94% for 1422 unique observed reflections [ I > 3σ( I...

... Joachimsthal) ore district, Western Bohemia, Czech Republic. It grows on altered surface of relics of primary minerals: uraninite, chalcopyrite, and tennantite, and is associated with pseudojohannite, rabejacite, uranopilite, zippeite, and gypsum. Sejkoraite-(Y) forms crystalline aggregates consisting...
