The new K, Pb-bearing uranyl-oxide mineral kroupaite: Crystal-chemical implications for the structures of uranyl-oxide hydroxy-hydrates
Original language description
Kroupaite (IMA 2017-031), ideally KPb0.5[(UO2)8O4(OH)10].10H2O, is a new uranyl-oxide hydroxylhydrate mineral found underground in the Svornost mine, Jachymov, Czechia. Electron-probe micro-analysis (WDS) provided the empirical formula (K1.28Na0.07)1.35(Pb0.23Cu0.14Ca0.05Bi0.03Co0.02Al0.01)0.48[(UO2)7.90(SO4)0.04O4.04(OH)10.00].10H2O, on the basis of 40 O atoms apfu. Sheets in the crystal structure of kroupaite adopt the fourmarierite anion topology, and therefore kroupaite belongs to the schoepite-family of minerals with related structures differing in the interlayer composition and arrangement, and charge of the sheets. Uptake of dangerous radionuclides (Sr-90 or Cs-135) into the structure of kroupaite and other uranyl-oxide hydroxy-hydrate is evaluated based on crystal-chemical considerations and Voronoi-Dirichlet polyhedra measures. These calculations show the importance of these phases for the safe disposal of nuclear waste.
