CHISTYAKOVAITE, A NEW MINERAL AL(UO2)2(ASO 4)2(F,OH) · 6.5H2O

Abstract

New mineral, hydrous aluminum uranylarsenate, was found during detailed study of uranium mineral samples taken at the Bota-Burum deposit (southern Kazakhstan) by E.V. Kopchenova in the 1950s and stored at the Mineralogical Museum of the All-Russia Research Institute of Mineral Resources (VIMS). The mineral was termed chistyakovaite after the name of N. I. Chistyakova, a senior assistant at the VIMS and well-known specialist in the field of X-ray spectral analysis, who carried out a great number of microprobe analyses of uranium minerals. Chistyakovaite is the second (after arsenoshpathite) aluminum uranylarsenate found in nature.
