The content of rare-earth elements of the cerium subgroup in clays from cavities in the productive veins of the Sherlovaya Mountain deposit is studied. Anomalously high contents of silver, zinc, lead, arsenic, tungsten, fluorine, as well as rare earths of the cerium subgroup were found in the clays. The content of rare-earth elements in clays is in the range (ppm): Ce — 0,1...310,0; Pr — 0,05...42,80; Nd — 0,1...162,0; La — 12,1... 141,0; Sm — 0,1...51,8; Eu — 0,7...2,1. Coefficients of their concentration range from 4 to 27. In the loose material containing clays, the presence of bismuthin, bismutliite, ferberite, beryl, monacite of scorodite, and roosevelt- ite has been found. Clays consist of hydroxides of iron, kaolinite, illite-smectite. Chemical analysis has revealed Fe203 (10...25 %), Si02 (18...42 %), A1203 (15,2...30 %), H20 (14,3...17,8 %). Clays of loose material are washed with distilled water. It has been established that the washing water, along with other chemical elements, contains rare earths. Limits content of elements of the cerium subgroup in the washing water are (ppb): Ce <0,01...0,73; Pr: 0,02...0,28; Nd: 0,14...0,813; La <0,01...2,9; Sm <0,01 ...0,14; Eu <0,01 ...0,02. They exceed dark for river water. This indicates a possible broad migration in the landscape and indicates a possibility of concentrating on geochemical barriers in the form of fluorocarbonates |
