"Electron microprobe study of mineral chemistry, chemical age and alteration of detrital monazite as well as composition and textural position of authigenic REE minerals - rhabdophane-(Ce), synchysite-(Ce) and thorogummite - have been carried out on the samples of clastic Culm sediments from the Drahany Uplands. Detrital monazite is commonly homogeneous in BSE, only it exceptionally shows an irregular zoning. Some monazite grains are replaced by apatite and hydrated REE-minerals propagating from rim inwards and along fractures. Three different stages of detrital monazite alteration were observed: the first stage is characterized by minor depletion of heavy REE (Gd, Dy, Er), Y, Th and Pb, but it does not show any significant deviations in the ideal stochiometry. The second stage is accompanied by strong depletion of Gd, Dy, Er, Y, Th, U and Pb, the stochiometry is disrupted and totals decrease up to 98-96 wt. percent of oxides."@cs . "\u0160koda, Radek" . .
