The distribution of rare earth elements and yttrium in gadolinites from deposits of four different genetic types was studied by x-ray spectral analysis. It is shown that the character of the distribution of elements in gadolinites (belonging to the number of so called complex minerals) strongly depends on the conditions of formation. The most enriched in yttrium are the gadolinites, the formation of which is connected with granitic and alkaline pegmatites. The richest in cerium are the accessory gadolinites. If albitization processes are developing in gadolinites, an accumulation of yttnium and ceric rare earth elements and a removal of yttric earths occur. (anth)
