BS>A metasomatic deposit 320 m long and 10 m deep showed a high average content of Nb, Ta, Zr, TR (rare earths), U, Th, and Be(1.5 to 2.0 orders higher than the Clark number). The average composition of the lanthanides (with SIGMA Ln = 100%) was as follows: La/sub 4.5/, Ce/sub 18.0/, Pr/sub 3.0/, Nd/sub /8.6/, Sm /sub 4.6/, Eu/sub 0.5/, Gd/sub 6.0/, Tb/sub 1.5/, Ho/sub 4.2/, Er/sub 13.0/, Tu/sub 1.9/, Yb/sub 16.3/, Lu/sub 2.5/. The yttrium cortent on the average was about 2/3 and the SIGMA Ln was 1/3 of the SIGMA TR/sub 2/O/sub 3/ (rare earth oxides). Correlation coefficients are given for the contents of even and odd, neighboring, rare earths. The results on 45 samples show that the lanthanides can be separated into the following correlated groups: 1) SIGMA Ce = La + Ce + Pr + Nd (+Sm + Eu); 2) SIGMA Gd = (Eu +) Gd; and 3) SIGMA Er = Lu + Yb + Tu + Er (+ Ho + Dy + Tb).
