Lanthanum and Scandium Distribution in Three Glacial Soils of Western Wisconsin
1969
Kline, J. R. | Foss, J. E. | Brar, S. S.
Neutron activation analysis was used to deterimne the total La and Sc content of three soils developed from loess-capped glacial till. The profiles were classified as Gray-Brown Podzolics (Hapludalfs) overlying paleosols developed in Rockain till. The total La content in the less than 250µ fraction of these soils ranged from 18.1 to 37.1 ppm, with an average content of 23.7 ppm in the loess and 28.5 ppm in the glacial till. Total Sc in the soils ranged from 5.1 to 10.9 ppm with average contents of 6.5 and 9.0 ppm in the loess and glacial till, respectively. Translocation by pedogenic processes was indicated by the accumulation of these elements in the argillic B horizons. Correlation coefficients of La and Sc with clay percentages in the profiles were 0.79 and 0.88, respectively.
