Th e distribution of allotigenic elements (AE) (Li, B, Ga, Sc, Ni, Cr, Co, V, Rb) and allotigenic accessory elements (AAE) (Y, Yb, La, Ti, Zr, Nb) in sandy, sandy loamy or loamy-clayey soil of five glaciolacustrine basins was studied to recognise diff erences in total contents of these trace elements mainly as a result of the different duration of weathering and composition of parent material. Weathering in the Simnas–Balbieriškis basin of the South Lithuanian phase was the longest, in the Venta, Jūra–Šešupė and Kaunas–Kaišiadorys basins of the Middle Lithuanian phase was shorter, and in the Mūša basin of the North Lithuanian phase the shortest. The difference in the duration of weathering is well reflected in sandy soil; it explains most of the significant differences in the content of trace elements and indicates the tendency of a decrease of most AEs and an increase of most AAEs with soil age, while sandy loamy or loamy-clayey soils do not show any significant dependence on weathering duration; the tendencies of variation of most AEs as soil age increases, are opposite compared to sandy soil, and the variation of the contents of AAEs is less expressed, except an increase of Nb. This is predetermined by a more difficult infiltration through these types of soil. Most of the significant differences in AE contents in sandy loamy or loamy-clayey soil of different basins can be explained by the lithological influence of the prevailing type of surface glaciolacustrine sediments (clay or coarser sediments) and the mineralogical influence of the main minerals of surface glaciolacustrine clay (illite and kaolinite), which depend on the material brought by different glacier lobes.
