Abstract
The concentrations of Au, Ce, Cr, Eu, Hf, La, Lu, Sc, Sm, Th, U and Yb were determined by instrumental neutron activation analysis in 1200 samples of glacial till from Quebec by using a SLOWPOKE reactor. All these elements are lognormally distributed in the till which would suggest that their concentrations, while reflecting somewhat the composition of the bedrock, are apparently not regulated about a central value by any geological process.
