| Abstract: | To simulate the behavior of As and S in the formation of till, the contents of these elements were determined in the total material, the −0.064 mm fraction and the 0.064–0.5 mm fraction of crushed rock samples. For most of the studied rock types there was a conspicious enrichment of As and a much less prominent enrichment of S in the finest fraction. Accordingly, in the formation of till the mere mechanical crushing of rock material can create enrichment of the derived till. |
