Concentration of heavy metals in the Elk Point evaporite sequence, Saskatchewan.

The vertical distribution of copper, lead, and zinc in the Elk Point evaporite sequence shows a close correlation with the lithology. The highest contents of all three metals are found in the shale, dolomite, and anhydrite of the sequence. Concentrations of heavy metals in the Elk Point evaporite sequence are very high compared to concentrations of the same metals in sea water, by factors of 11 to 826 for copper, 54 to 1130 for zinc and 6000 to 9.02 x 10 5 for lead.
