Summary:A systematic till sampling programme was undertaken to quantify regional variations in drift composition, in order to provide baseline data that might be used in assessing the effects of acid rain. The distribution of: 1) texture and carbonate content of tills and 2) concentrations of naturally occurring trace and minor elements in tills were mapped. Tills in the area are fine-grained, averaging 41% sand, 35% silt and 24% clay. The carbonate minerals appear to have leached to depths >1.5 m. Sites with anomalous concentrations of various trace elements correspond, on a regional scale, with major lithological units in the underlying bedrock. [T.F.]

The distribution of: 1) texture and carbonate content of tills and 2) concentrations of naturally occurring trace and minor elements in tills were mapped. Tills in the area are fine-grained, averaging 41% sand, 35% silt and 24% clay. The carbonate minerals appear to have leached to depths #GT1.5 m. Sites with anomalous concentrations of various trace elements correspond, on a regional scale, with major lithological units in the underlying bedrock.
