A MULTIPLE TILL SEQUENCE NEAR ELLON, GRAMPIAN REGION - JAMIESON,T.F. INDIGO BOULDER CLAY REEXAMINED

Jamieson in 1906 described an 'indigo boulder clay' lying beneath youn ger glacial deposits in the Ellon area, Grampian Region. A pitting sur vey has revealed that this unit (the Pitlurg Till) lies beneath Late D evensian glacial and glacifluvial deposits (the Hatton Till and the Ki ppet Hills Gravels and Sands) and rests on a basal till (the Bellscamp hie Till). The Pitlurg Till contains palynomorphs of Kimmeridge Clay a ge and shows weak northerly fabrics, suggesting ice transport from the Moray Firth. Amino acid ratios for sparse included shells indicate th at the Pitlurg Till is younger than Oxygen Isotope Stage 7 and may pos t-date Stage 5e. The Bellscaphie Till lies beneath weathered gravels a t Tillybrex and probably predates Stage 5.
