Abstract

A series of unconsolidated Pleistocene sediments displays décollement folds and faults on a small scale. Correlation between directions of ice movement inferred from till fabrics and the spatial arrangement and shear sense of folds in underlying lake clays indicates that deformation was induced by overriding glacier ice. Fold axes produced by this single deformative event are seen in many orientations relative to the direction of movement of the glacier; some axes are essentially parallel to direction of the glacier movement.
