Figure S1. (A) Grain-size distributions of the matrix of different till layers (<2 mm). (B) Clast fabric plotted on a ternary diagram compared with data from other sites (in Benn, 1994). (C) Plot of S1/S3 eigenvalues for the Ballyhorsey clast fabric data, compared with data from other sites (Menzies & Shilts, 2002). (D) Schmidt equal-area projections of clast fabric data of the three different till layers observed at the base of the pit.
Figure S2. Interpreted section 3. Photograph showing the erosive contact between the clay-rich diamicton (F1.1) and the massive and poorly sorted gravel (F3.1). Note the occurrence of clastic dykes sourced in F1.1 that propagates upwards.
Figure S3. Interpreted section 4. Distal part of the wedge displaying mainly sandy deposits (F3.6) that are affected by intense deformation. The deformed zone is characterized by a 3 m wide depression bordered by step normal faults. This depression is surrounded by intense deformation structures including thrust faults (A), asymmetrical folds (B) and clastic dykes (C).
Figure S4. Sedimentary logs 6 and 12. See Fig. 2 for their localizations.
