Figure 6

(a) Lithological log showing key units and dominant grain size. Colours used to distinguish units and are representative, (b) AMS 14C ages, (c) sedimentary structures, (d) lithofacies, (e) shear strength data (blue), grain abundance >2 mm per 10 cm3 (black dots), (f) grain size percentages, and (g) the Illite/Chlorite ratio in the clay (<2 μm fraction). (h,i) X-radiographs showing massive structure of the gravel-rich units. Black bar in ‘h’ shows location of sample for dating, red line shows boundary between units (j) core photograph of a section of the lowermost ‘moraine unit’ (lithological Unit I) illustrating large angular clasts in homogenous matrix. Legend relates to panels a–d only.
