The dump ridge is built up of poorly sorted sand-gravel-pebble sediments with boulders. Fresh outcrops display laering.) (Fig. 2.15;) (Yevzerov, Kolka, 1993). Layers that contain abundant pebbles and boulders and dip to NE, E and SE, are interbedded with layers of coarse poorly sorted sand and pebble. Locally, in the section parts oriented across the ridge morphological axis, there are poorly developed folds. 26 Fig. 2.13. Structure of the marginal complex in Lovozero area. Legend: 1 - fragments of dump marginal ridge (1-5); 2 – dump moraine ridge bordered with the push ridge; 3 – hummocky moraines; 4 - esker; 5 - glaciofluvial delta; 6 - sandur; 7 - till plain, 8 – peat-bog glaciodepression; 9 – glaciodepression with cover moraine; 10 - crystalline rock outcrop; 11 - location of the studied sections.
Fig. 2.14. Fragment of the dump moraine ridge in Lovozero area, the view from the distal side. The sediments are poorly sorted, and this feature indicates that the clastic material slipped down the ice slope and was insignificantly redeposited by water. The orientation of the pebbles’ long axes along the ridge’s morphological axis is observed; the longer axis dips in proximal direction (Fig. 2.16). Such orientation of pebbles indicate that the sediments were pushed by the glacier. Fig. 2.15. Section of the dump moraine ridge (fragments 2 on Fig. 2.13) in the Lovozero area. Legend: 1 - boulders; 2 - pebbles; 3 - gravel; 4 - sand; 5 - sites where orientations of pebbles were measured. 27
