Fig. 2.16. Orientation diagrams for long axes of pebbles in the dump moraine ridge<br />

(fragments 2 on Fig. 2.13) in the Lovozero area. Sites where the measurements were<br />

conducted are shown in Fig. 2.14.<br />

Stop 4. Dump moraine ridge bordered with the push ridge - the inner band of<br />

Revdozerskii marginal belt<br />

Dump moraine ridge bordered with the push ridge (fragment 3 in Fig. 2.13) is located 300<br />

meters south of Stop 3. The inner structure of the ridge was studied in the fresh outcrops<br />

during the mining (Yevzerov, Kolka, 1993). The outcrop is oriented across the ridge strike<br />

(Fig. 2.13, fragment 3). It consist of poorly sorted sand-gravel-pebble sediments with<br />

boulders. Indistinct layering and poorly expressed folds were revealed (Fig. 2.17).<br />

The orientation of the pebbles’ long axes in this part of the dump moraine ridge (Fig. 2.18)<br />

confirms that the clastic material was removed from the glacier in the northeastern direction,<br />

across the ridge strike.<br />
