Fig. 2.10. Position of marginal moraine ridges in Lovozero area. The stop numbers of Locality 2 are shown by figures in the circles. 24 Stop 2. Marginal ridge north of the Lovozero Mountains The marginal ridge is closed to the north foothills of the Lovozero Mnts. (Fig.2.1-2, 2.10-2). The height of the ridge is up to 15 m, the width at the base reaches 30-40 m. The slopes are steep (up to 35 0 ). The south end of the ridge is cut by the lateral meltwater channels (Fig 2.11). The channels are well-developed on the northern slopes of the Lovozero massif. The ridge is composed of gravelpebble-sandy sediments with a large amount of boulders up to 1,5 m in diameter. The psephitic material is represented mainly by the local crystalline rocks (nepheline syenite), and by the erratics (gneiss-granite). Fig.2.11. Marginal meltwater channel cutting the ridge near the foothill of the Lovozero Mnts.
There are two opinions on the genesis of this marginal ridge: 1. This marginal esker marks the position of the glacier edge during the interstadial warming. It could be compared to the inner band of the Revdozerskii marginal belt (?). As the ridge is cut by the washout meltwater channels, traceable here and on the mountain slopes, the esker formed before the glacier has moved to the east and climbed to the mountains along the river valleys. 2. This ridge is the marginal form of the local (mountain) glacier, moving from the Raslak Cirques (Yevzerov et al., 2007) (Fig.2.12.). The material composing the ridge is predominated by nepheline syenite of the Lovozero nepheline syenite pluton (from 64 up to 98 %) while the ridge being located outside the contact of Lovozero nepheline syenite pluton. Fig. 2.12. Position of the submountain glacial deposits and petrographic composition of their pebble fraction. 1 - ridges of marginal and medial moraines of submountain glacier, 2 - contact of the Lovozero massif, 3 - content of pebbles in the nepheline syenites of the Lovozero massif, 4 - content of pebbles in the acid and basic rocks of the basement. Stop 3. Dump moraine ridge - the inner band of Revdozerskii marginal belt. The marginal moraine complex is situated north-east of the settlement of Revda, in the area of the north-eastern extremity of Lake Revdozero, south of the road Olensgorsk- Lovozero(fig.2.1-3). The marginal complex has a complicated structure. It is represented bу а locally developed dump moraine ridge extending from the north-west to the south-east in the form of five fragments, and a small glaciofluvial delta (Fig. 2.13). Stop 3 is located in the former open-pit, outcropping the fragment 2. Some fragments of the dump moraine ridge (fragments 3 and 5 on Fig. 2.13) borders on the push ridge in the west. The fragments of the dump moraine ridge (Fig. 2.14) are up to 15-20 m high above the foot and up to 0,6 km long. Near the distal (eastern) side, a terrace-like bench takes place, likely formed by the flowage of the debris from the glacier takes plase. 25
