Composition and morphology of the ridge with push moraine basement at the Moseevo village (western part of the Terskie Keivy, the Kola peninsula)

Composition, genesis, morphology and age of the end moraine formations are topical problems in Quaternary geology of the Kola region. During the field works in summer 2017, the ridge, included in internal part of the end moraine belt of Western Terskie Keivy, was investigated. Morphological features of the ridge were identified. There are asymmetrical slopes, flat summit, roll-shaped topography on the eastern slope. Composition of the ridge was studied in 3 natural outcrops and 3 open test pits. Geological, structural and geomorphological methods were used. The studied ridge is composed of glacial (ablation and lodgement tills) and fluvioglacial deposits, with folded till in its core. Structural features of the glacial units testified to that the glacier moved from south-west to north-east. Forming stages of the ridge, its coinciding with marginal zone and dynamic peculiarity of the Belomorskii Lobe of the Last Glaciation was recognized according to the geological structure and surface morphology of the studied ridge.
