Hypsometric assessment of the pre-last Glaciation (Late
Saalian) topography, the south-east Lithuania
The article deals with the hypsometric assessment of the
pre-last Glaciation (Late Saalian) topography which represents a glaciogenic
landforms of the Medininkai stadial in south-east Lithuania. The study area
belongs to two elevations as orographic units: the Lyda Plateau and the Ašmena
Upland. Cartometric topography analysis has been performed in nine reference
areas based on large-scale (1:25 000) cartographic maps. The topographic
relative height varies from 11.8 m to 30.6 m and depends on the surface altitude
(correlation coefficient R = 0.85). The correlation links between the base and
top surfaces (R = 0.74–0.92), concave-convex graph of hypsometric curves and
value of hypsographic integrals (0.45–0.58) indicate that in general pre-last
Glaciation topography of south-east Lithuania at the present stays in
equilibrium conditions.
