Це стосується і добре виражених форм, насаджених на підняття корінних порід. Схарактеризовано особливості седиментаційних процесів при формуванні презентованого каму (акумуляція матеріалу в межах дрібного басейну накопичення). Наголошено на специфічних умовах формування камів в околицях м. Ковель та значну роль особливостей льодовикового ложа.Kames are widespread in the basin of Middle Turia. Here among the kames you can distinguish large dome- or plateauforms, placed on elevation of bedrocks. However, they are not sufficiently studied. It concerns both their morphological features, nature of correlation with irregularities of the glacial bed, correlation with surrounding glacial forms, and geological structure of these accumulations. Examples of such forms are the Kames, located along the left side of the valley of the river Turia near the city of Kovel. Their morphology and geological structure indicates the specific conditions for the formation of a complex of these forms. In this work we have analyzed morphology and geological structures of the form, located east of Liublynets of Kovel district (Volyn Polissya), and we tried to explain the conditions of its formation. During the research we used morphological and morphometric methods, as well as the method of lithofacies analysis. The geological structure of the form was studied in the north-eastern part of the chalkpit, located in the eastern outskirts of the village, where the sand is extracted for construction needs. The conducted researches have established that there are three lithofacies complexes in the form structure reflecting various conditions of sedimentation. The gravel and gravelly coarse-grained sands, gathered in series with large trough cross-stratification, are the basis of the form, which represent the channel settings. Above the cut they are switched by series of multi-grain sands with large trough cross-stratification, which are transfixed with series of sand with horizontal stratification. Among them there are series of unsorted (diamectic) sediments of ablative moraines. These deposits are interpreted as deposits of a small outwash fan of melt water. The form cut is finished with a powerful up to 5 m pack of glaciolacustrine deposits. In the lower parts they consist of layers of loam with sandy loam and fine grained sand. They have a thin horizontal stratification, occasionally massive or intensely deformed. The upper parts of the section of the complex are composed of more sandy lithofacies units with a clearly expressed rhythmic layering character. The most determining factors in forming of the studied form are considered to be the features of the surface and geological structure of the bed, in particular, the elongated separate elevations of bedrocks along the left bank of Turia. They caused the areas of significant tension in the ice that brought to the emergence of cracks over them as the focal points for accumulation of kame sediments. The nature of the deposits of the form indicates that their sedimentation was carried out mainly in stagnant and slightly flowing conditions of lake basins, that changed the fluvial conditions, which at the initial stages of the kame formation had a proximal character (gravel and sand gravel mechanical composition of the lower part of the strata of glaciofluvial deposits) and the situation of the small outwash fan (sandy deposits of the upper part of the strata of glaciofluvial sediments). The glaciolacustrine deposits have signs of significant fluctuations in the level of lake basins (changes in the granulometric composition of clay sediments), which indicates a close hydraulic relationship between the glaciolacustrine and drainage channels leading to the excess of water from it and that was activated from time to time as a result of the strengthening of ablation processes and the degradation of the ice sheet. This led to a significant drainage of the natural lake at the final stages of its functioning and the accumulation of shallow sandy-clay and clay-sandy sediments. The calm character of sedimentation, mainly the fine-grained nature of the deposits and paleogeographical characteristics of the ice mass state allows us to characterize the presented form as a longitudinal glacioelevation kame relative to the glaciofluvial streams with a complex layout of the litofacies complexes.ukгляціоелеваційний камлітофаціальний аналізседиментаціяВолинське Поліссяводно- та озерно-льодовикові осадиVolyn Polissyakamelithofacies analysissedimentationglaciofluvial and glaciolacustrine depositsСтаття
