Онтогенез лимносистем в ледниковом комплексе рельефа Беларуси

Abstract

Lake hollows are the key feature of glacial relief complex. The article proves that evolution of lakes hollows in Belarus is irrevocable and submits to climate change throughout all the Holocene. Consequently the main reason for sedimentation become selective drain processes: there are always some invariants. Lake sedimentation fixes transformation of substance and energy streams. Existence of lakes in Belarus all this period was possible because of plasticity of sedimentation. The article considers two scenarios of lakes lithocomplex buildup and their geographical binding. They describe the sedimentation background. As a result synchronic and diachronic approaches exhibit a sedimentary rhythm. Main through that intensity of its phases change is an inverse function of substance transformation. Therefore lakes possess sufficient stability if they don’t only accumulate autigeneous silts but also are lying near upper courses of reservoirs with typical zone biomes.
