Информационная летопись эволюции Аральского моря

Abstract

This study is a fragment of the information chronicle of the evolution of the Aral Sea, captured on the sites of ancient shores and paleorusels, in the discovered archaeological artifacts and traces of ancient structures (settlements) on the exposed bottom of the Kazakh part of the Southern (Big) water area The Aral Sea. It is shown that fluctuations in the water cycle, including migration (meandering) Both the Amudarya and the Syrdarya rivers were an important prerequisite for the emergence of a unique settlement culture in the oasis areas of the arid zone. The analysis of paleorousels reveals that the duration of regressive periods in the evolution of the Aral Sea lasted longer than transgressive processes. Throughout the transgressive-regressive processes, the Syrdarya River had a more or less stable flow with significant migration (change) of the channel, but always with a directional flow into the Aral Sea, while the Amudarya radically changed its course. The studied materials are the most valuable source for a wide range of researchers, as well as the key tounderstanding the large-scale processes of the evolution of the Aral Sea.
