| Summary: | The study on the shores of the Russian Arctic is a topical scientific and practical problem because the coastal zone is a highly dynamic natural system, the features of which are determined by the interaction of water and land in permafrost. The aim is to study the facial characteristics of Quaternary sediments on the basis of the Yenisei Gulf grain size and mineralogical composition, and studying the characteristics and dynamics of the coast. To meet these goals, tasks were set, including the study of grain size and mineralogical composition of sediments, to study the dynamics of sea coast on the Gulf of key areas, a description of the characteristic facies zones. In this paper we explore the quaternary sediments and the dynamics of the coast of Yenisei Gulf. Quaternary sediments are the main tool for paleoreconstruction. With the help of these studies it is possible to track the trend of climate change in the region, as well as hydrodynamic conditions in the past. The paper uses the data from the 2008 expedition. The presented scheme describes the outcrop, lithology, grain size and mineralogical analyses data. There is also a map showing zones of accumulation, erosion and stable shores. We have also calculated the speed of retreat and leaching of heavy fractions in the Bay. |
