The paper discusses current mineralization in the small closed lake Skalistoe, located in the territory of Olkhon region (western Baikal area), characterized by the semiarid climate. To analyze the mineral phases formed on unattached algal-bacterial formations (the atmosphere-water interface), submerged algae and macrophytes (water-bottom sediment), and bottom sediments, we used the methods of X-ray diffraction, infrared spectroscopy, and electron microscopy. It was found out that the minerals deposited during the...

In this work the received analytical material on bottom sediments more than 200 lakes is generalized in different landscape (climatic) zones of Western Siberia. The bottom sediments were studied by a set of modern methods of geochemistry, mineralogy, and crystal chemistry. We will try to highlight some of the general laws of horizontal and vertical distribution of natural radionuclides (NRN) in different types of bottom sediments of the inland lakes of Siberia. Based on NRN distribution in the bottom sediment of t...
