Аннотация: We estimated the age and sedimentation rate of bottom sediments in Cheko Lake located in southern Evenkia, in the territory of Tunguska Nature Reserve, near the supposed epicenter of the so-called 1908 Tunguska Event. The vertical distributions of Cs-137 and Pb-210 activity and visually counted varves in the core of lake bottom sediments indicate that Cheko Lake is significantly older than the 1908 Tunguska Event; therefore, the lake basin cannot be a crater or a trace of the explosion as was supposed earlier by some researchers.

Geochemical Features of Annual Layers of Bottom Sediments of Freshwater Lakes, Studied via Synchrotron Radiation–Induced XRF Microanalysis / A. V. Darin [et al.] // Bull. Russ. Acad. Sci. Phys. - 2019. - Vol. 83, Is. 11. - P1437-1440, DOI 10.3103/S106287381911008X . - ISSN 1062-8738

Аннотация: Abstract: The possibility of distinguishing layer boundaries through lithological and geochemical indicators (Rb/Sr ratio) is shown by a case study of bottom sediments from Lake Kucherlinskoe (Altai). Based on the data from scanning synchrotron radiation–induced XRF microanalysis and isotope studies, a record of the Tunguska event of 1908 is found in the bottom sediments of Lake Zapovednoye, forty kilometers from the explosion’s epicenter. An anomalous layer in the sediments is associated with an increase in the terrigenous drift in the catchment area due to massive forest outfall and subsequent fires. The possibility of a targeted search for microparticles of extraterrestrial origin in lake sediments is demonstrated. © 2019, Allerton Press, Inc.

Traces of the Tunguska Event (1908) in Sediments of Zapovednoe Lake Based on SR–XRF Data / A. V. Darin, D. Y. Rogozin, A. V. Meydus [et al.] // Dokl. Earth Sci. - 2020. - Vol. 492, Is. 2. - P442-445, DOI 10.1134/S1028334X20060045 . - ISSN 1028-334X

Аннотация: Abstract: An anomalous layer enriched with chemical elements indicating the presence of terrigenous matter was discovered in the sediment core of Zapovednoe Lake located 60 km from the epicenter of the Tunguska event (1908) using synchrotron radiation X-ray fluorescence spectroscopy (SR–XRF). Radioisotope measurements indicate that the age of the layer is consistent with the date of the catastrophe. Apparently, the anomalous layer was formed as a result of an intense terrigenous matter inflow from the water catchment area due to massive forest falls and subsequent wildfires caused by the Tunguska event. Thus, it is established that targeted searches for microparticles of extraterrestrial origin can be carried out in the discovered and dated anomalous bottom sediment layer. © 2020, Pleiades Publishing, Ltd.

Structural Features of Scales of Baikal Grayling Thymallus baicalensis under Conditions of an Altered Hydrological Regime / I. V. Zuev, P. Y. Andrushchenko, S. M. Chuprov, T. A. Zotina // Inland Water Biol. - 2021. - Vol. 14, Is. 1. - P60-66, DOI 10.1134/S1995082920060176 . - ISSN 1995-0829

Аннотация: Abstract: The number of circuli between annual scale rings of grayling Thymallus baicalensis Dybowski, 1874 sampled in the Yenisei River in the downstream section of the Krasnoyarsk Hydroelectric Power Station, which does not freeze in winter, have been investigated and compared with populations of grayling from large tributaries of the Yenisei River (Amyl, Kan, Nizhnyaya Tunguska, and Bolshaya Kheta). It has been shown that graylings inhabiting the Yenisei River have a significantly higher (1.5–2.0 times, p < 0.01) number of circuli in the second, third, and fourth annual rings of the scales than in the populations from the tributaries, which corresponds to a higher growth rate of the grayling population in the Yenisei River. An assumption is made about the transition of graylings inhabiting the Yenisei River channel in the lower reaches of the hydroelectric station to a sedentary lifestyle. © 2021, Pleiades Publishing, Ltd.
