Scientific achievements:

 

In the late 1970 Yurij Vasil’chuk became interested in the isotope composition of ground ices. For the first time in 1982 he yelded detailed isotope diagrams of ice-wedge ice dated by radiocarbon. He has studied from 1975 to 2004 more than 50 representative cross-sections with large ice wedges from Vorkuta up to Uellen. Isotope composition and geochemistry were studied in Holocene and Late Pleistocene ice-wedge ice of Seyaha, Gyda, Matyui Sale complexes on Mammoth Peninsula, Tambey River, Yeryakha River, Lyakkatosyo River, Yaptiksale and Kharasavey site, Yuribey River, Tanama River, Belyi Island, Ngarkatetnedayakha River, Mongatalyangyakha River, Napalkovo, Tadibeyakha River, Northern Yakutia: Bykovsky Peninsula in Lena River mouth, Bison, Zelyony Mys, Duvanny Yar, Plakhinski Yar ice-wedge complex and Alyoshkinskaya terrace in Lower Kolyma River valley, Kular ice-wedge complex; Tyalychima River and Mamontova Gora natural exposure in Central Yakutia, Northern Chukotka: ice-wedge complex on Ayon Island, Lavrentiya, Southern Chukotka, near Anadyr' town, Mayn River Valley - Ledovy Obryv and Ust’-Algan ice-wedge complex; Mountain areas of Magadan Region: Seymchan, Utinoe and Phoenix ice-wedge complex, Myorzlui Yar in Upper Yenisey River valley, Chara River valley in Northern Trans-Baikal region.

He developed isotope geochemistry as applied to cryolithology and palaeogeography. He did pionering and fundamental work in this field. He initiated integration of stable isotope composition of grounf ice into proxy reconstructions. As a result a concept of Late Pleistocene super permafrost zone and the quantitative palaeotemperature script of cryosphere development in Late Pleistocene for northern hemisphere on the base of stable isotope plots of ice wedges and glaciers have been created. Paleoclimatic events recorded in isotope composition of ice-wedge ice were synchronizated and compared with ice core master chronology. He has formulated a new model of cyclically - pulsing formation of large syngenetic ice wedges. It is provided direct chronological comparison of isotope records of ground ices and ice sheets and also reliable age setting for the last 40 ka.

In 1998 he obtained first ¹⁴C dates from ice-wedge ice using AMS ¹⁴C dating of organic microinclusions in the Seyaha Late Pleistocene and Shchuch’ya Holocene cross-sections of Yamal Peninsula, Late Pleistocene Bison, Zelyony Mys, Duvanny Yar, Plakhinski Yar, and Mamontova Gora cross-sections in Yakutia. The AMS dates show that in the ice wedges the older ice is located below the younger. The ¹⁴C dates yield for the first time a timescale (in ¹⁴C years) for paleoclimatic indicators (oxygen and hydrogen ratios from the ice). Also for the first time a pollen extracts from Late Pleistocene ice-wedge ice was dated (together with A.C.Vasil’chuk) in 2002 from Seyaha and Bison cross-section. It has been shown, that due to good safety of ancient pollen and spores the ¹⁴C age of pollen concentrate often is older than the organic micro inclusions.

High-mineralized ice wedges were found at Belyi Island and at Yavai Peninsula. An opportunity of sea waters addition in ice-wedge ice has been shown. Continental type of ice-wedge mineralization caused by salt concentration in lacustrin-marsh waters has been distinguished in Mamontova Gora cross-section.

He has studied geochemical and pollen composition of massive ice in Yuribey River valley and in Kharasavey site, Yamal Peninsula, in Tanama River valley, Gydan Peninsula, near Anadyr’ town and at Koolen’ Lake in the east of Daurkin Peninsula. Different origine of massive ice has been shown.

Detailed radiocarbon dating of palsa in Bol’shezemel’skaya tundra has shown, that the palsa formed in different time intervals, including Holocene optimum.

His hypothesis of mammots’ population decrease and their subsequent extinction shows that the main reason for extinction of mammoth fauna could be sharp changes of winter temperatures at Pleistocene/Holocene transition. Increasing Atlantic influences caused an increase of winter temperatures and the appearance of winter thaws. Resulting multilayered ice crust made it impossible to fine food and to move in the winter. He shows that the southern boundary of mammoths’ distribution is close to the southern limit of the ice-wedge casts distribution and therefore to the southern limit of severe permafrost. He also compared AMS radiocarbon results on amino acid separations with mammoth’s bone collagen from the same specimens treated by HCl and dated by beta counting.

His research interests include the application of isotope geology and geochemistry to isotope and chemical composition of a snow cover and glaciers Bolshoi Azau and Garabashi in Elbrus area, Caucasus, glaciers of Polar Ural, aprons of Khibiny Mountains and Kozel’ski Glacier in Kamchatka Peninsula. Isotope distribution in snow cover of North-east of Europe is studied.

For the first time reseach of enzimatic activity has been applied to snow cover, ice of glaciers, ice-wedge ice, massive ice, and structureforminf ice. It has allowed to determine facial features of ice formation.

Macrocyclic multistage ground veins system was studied and AMS ¹⁴C-dated in archeological site Chongokni (about 50 km northern than Seoul), very important archeological site of Southern Korea. Three important features were distinguished such as: 1) the sediments dated from 13 up to 35 ka BP; 2) ground vein complex has multistage structure caused by cyclic-pulsing character of sedimentation; 3) ground veins formation most likely, is influenced by frozen cracking under more cold winter conditions in Late Pleistocene. The main result of ¹⁴C AMS dating is the Late Pleistocene age of multistage ground veins complex.

He has organized Geocryologic Expedition in Design and Research Institute on Construction in 1983. As a head of Expedition he undertook field investigations in nearly all permafrost regions of Eurasia, such as Gydan and Yamal Peninsulas in the North of Western Siberia, Central and Northern Yakutia, Chukotka, Magadan region, Trans-Baikal region and Arctic Islands. The Program of Interregional Correlation of syngenetic permafrost sediments of Northern Eurasia was fulfilled. He studied features of modern ice-wedge formation. He has done the long-term forecast of exogenic geological processes in the north of Western Siberia within the framework of Global Changes. He studied preservation of the isotope signature in the ice-wedge ice. Palaeogeography and geothechnical maps is a result of his professional activity. Some of them were marked by awards of Geology Ministry of the Russia, Ministry of the Higher Education of the Russia, and Exhibition of National Economy Progress.

He contribute his efforts to the development isotope paleo cryolithology. He taught an ogiginal lecture cource The Principles of isotope cryolithology and glaciology at Geography faculty, Lomonosov’State University. The main feature of this research direction is quantitative palaeotemperature reconstructions of cryosphere and atmosphere for the last  40 ka. This direction is the base for climatic models of new generation, in which direct paleoclimatic indicators and data of mathematical climatic modeling are used  interactively for the study of paleotemperature changes for the last 50 thousand years.
