[1] Trace elements and stable isotope diagrams of late pleistocene ice wedges of batagaika yedoma, central yakutia / Y. K. Vasil'chuk, J. Y. Vasil'chuk, N. A. Budantseva, A. C. Vasil'chuk // 5th European Conference on Permafrost (EUCOP 2018), Chamonix-Mont Blanc, France, 23th June - 1st July 2018. — Vol. 1. — Deline P., Bodin X. and Ravanel L. (Eds.) (2018): 5 th European Conference On Permafrost – Book of Abstracts, 23 June - 1 July 2018 Chamonix, France, 2018. — P. 132–133. The subject of the study is the yedoma ice complex, which locates in the Batagaika depression, Sakha Republic, Russia. The oxygen and hydrogen stable isotope composition, and the content of the dissolved forms of minor and major elements were studied for the first time in ice-wedges of Batagaika depression, which determines the novelty of the study. The isotope composition of the two most saline ice-wedges located in the upper and lower parts of the Batagay depression indicates that they were formed in a close temperature range, the average winter temperature was close to -34, -35 oC, and the average January air temperature was -51, - 53 oC. The ice-wedge with the lowest content of all the trace elements was formed in more severe conditions, the average winter air temperature was close to -36 oC, and the average January air temperature was -54, -55 oC.
