δ¹⁸O in ice wedges, ice lenses and snow from Kular, Yakutia (Russia)

Variations of δ¹⁸О in Late Pleistocene ice wedges, in structure-forming ice and segregated ice lenses, as well as in snow and water of Burguat River were determined. The studied section of the yedoma strata has been exposed in an outcrop of the slope sediments on a gentle slope in the foothills of Kular Ridge, nearby Kular Settlement, on the right bank of the Burguat River, 0.5 kilometers from the mouth of the Emis Creek.

本研究测定了晚更新世（Late Pleistocene）冰楔（ice wedges）、构造型冰（structure-forming ice）与分凝冰透镜体（segregated ice lenses），以及布尔古阿特河（Burguat River）积雪与水体中的氧同位素δ¹⁸О变化特征。本次研究的育德玛（yedoma）地层剖面，暴露于库拉岭（Kular Ridge）山麓缓坡的边坡沉积物露头处；该露头位于布尔古阿特河右岸，距埃米斯溪（Emis Creek）入河口0.5千米处，紧邻库拉居民点（Kular Settlement）。
