Isotope composition (d18O and dD) of buried firn on the Lens and Amga river plain
Layers of firn related to Karga (MIS 3) and Zyryan (MIS 4) horizons of Late Pleistocene were recovered in the permafrost stratum of Central Yakutia. Imaging points of δ¹⁸O and δD values characterizing the firn horizons are grouping near the line of meteoric water (Craig line). The firn was probably...
