Hydrogen and oxygen isotopes and the origin of the ice in peat plateaus
Abstract δ 18 O and δD values (% SMOW) were measured on 159 samples from the active layer and permafrost on peat plateaus and from the adjacent fen at sites about 50 km north of Tuchitua along the Robert Campbell Highway in southeastern Yukon Territory. The regression lines for the samples from the...
