A Soil Chronosequence from Neoglacial Moraines in Western Norway
A soil chronosequence is presented based upon podzols developed on Holocene moraine crests in the Jardalen cirque complex, western Norway. Simple and inexpensive field and laboratory tests provide information on soil depth development, pH changes, silt/clay translocation and B-horizon reddening and thickness with age. Chronological control on historical moraine ages is provided by lichenometric dates, which support a 5 cm/100 year soil development rate for the first 700 years of pedogenesis. This initial rapid depth development tails off to a maximum rate of 0.06 cm/100 years between c. 1.5 ka and 10 kaBPbased upon a Preboreal/Younger Dryas age for the oldest moraines and associated soils in the Jardalen cirque.
