Zonal features of Al-Fe-humus pedogenesis on moraine deposits in the Kola Peninsula

Geochemistry and extractable Fe and Al in cold‐temperature soils of northwestern Siberia

“…Total Fe reported here, in the range of 1.1-5.1% (see Table 2), is considerably lower than samples analysed 400 km to the south in the taiga and mixed taiga-forest, where reported concentrations reach $20% (Vasilievskaya et al, 1986) and somewhat similar to within AE10% of reported values in tundra podzols of the Kola Peninsula (Pereverzev, 2007).…”

“…They are among the least understood soils in terms of the degree to which palaeoclimate affected chemical weathering processes. Extractable Fe and Al have been used to classify soils (Blume and Schwertmann, 1969;Lutwick and Dormaar, 1983;Mahaney and Fahey, 1988); to date deposits (Mahaney and Sanmugadas, 1985;Birkeland et al, 1989;Mahaney, 1990;Mahaney et al, 1991Mahaney et al, , 1999; to analyse pedogenesis in tundra podzols (Pereverzev, 2007); and to determine perched water tables (Mahaney and Fahey, 1988). The neutron activation analysis of soils not only provides total concentrations of Fe and Al, but also the concentrations of other major, minor and trace elements that yield important information on profile chemical uniformity and the movement of soluble chemical elements.…”

Lithic Humicryods and Haplocryods: Disjunct alpine–subalpine soils of the Northern Hemisphere

“…Although Lithic Humicryods and Haplocryods occur in lowelevation, temperate rainforests of southeast Alaska, they are especially predominant in alpine-subalpine ecosystems of the northern Appalachian Mountains, the North Cascades of Washington and British Columbia, the northern Rocky Mountains, the interior mountains of Alaska, and elsewhere in the Northern Hemisphere Norway (Ellis and Matthews, 1984;Caseldine and Matthews, 1987;Earl-Goulet et al, 1998), Switzerland (Bouma et al, 1969;Egli et al, 2001), the Carpathian Mountains of eastern Europe (Skiba, 2008), eastern and middle Siberia, Karelia, and the Kola Peninsula in Russia (Mazhitova, 1988;Pereverzev, 2007), and in the Japanese Alps (Shoji et al, 1982). However, the pedons reported by these investigators either were too deep or contained insufficient organic C in the Bhs horizon to be classified as Lithic Humicryods.…”
