Weathering Regimes and Pedogenic Variability on Large Boulders, Karkevagge, Northern Scandinavia
252 p. Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2001. The following conclusions were established from field, laboratory, and statistical analyses: (1) Clay content was marginally greater in soils developed on garnet-mica-schist than mica-schist; (2) Silt and clay content did not r...
