Holocene soil chronofunctions, Southern Alps, New Zealand

摘要: Abstract Field and laboratory data for two soil chronosequences from the high country of South Island New Zealand suggest rapid formation rates. The areas studied are Ben Ohau Range Mt. Cook area, where mean annual precipitation is about 1 4 m, respectively. Most ages estimated thicknesses rock weathering rinds. Soil chronofunctions derived indices that depict field profile color development, a modified index anisotropy data. Out possible 21 chronofunctions, 16 statistically significant (at 0.05 level) 8 each area. (13) best fit power model, remaining ones split between linear (2) exponential (1) models. Although problems exist in purity because other soil-forming factors not constant, duration pedogenesis seems to be most factor explaining trends. Despite large differences areas, many curves property vs. time quite similar.
