Abstract

Factors affecting rates and degree of soil formation on Holocene moraines are discussed with reference to moraine sequences in the Cirque de Troumouse, French Pyrenees. In particular, the role of time, slope position and post-depositional history are evaluated for three moraines ranging in age from c. 5000 to c. 1000 yr BP. Soil profile development, as determined by visual criteria, indicates differences in soil development between moraines of different age as well as between soils developed on the same moraine but occupying different slope positions. Particle size analysis and soil chemical analyses confirm that microtopography exerts a strong control on the extent and rate of soil formation, and must therefore be considered when sampling and describing soil chronosequences on glacial moraines.
