Outline of Final Research Achievements

Broad-band magnetic susceptibility (MS) measurement, a novel magnetic method capable ofquantifying a narrow grain size distribution (GSD) of superparamagnetic (SP) particles by measuring low-field MS at a number of frequency steps spanning four orders of magnitude, has been developed and tested in a loess/palaeosol section at Luochuan in the Chinese Loess Plateau. The
studied succession consists of sequences from the latest palaeosol unit (S0) to the upper part of the loess unit (L2), spanning the last glacial-interglacial cycle. Results indicate that the mean volume of SP particles in this loess/palaeosol sequence tends to increase during the transition from loess→weak palaeosol→palaeosol, an indication of grain growth as pedogenesis progresses.
