MAGNETIC HYSTERESIS PARAMETERS OF BULK SAMPLES AND PARTICLE-SIZE FRACTIONS OF THE LOESS/PALAEOSOL SEQUENCE IN CENTRAL CHINA

Year, pages: 1993, 325 - 333

Measurements of the magnetic hysteresis parameters on bulk samples from different units of the Malan and Lishi Formations of the loess/palaeosol sequence in Potou (Luochuan) and Jiacun (Baoji), confirm the enrichment of magnetites with sizes near the SP/stable SD boundary in the soils. The magnetic properties of particle-size fractions of a sample from S3 and of L4 in Jiacun show a bimodal distribution.They also indicate the large contribution of the clay fraction to the magnetic properties in the palaeosols and hence of the pedogenic contribution. The total amount of hard imperfect antiferromagnetics is more or less the same in both loess and soils, but enriched in the clay fraction of the soils. Their contribution to the magnetic properties is negligeable in the soils, but clearly evidenced in the coarse and silt fraction of the loess.
