Late Pliocene-Pleistocene changes in mass accumulation rates
of eolian deposits on the central Chinese Loess Plateau.
Journal of Geophysical Research, Vol. 110, D23101, doi:10.1029/2005JD006064.
ABSTRACT:
Late Pliocene-Pleistocene changes in the mass accumulation rates (MARs) of
eolian deposits on the central Chinese Loess Plateau (CLP) are reconstructed
from measured bulk sediment densities combined with sedimentation rates
calculated for two loess/red clay sequences. The reconstructed MARs demonstrate
that over the past 3600 kyr, distinct aridity-humidity fluctuations occurred
over glacial-interglacial timescales, and these were superimposed on a gradual
long-term drying trend. Comparisons of the CLP MAR record with the MAR and d18O
records for marine sediments suggest that the development of Northern Hemisphere
ice sheets since the late Pliocene has played a part in increasing the aridity
of central Asia. In addition, the phased uplift of the Himalaya-Tibetan Plateau
evidently had a profound influence on the aridity of central Asia; this was
mediated by variations in the East Asian monsoonal circulation. Correlations
among dust records from ice cores, marine sediments, and terrestrial loess over
the last several glacial cycles provide compelling evidence that glacial periods
are characterized by higher and more variable dust fluxes than interglacial
intervals. Synchronous changes in the MAR, grain size, and d18O records reveal
dynamic linkages between Asian interior aridity, paleowind intensity, and ice
volume after the onset of major Northern Hemisphere glaciations.

DESCRIPTION:
Chinese Loess Plateau (CLP) mass accumulation rate (MAR) record spanning
the late Pliocene and Pleistocene, generated from bulk density measurements
on two continuous loess and red clay sequences in the central CLP.
Sedimentation rate for eolian sequences calculated using a refined
astronomical timescale and bulk density measurements.
