Description 463-472
A
total of 155 surface sediment samples were collected from the littoral area of
Yellow River Delta in 2007, and analyzed for texture and composition. Using
geostatistic analysis, it is founded that there exist notable spatial
autocorrelation of the

clay
and sand fractions in these samples with the autocorrelation scale being 44 km
and 39 km, respectively. In comparison, the spatial autocorrelation of silt
fraction is moderate, with the autocorrelation scale of 27 km. Analysis also
reveals that the

anisotropy
of the sediment components is clear at the scale 60 km and
the distribution of the depocenters of sand fraction (i.e. content up to 40%)
is very heterogeneous. Boundaries between these sedimentary units and their
substratum

are
very sharp.
