摘要This research focuses on the geographical distribution and occurrence of freshwater coated
grains on the Hengchun Peninsula. Field surveys showed that coated grains were mainly distributed in
areas with spring water seepage in Siangjiao Bay and the Gongyuan Road Reservoir, and a small amount
has developed at Fongchuisha. Most coated grains were well-rounded with a smooth surface. However,
those which had grown in the catchment sedimentation sink of the Gongyuan Road Reservoir site are
unique. Each has a peculiar outer layer composed of short dense branching protrusions. The results of rock
thin section and electron microscope inspections showed that the formation of these two types of coated
grains is by intermittent rolling and the growth of microorganisms on the top of the grain. Their quite
different appearances may reflect the relative stability of the growth substrates.
