SOME PROBLEMS ON LANDFORM AND QUATERNARY GEOLOGY IN THE REGION OF THE MIDDLE REACHES OF THE FU HE

The neotectonic movement in this area possesses clear characteristics of inheritance, which shows the differential rising of fault block, and. results in the staggering of the peneplain in old Tertiary, which reselve into two steps of planation surface. The rising of fault block bears tilted characteristic, which make the river valley develope asymmetrically, and the same steps planation surfaces are oblique. Vermicular red soil in scuth China is a kind of paleosoil in Quaternary, and can be regarded as a kind of rock-stratigraphy unit, which there are great difference between time and original genesis.
