摘要
本文新构造运动具有明显的继承特点:表现为差异性的断块隆起,由此导致老第三纪形成的准平原发生错位,分解为二级夷平面。断块隆起还具有掀斜性质,造成河谷发育不对称,同级夷平面倾斜。华南的网纹红土是第四纪的一种古土壤,可以列为更新统的一种岩性地层单位,但是它的时代与原始成因的红土,有比较大的变化。
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.
