结果显示，紫色沉积岩发育的土壤，在一定程度上继承了母岩的特点，化学风化作用微弱。
The results show that the soils have, in varying degree inherited some properties of purple sedimentary rocks for their very weak chemical weathering.
频率曲线众数峰含量随深度的变化，不但指示了化学风化趋势，而且反映了风化程度的变化梯度。
The variation of frequency curve's mode peak content with the increasing of depth, shows not only the trend of chemical weathering but also variation gradient of weathering extent.
不同风化程度的岩石处于整个化学风化过程的不同阶段，因而具有不同的化学成分和风化度指标。
Rocks with different weathering degrees should possess distinctive chemical compositions, which thus can be used to develop various weathering indices.
