| Abstract: | Size distribution of the purple soil particle is deeply influenced by its purple parent materials.There are suitable rates of sand, silt and clay in red-brown purple soils and grey-brown purple soils.The main clay mineral in the purple soils is illite,that is partly reformed in the soil froming process. Al, Fe accumulation is clearly found in the red-purple soils. |
