The relationship between the colloidal surface properties and association of clay mineral, especially 14×10^-10m mineral and clay oxides in 26 horizons of 9 profiles of the yellow brown, soil. red earth and latosol derived from granite type parent material was studied. Results indisated that: 1) The canon exchange capacity, rotal surface area and the proportion of internal surface area decline of 2:1 type clay minerals, 14×10^-10m mineral and the increase of 1:1 type clay minerals and clay oxides. This is also in correspondence with 14×10^-10m mineral being vermiculite in yellow brown soil and 14×10^-10m mineral being 14×10^-10m intergrade mineral in red soil. 2) For two soils with a similar conent and type to other clay minerals; as the 14×10^-10m mineral is vermiculite, the ration exchange capacity, total surface area and the proportion off internal surface area off soil clay is higher, but the active acidity of soil is weaker, the content of exchangeable A1 is lower, whereas the 14×10^-10m mineral is 14×10^-10m intergrade mineral, the situation of these properties is quite oppositive.
