Clay (< 0.001 mm) and coarse clay (0.001-0.005 mm) fractions consist of illite, kaolinite, vermiculite, chlorite, chloritized vermiculite and quartz. Vermiculite content increases in the upper horizon whereas illite content decreases. Chloritization of 2:1-silicates takes place especially in the B horizon. It is difficult to recognize some clay minerals or some features of their distribution in the profile specific for the whole type of brown forest soils. The formation of chloritized vermiculite seems to be specific for most acid brown forest soils.
