THE MICROMORPHOLOGICAL CHARACTERISTICS OF VARIEGATED HORIZON IN QUATERNARY RED CLAY

The micromorphological charateristics of variegated horizon in profiles of Quaternaryred clay were studied and reported in this paper.The results were as follows:Invariegated horizon,the skeleton grain,with porphritic distribution,was dominated byquartz;the soil body had typical prismatic structure for high development of macro-fissure,the soil matrix was composed of three types which varied in micromorpholo-gical feature and were in the course of dynamic equilibrium;and ferran could becommonly observed in the soil body.
