Abstract:
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.
