    第四纪红色粘土网纹层的微形态特征

    THE MICROMORPHOLOGICAL CHARACTERISTICS OF VARIEGATED HORIZON IN QUATERNARY RED CLAY

    • 摘要: 对几个第四纪红色粘土剖面的网纹层进行了微形态研究。结果表明:其骨骼颗粒以石英为主,呈斑晶状分布;由于大裂隙高度发育,土体呈典型的棱块状结构;其土壤基质由三种各具不同微形态特征的类型所组成,它们处于一动态变化过程之中;土体中亦可见较多铁质胶膜出现。

       

      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.
