摘要：

The morphology and composition were studied of a pair of soil profiles that had developed in a dike which was constructed 100 yr ago from marine sediments of silty clay loam texture. Both profiles had a weakly expressed A-B-C horizon sequence and strong structural development. They had Bm horizons and their exchange complex was dominated by magnesium ions. Organic carbon had accumulated in the surface mineral horizon at a maximum rate of 26.3 g m-2 yr-1. Adverse climatic conditions, typical for this and similar site locations, appeared to impose a limit on soil development.
