本文对黄河口及其近岸区１００余个表层沉积物中的粘土矿物进行了定性及半定量分析，首次对研究区存在的４类粘土矿物的“种”属特征作了较精确的鉴定。同时根据粘土矿物的分布图式探讨了黄河细粒物质入海后的运移扩散规律。
In this paper, qualitative and semi-quantitative analysis of clay minerals in more than 100 surface sediments in the Yellow River estuary and its nearshore area has been carried out for the first time to appraise the species characteristics of four types of clay minerals in the study area for the first time. At the same time, the law of migration and diffusion of fine-grained materials in the Yellow River into the sea is discussed according to the distribution of clay minerals.
