The research on the mineral characteristics of sediment and the responce to the hydrodynamic conditions of the tidal flat, at the northern Yellow River Delta
黄河口粉质土矿物成分特征及对水动力条件响应的研究

The road paved across the tidal flat is perpendicular to the propagating direction of waves in the Yellow River Delta,which makes a sharp difference on the hydrodynamic condition of both sides of the road.We selected two representative research regions on both sides and took some sediment samples respectively.The X-ray diffraction phase analysis shows the characteristics of the mineral components and their contents which respond to the hydrodynamic conditions.In general,the content of detrital minerals increases in intense hydrodynamic condition.It is manifested more prominently in the superficial layer of the sediment.
