Cong Youzi Han Guozhong (First Institute of Oceanography,SOA,Qingdao,266003,China)Li Congxian Chen Qingqiang (Shanghai Tongji University,Shanghai,200092,China)  
The measurements and analyses of sedimentary dynamics and magnetic fabrics were done for modern tidal mud flat sediments at the coast of Qikou in Hebei Province and Nanhui in Shanghai and also for subrecent tidal flat Sedimentary Profile at Caoyangxincun in Shanghai during 1988 to 1993.Value characteristics of magnetic fabric parameters of different modern coastal tidal flat sediments with the same sources show:high tidal flat has high K value,mesotidal flat has low K value and low tidal flat has middle K value.The measurement results of magnetic fabric of the tidal mud flat sedimentary profile in subrecent open coast show that K is the high resolution parameter to differentiate dynamic zones of tidal flat deposition,P,L,F,and q are those to analyze tidal flat sedimentary textures,and q is that to study tidal flat sedimentary microstructures and tidal flat storm events,and assemblage of K,P,L,F and q can be used to distinguish,with high resolution,low tidal flat sedimentary facies and sublittoral zone sedimentary facies.
