The characteristics and significance of magnetic fabrics of muddy tidal flat

Conclusions The magnetic fabric parameterK of the tidal flat with the same material sources in the wide coastal zone is a high-resolution indicator for the recognization of sedimentary dynamically active zones of tidal flat, which indicates that the magnetic fabric method could be widely applied to the study of sedimentology, comparative sedimentology and sedimentary dynamics. The high and low values of magnetic fabric parametersq, F andL occur alternately, which indicates the presence of microbedding structures, such as small-scale sequences consisting of a single muddy layer and a sandy layer and small-scale sequence series. This indicates that the magnetic fabric analysis could be a new effective method for the study of sedimentary microstructure sequence series of tidal flats. The statistical results of parametersK, L, F andq have revealed that correlations between the variations of magnetic fabric parameters of sediments and the sedimentary dynamic environments are a new way for the studies of tidal flat types and sedimentation.
