Graded bedding is a sorting of particles according to clast size and shape on a lithified horizontal plane. The term is an explanation as to how a geologic profile was formed. Stratification on a lateral plane is the physical result of active depositing of different size materials. Density and gravity forces in the downward movement of these materials in a confined system result in a separating of the detritus settling with respect to size. Thus, finer, higher-porosity clasts form at … WebUsed in this context, trace fossils can furnish valuable information concerning (1) general depositional processes, (2) episodes of local deposition and erosion, and (3) characteristics of currents, substrate consistency, and in some instances, causes of sediment sorting.
