===Characteristics of Fluvial Deposits===

The common properties of fluvial deposits are, they consist of sand and gravel grain size and also mud in floodplain deposits of meandering systems, and they have moderate to poor sorting. The deposits of point bars and braid bars are generally fining upward grain size. The repeat of channel shifting and bar migration of braided rivers produces vertical stacking of bar deposits can be separated by mudstones. And the repeat of meander migration produces vertical stacking of fining upward succesion in meandering river deposits. Many sediment structures like planar and trough cross-bedding, upper-flow-regime planar bedding, and ripple-marked surface occur in fluvial deposits. From fluvial deposits, the paleocurrent can be determined especially in meandering rivers. And fluvial deposits can also contain a variaty of fossil hard parts of terrestrial animals and also trace fossils which are created by both plants and animals.
