They truncate older laminae and are truncated by younger laminae. The erosional surfaces that separate “sets” of similarly oriented laminae are called “bounding surfaces”.

WebSeveral sedimentary structures that are commonly found in braided rivers are trough cross-bedding, upper planar, and ripple laminations. 1. Trough cross-bedding in channels. This occurs due to the migration of irregular dunes. 2. The coarsest sediment can be lower flat laminated if flow speeds are not fast enough to form coarse grained dunes.
