Web31 Jul 2014 · Thin beds are a common occurrence in turbiditic, deltaic, and tidal series. They consist of alternating sand and clay layers that have a thickness of less than 50 cm. Outside these layer thickness, sand and clay are well-distinguished on classic logs and are not considered to be thin beds. WebTrough cross beds are most common in channelized or confined flows (rivers, tidal inlets and channels, rip currents). Three-dimensional underwater dunes tend to form at higher velocities than 2D dunes. Although SEPM nomenclature is widely used, deeply established terms such as troughs and tabular crossbeds are still popular.
