Cross-bedding

（重定向自Cross bedding）

Cross-bedding in a sandstone dome in the Canyons of the Escalante.

Sand dune cross-beds can be large, such as in the Jurassic-age erg deposits of the Navajo Sandstone in Canyonlands National Park.

In geology, the sedimentary structures known as cross-bedding are the (near-) horizontal units that are internally composed of inclined layers. This is a case in geology in which the original depositional layering is tilted, and the tilting is not a result of post-depositional deformation. Cross-beds or "sets" are the groups of inclined layers, and the inclined layers are known as cross strata.
