Definition of cross bedding
WebCross bedding. The fact that in many cases sediments tend to settle from water (or air) and fill in low areas with relatively flat layers is the basis of the principle of original horizontality, one of the important principles of relative geologic age. However, not all sedimentary beds are horizontal to begin with. WebSedimentary structures are the larger, generally three-dimensional physical features of sedimentary rocks; they are best seen in outcrop or in large hand specimens rather than through a microscope. Sedimentary structures …

WebJul 4, 2024 · What is the scientific definition of cross-bedding? noun. geology layering within one or more beds in a series of rock strata that does not run parallel to the plane of stratificationAlso called: false bedding. In geology, cross-bedding, also known as cross-stratification, is layering within a stratum and at an angle to the main bedding plane. The sedimentary structures which result are roughly horizontal units composed of inclined layers. The original depositional layering is tilted, such tilting not being the result of post-depositional deformation. Cross-beds or "sets" are the groups of inclined layers, which are known as cross-strata.
