Inclined layered rocks
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 … See more Cross-beds can tell geologists much about what an area was like in ancient times. The direction the beds are dipping indicates paleocurrent, the rough direction of sediment transport. The type and condition of … See more • Cross-bedding animation from USGS • The Bibliography of Aeolian Research See more Cross-bedding is formed by the downstream migration of bedforms such as ripples or dunes in a flowing fluid. The fluid flow causes sand grains to saltate up the stoss … See more Rivers Flows are characterized by climate (snows, rain, and ice melting) and gradient. Discharge … See more WebRock layers are frequently inclined or folded. One or more folds may be exposed, or just dipping layers may be visible. Be Consistent When Painting Rocks The key to accurately portraying rock is to identify the thickness/spacing and dip of rock layers and fractures and keep these features consistent across your painting.
