GEOL110 – Week 5 Introduction to Sedimentary Rocks Introduction • Sedimentary rocks occur in layers (beds). – Record the WebIn 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.
