Webstratification, the layering that occurs in most sedimentary rocks and in those igneous rocks formed at the Earth’s surface, as from lava flows and volcanic fragmental deposits. The layers range from several millimetres to many metres in thickness and vary greatly in … sedimentation, in the geological sciences, process of deposition of a solid material … WebSteno's laws of stratigraphy describe the patterns in which rock layers are deposited. The four laws are the law of superposition, law of original horizontality, law of cross-cutting relationships, and law of lateral …
WebBedding is defined as the arrangement of sedimentary rocks in beds or layers of varying thickness and character, oftentimes separated by bedding planes, which are planar or nearly planar surfaces that visibly separate each successive layer of stratified rock (of the same or different lithology) from the preceding or following layer.
Webstratification (Lat.,=made in layers), layered structure formed by the deposition of sedimentary rocks. Changes between strata are interpreted as the result of fluctuations in the intensity and persistence of the depositional agent, e.g., currents, wind, or waves, or in changes in the source of the sediment.
