WebSedimentary structures are commonly formed as a result of erosion, deposition, or because of postdepositional deformation of sediments. Understanding the mechanisms by which sedimentary structures form is an important tool for geologists to understand the evolving depositional record. WebApr 13, 2024 · Abstract Glauconite is an authigenic clay mineral that is common in marine sedimentary successions. Dating of glauconite to determine the depositional age of sedimentary sequences has a long history but has fallen into disfavor due to the difficulty of obtaining “pure” glauconite separates.
