Horizontal unconformity

Web25 okt. 2024 · An angular unconformity is an unconformity where horizontally parallel strata of sedimentary rock are deposited on tilted and eroded layers, producing an angular discordance with the overlying horizontal layers. How is horizontal unconformity formed? Unconformities occur when either erosion wears away rocks, or rock deposits never form. Weberosion. Here is an implication that an unconformity may be con- sidered great if there is a large "lost interval," even if it is incon- spicuous because the lower and upper beds are not discordant.
