Angular unconformity

Term · Oil and gas · MLC-T-OAG-000121

A type of unconformity where younger sedimentary layers are deposited on top of older, tilted or folded strata, with an angular discordance between the two sets of layers. This indicates a period of deformation, erosion, and subsequent deposition. The contact surface represents a gap in the geologic record, often marking a change in depositional environment or tectonic activity.
