Subaerial unconformity

In geology, a subaerial unconformity is a surface that displays signs of erosion by processes that commonly occur on the surface.[1] These processes generating the subaerial unconformity can include wind degradation, pedogenesis, dissolution processes such as karstification as well as fluvial processes such as fluvial erosion, bypass and river rejuvenation.[2]

Role in sequence stratigraphy

Subaerial unconformities are used as limiting surfaces that define sequences in sequence stratigraphy.[3] In this context they are synonymous with the terms lowstand unconformity, regressive surface of fluvial erosion as well as fluvial entrenchment surface and incision surface.[2]
