A paraconformity is a type of unconformity (gap in the geologic system) in which there is no evidence of a gap in time, because the planes above and below the gap are parallel and there is no evidence of erosion.

According to Ariel R. Roth a paraconformity occurs "when a part of the geological column is missing in the [sedimentary] layers." [1]

The arrows point to paraconformities at the Grand Canyon.

William R.Corliss, a cataloger and writer on scientific anomalies, wrote the following regarding paraconformities:

Potentially more important to geological thinking are those unconformities that signal large chunks of geological history are missing, even though the strata on either side of the unconformity are perfectly parallel and show no evidence of erosion. Did millions of years fly by with no discernible effect? A possible though controversial inference is that our geological clocks and stratigraphic concepts need working on." William R. Corliss, Unknown Earth (Glen Arm, Maryland: The Sourcebook Project, 1980), p. 219.[2]

Ariel R. Roth wrote regarding paraconformities the following:

Paraconformities challenge the geologic timescale. The lack of evidence of time at the surface of the underlying layers of a paraconformity, especially the lack of erosion, suggest that the long ages never occurred.[3]

Young earth creationists cite various pieces of evidence and arguments why they believe that paraconformities challenge to the old earth uniformitarian geology paradigm.[4][5]
