Unconformities are surfaces that represent gaps in the geologic record that formed wherever layers were not deposited for a time or else layers were removed by erosion.
unconformity (plural unconformities) (nonstandard) A lack of conformity. (geology) A gap in time in rock strata, where erosion occurs while deposition slows or stops.
Formation of an Unconformity: An Unconformity may develop due to the changes in the process of deposition due to which there is a break in the deposition. This may also take place due to Upheaval of...
A surface between successive strata representing a missing interval in the geologic record of time, and produced either by an interruption in deposition or by the erosion of depositionally continuous...
