Hiatus 1


Hiatus 1 :

(n). Geology. A cessation in deposition of sediments during which no strata form or an erosional surface forms on the underlying strata; a gap in the rock record. This period might be marked by development of a lithified sediment (hardground) or burrowed surface characteristic of periods when sea level was relatively low. A disconformity can result from a hiatus. See: Conformable, Conformable, Disconformity, Eustasy, Hardground, Hiatal, Lithification, Sediment, Sequence Stratigraphy, Stratum, Unconformity
