Cimmerian unconformity

WebABSTRACT: Several regional or local unconformities occur in the latest Jurassic-Early Cretaceous sequences of the North Sea and adjacent areas. Each may have been identified locally as the “late Cimmerian unconformity,” a supposed major break at the base of the Valhall Formation (or Rødby Formation where the Valhall is locally absent). WebPalaeotethyan Ocean. This so-called Early (or: Eo-) Cimmerian Orogeny formed the Cimmerides, a more-or-less E/W-oriented mountain belt. The Upper Triassic-Middle Jurassic Shemshak Formation of northern Iran is commonly regarded as the product of the erosional denudation of the Cimmerides, i.e. the Cimmerian foreland molasse.
