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). WebLateral meteoric recharge may have occurred as a result of two separate uplift events (Late Cimmerian Unconformity and Late Aptian Unconformity) and the related exposures of carbonates to the north of the study area during the Early Cretaceous. This palaeohydrological circulation brought about a significant reduction of porosity (from 40% …

"WebThe ‘mid-Cimmerian’ unconformity was thought to be the most profound. A key question that was asked was whether Cimmerian tectonic events were related to continental collision or rather a response to (minor?) plate geometry reorganizations and/or to subduction-accretion ‘anomalies’ broadly affecting the kinematics of convergence. 3.

The Cimmerian Orogeny was an orogeny that created mountain ranges that now lie in Central Asia. The orogeny is believed to have begun during the Late Triassic about 240–200 million years ago, when parts of the Cimmerian continent collided with the southern coast of Kazakhstania and North and South China, closing the ancient Paleo-Tethys Ocean between them. Blocks that derive fro… WebAn unconformity is a large gap in the stratigraphic record that formed when deposition ceased for a considerable time. Most unconformities have resulted from relative uplift, which causes the erosion of some of the previously formed record. Wherever sedimentary sequences have been studied, they are interrupted by such gaps.
