Cimmerian unconformity
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.

WebJan 1, 1993 · The earliest and most significant of these unconformities occurs consistently in the Aalenian and is characterized by progressive truncation of stratigraphy throughout the North Sea area in a broadly concentric but asymmetric subcrop pattern over an area with a diameter greater than 1250 km.
WebJan 1, 2024 · Abstract Joint results of two independent international studies on the erosional impact of the ‘Late Cimmerian Unconformity’ (LCU), a Late Jurassic–Early Cretaceous erosional event, are presented. The potential impact on the reservoir and sealing potential of adjacent strata are discussed. WebThis unconformity represent a major hiatus that occurred between the Late Jurassic limestone-dominated Masajid Formation and Early Cretaceous sand-dominated Alam El Bueib Formation. This time gap affected mainly the structural highs in the central part of the Western Desert and northern Sinai Peninsula.
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.
