Early diagenetic dolomitization and dedolomitization of Late Jurassic and earliest Cretaceous platform carbonates: A case study from the Jura Mountains (NW Switzerland, E France)

Early diagenetic dolomitization is a common feature in cyclic shallow-water carbonates throughout the geologic record. After their generation, dolomites may be subject to dedolomitization (re-calcification of dolomites), e.g. by contact with meteoric water during emersion. These patterns of dolomitization and subsequent dedolomitization frequently play a key role in unravelling the development...

Tethyan-to-boreal correlation in the Kimmeridgian using high-resolution sequence stratigraphy (Vocontian Basin, Swiss Jura, Boulonnais, Dorset)

Colombié, C. ; Rameil, Niels

In: International Journal of Earth Sciences, 2007, vol. 96, no. 3, p. 567-591

Ammonite biostratigraphy plays a central role in the definition of Jurassic stratigraphy. Nevertheless, the strong provincialism of European ammonite species during the Kimmeridgian is a long-standing problem in correlation attempts between the boreal and Tethyan faunal realms. Moreover, the sequence-stratigraphic interpretations for northern and southern Europe given in the Jurassic...

Thèse de doctorat : Université de Fribourg, 2005 ; Nr. 1493.

The present study aims at a better understanding of the development of the Swiss and French Jura platform during the Jurassic/Cretaceous (J/K) boundary interval, with a special focus on the Tithonian stage. Nine reference sections were measured in the Jura Mountains of northwestern Switzerland and eastern France, in the Helvetic Alps, and in the Subalpine Ranges in south-eastern France. Their...
