Allogenic and autogenic processes combined in the formation of shallow-water carbonate sequences (Middle Berriasian, Swiss and French Jura Mountains)

Tresch, Jonas ; Strasser, André

In: Swiss Journal of Geosciences, 2011, vol. 104, no. 2, p. 299-322

Sediment production and accumulation on shallow carbonate platforms are controlled by allogenic, externally controlled processes (such as sea level, climate, and/or platform-wide subsidence patterns) as well as by autogenic factors that are inherent to the sedimentary system (such as lateral migration of sediment bodies). The challenge is to determine how and in which proportion these...

History of the Middle Berriasian transgression on the Jura carbonate platform : revealed by high-resolution sequence- and cyclostratigraphy (Switzerland and France)

Tresch, Jonas ; Strasser, André

In: International Journal of Earth Sciences, 2010, vol. 99, no. 1, p. 139-163

The Middle Berriasian deposits of the Jura platform in Switzerland and France have already been well studied in terms of high-resolution sequence stratigraphy and different orders of depositional sequences (large-, medium-, and small-scale) have been defined. The hierarchical stacking pattern of the sequences and the time span represented by the investigated interval imply that sea-level...

History of a Middle Berriasian transgression (Switzerland, France, and southern England)

Tresch, Jonas ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 2007 ; no 1550.

Le but de cette étude est de corréler et d’interpréter les dépôts transgressifs de trois différentes zones de dépôt avec haute résolution: les carbonates marginaux de la plate-forme du Jura (Suisse et France) et de la région du Dorset (Angleterre). En plus, une coupe hémipélagique du bassin Vocontien (France) a été intégrée dans le schéma de corrélation haute résolution. La...

Origin of peloids in Early Cretaceous deposits, Dorset, South England

Samankassou, Elias ; Tresch, Jonas ; Strasser, André

In: Facies, 2005, vol. 51, p. 264

Peloids are ubiquitous components in modern and fossil carbonates. The term peloid is non-genetic because the origin of these grains and the pathways of their formation are not fully understood. Based on Berriasian material originating from Dorset, southern England, we report here on peloids that result from the more or less in-place breakdown of previously micritized bivalve shells. The...
