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...
