Cyclostratigraphy of shallow-marine carbonates – limitations and opportunities

Strasser, André

In: Stratigraphy & Timescales, 2018, vol. 3, p. 151–187

The sedimentary record of ancient shallow-marine carbonate platforms commonly displays a stacking of different facies, which reflects repetitive changes of depositional environments through time. These changes can be induced by external factors such as cyclical changes in climate and/or sea level, but also by internal factors such as lateral migration of sediment bodies and/or changes in the...

Controls on facies mosaics of carbonate platforms: a case study from the Oxfordian of the Swiss Jura

Strasser, André ; Védrine, Stéphanie

In: Special publication of the International Association of Sedimentologists, 2009, vol. 41, p. 199–213

Modern shallow-water carbonate systems commonly display a complex pattern of juxtaposed depositional environments with a patchy facies distribution (facies mo saics). On ancient carbonate platforms, the reconstruction of lateral facies distribution is often hampered not only by discontinuous outcrop but also by lack of suffi ciently high time resolution. This case study from the Oxfordian (Late...

The paleoecological significance of nerineoid mass accumulations from the Kimmeridgian of the Swiss Jura Mountains

Waite, Richard ; Wetzel, Andreas ; Meyer, Christian A. ; Strasser, André

In: Palaios, 2008, vol. 23, no. 8, p. 548-558

The Kimmeridgian shallow-water carbonates of the Swiss Jura Mountains display stratigraphic levels containing mass accumulations of nerineoidean gastropods. The macro- and microfacies of the rocks with these nerineoidean assemblages suggest that their occurrence was related to water depth, physical energy within the habitat, sedimentation rate, substrate stability, and food supply. Typical...

The Aptian, Albian and Cenomanian of Roter Sattel, Romandes Prealps, Switzerland: a high-resolution record of oceanographic changes

Strasser, André ; Caron, Michèle ; Gjermeni, Maksim

In: Cretaceous Research, 2001, vol. 22 (2), p. 173

The Aptian–Lower Turonian hemipelagic sediments of Roter Sattel in the Swiss Prealps are well dated by planktonic foraminifera. Stacking pattern of the limestone-marl alternations and facies evolution allow the identification of sequence boundaries, transgressive surfaces, and maximum-flooding events or condensed sections on at least two hierarchical levels. Calibrated by a precise...
