Rate and synchronicity of environmental changes on a shallow carbonate platform (Late Oxfordian, Swiss Jura Mountains)

Strasser, André ; Védrine, Stéphanie ; Stienne, Noémie

In: Sedimentology, 2012, vol. 59, no. 1, p. 185–211

Recent global change occurs within decades and leaves a significant imprint on shallow carbonate platforms. To what extent can rate and synchronicity of environmental changes in the past be evaluated in order to allow comparisons with the processes and products of today? Sections of a carbonate-dominated platform of Late Oxfordian age have been logged in detail in the Swiss Jura Mountains. The...

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

Strasser, André ; Védrine, Stéphanie

In: Perspectives in Carbonate Geology: A Tribute to the Career of Robert Nathan Ginsburg, 2009, 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...

Astronomical time scale for the middle Oxfordian to late Kimmeridgian in the Swiss and French Jura mountains

Strasser, André

In: Swiss Journal of Geosciences, 2007, vol. 100, no. 3, p. 407-429

Detailed investigation of facies and sedimentary structures reveals that, during the Middle Oxfordian to Late Kimmeridgian, the shallow carbonate platform of the Swiss and French Jura Mountains recorded high-frequency sea-level fluctuations quite faithfully. The cyclostratigraphic analysis within the established biostratigraphic and sequence-chronostratigraphic framework implies that the...
