Hiatuses and condensation: an estimation of time lost on a shallow carbonate platform

On shallow carbonate platforms, the sedimentary record is highly fragmentary because low accommodation commonly leads to non-deposition, erosion, reworking, and condensation. Consequently, it is difficult to quantify the time that is actually recorded and to estimate sedimentation rates. The Berriasian platform in the Swiss and French Jura Mountains offers an opportunity to address this problem. Facies evolution through time displays deepening-shallowing trends of different orders, resulting in a hierarchical stacking of sequences. The sequence- and cyclostratigraphic analysis relates these sequences to orbital cycles with durations of 20, 100, and 400 kyr.
