Encyclopedia > Rupelian

The Rupelian (also known as Stampian, Tongrian, Latdorfian, or Vicksburgian) is the first of two stages of the Oligocene Epoch. It spans the time between 33.9 ± 0.1 Ma and 28.4 ± 0.1 Ma (million years ago). Faunal stages are a subdivision of geologic time used primarily by paleontologists who study fossils rather than by geologists who study rock formations. ... The Oligocene epoch is a geologic period of time that extends from about 34 million to 23 million years before the present. ... The word epoch can mean either an interval of time, or a particular point in time used as a reference point. ... Mega-annum, usually abbreviated as Ma, is a unit of time equal to one million years. ...

Gaemers, P.A.M. Refined correlations by means of lithostratigraphy and gadid otolith zonation of the Rupelian of the North Sea basin: a progress report.
The frequency of otoliths in Rupelian sediments is usually low due to poor conditions in most marine environments.
A high abundance of otoliths is often remarkable in horizons within the septaria clay with the highest concentrations of calcium carbonate in calcareous intervals and in calcareous beds intercalated in lime-free intervals.

At the beginning of the Rupelian period the North Sea transgressed onto the southern foreland filling up the existing topography.
During Rupelian and Chattian times the Lower Rhine Embayment and its adjacent areas were forced by the alpine compressional tectonic regime as well as by an increasing extensional tectonic influence due to the Cenozoic Central European rift system.
At the beginning of the Rupelian the subsidence at the northern margin of the variscan fold belt was very consistent from Belgium to Saxony-Anhalt.
