The Ordovician of the Ebbe Inlier (Rhenish Massif, western Germany) revisited Koch, L., Servais, T., Maletz, J., Vandenbroucke, T.R.A. & Verniers, J. Abstract: Outcrops of
Ordovician sediments in western Germany are of very
limited extent. In the
Ebbe Inlier (Rhenish Massif) strongly tectonized, mostly fine-grained
detrital Middle to Upper Ordovician rocks have been described since the
1910s. These sediments underwent a careful revision in the last 20 years.
Four formations, attributed to the Herscheid Group, yielded diverse fossil
assemblages (including trilobites, graptolites, ostracods, chitinozoans,
acritarchs and other groups) that allow attribution to age intervals between
the Abereiddian (Darriwilian) and the Streffordian (early Katian). The
sedimentary facies shows greatest resemblance to the successions of the
Condroz Inlier in Belgium. Palaeogeographically, they constitute the
southeasternmost part of eastern Avalonia.
