This volume contains 16 papers that all deal with the Refrath 1 Borehole. This borehole is located in the Bergisch Gladbach-Paffrath Syncline (Ardennes-Rhenish Massif, Germany) specifically to study the poorly known Upper Devonian (Famennian) sediments. The borehole was funded by the Geological Survey of North Rhine-Westphalia. Although the initial emphasis was on the regional geology and the geological mapping, the discovery in the borehole of many different fossil groups initiated research on palaeontology and biostratigraphy together with sedimentology, facies, thermal maturity and organic geochemistry. Hence, this volume on the Refrath 1 Borehole clearly demonstrates how a seemingly routine Geological Survey NRW geological and engineering geological mapping project triggered a multi-disciplinary research project whose results are of international interest.

Ce volume contient quinze articles consacrés à divers aspects de l'étude
du sondage Refrath 1. Ce sondage, implanté dans le synclinal de Paffrath,
se localise dans la partie nord-ouest du Massif schisteux rhénan, à quelques
kilomètres de la ville de Cologne. Après une description sédimentologique
des 53 m du sondage, consistant essentiellement en mudstones et siltites partiellement carbonatés du sommet du Famennien, les auteurs envisagten l'interprétation sédimentologique (il s'agit de turbidites), la minéralogie
des argiles, la géochimie organique et la description des restes fossiles.
La richesse en faune et flore est en effet remarquable et justifie ce travail.
On passe en revue successivement les palynomorphes, les plantes, les
hétérocoralliaires, les brachiopodes, les mollusques, les ostracodes, les
échinodermes, les conodontes et les poissons. Chacun de ces groupes est
richement illustré, faisant de cet ouvrage un bel exemple d'exploitation
multidiscipliaire d'un sondage.
