Description
Summary:The Devonian-Carboniferous Boundary sections at Hasselbachtal, Oese, Apricke, and Ober-Rödinghausen, all located at the northern margin of the Rhenish Mountains, were measured in detail. A semi-quantitative evaluation of the carbonate content and resulting carbonate curves permitted a highly exact correlation of these sections. This result is supported by data on ammonoid records and volcanoclastic horizons. Carbonate fluctuations within the Hangenberg Limestone are regarded as showing a 100000 years cyclicity. A new ammonoid genus <i>Hasselbachia</i> n. gen. and the species <i>Paprothites ruzhencevi</i> n. sp. are described. Among the rugose corals, a new species <i>Hillaxon hassel</i> n. sp., is erected. <br><br> Die Devon/Karbon-Grenzprofile Hasselbachtal, Oese, Apricke und Ober-Rödinghausen, alle auf der Nordflanke des Remscheid-Altenaer Sattels gelegen, wurden detailliert aufgenommen. Die halbquantitative Ermittlung des Karbonatgehaltes und daraus resultierenden Karbonatkurven eignen sich für eine sehr genaue Korrelation dieser Profile, die durch Funde von Ammonoideen sowie durch vulkanoklastische Horizonte unterstützt wird. Wechsel im Karbonatgehalt werden als 100000 Jahres-Zyklizität gedeutet. Die neue Ammonoideen-Gattung <i>Hasselbachia</i> n. gen. sowie die Art <i>Paprothites ruzhencevi</i> n. sp. werden beschrieben. Unter den rugosen Korallen wird die neue Art <i>Hillaxon hassel</i> n. sp. errrichtet. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.20030060105" target="_blank">10.1002/mmng.20030060105</a>
