“…In the Ruhr Basin, both cyclothems are also complex, M11 containing the Wasserbank Sst. interpreted as an incised valley fill [15] and Y4 the coarse-grained Sarnsbänksgen Sst which locally erodes through the underlying marine band [14] [28] [183]. Cyclothem M10 (Neuflöz Sst.)…”

Upper Carboniferous successions in European sedimentary basins contain cyclothems related to glacial cycles of approximately 100 Ky duration. Within the UK Pennine Basin both simple and complex cyclothems are recognized. In the latter, mid-cycle deltas were flooded by sea-level rises, possibly related to short period orbital forcing events. They were followed by late cycle forced regression delta channels and then by incised coarse-grained channels active after the glacial maximum. Other European successions commonly contain coarse incised channel fills in the same cyclothems; these were deposited during colder glacial periods. Simple cyclothems formed during warmer periods contain only lobate mid-cycle deltas. The distribution of different cyclothem types is not random. Correlation with the eastern Australian succession using revised published radiometric dates from Eastern Europe suggests that the early Namurian C1 glaciation in Australia correlates with a group of Pennine complex cycles of late Pendleian to early Arnsbergian age. The C2 glaciation began just prior to the late Kinderscoutian and possibly lasted into the early Langsettian; the Pennine succession shows evidence for a number of colder periods with complex cycles, especially in the late Kinderscoutian and mid Marsdenian. The intervening period, particularly from Alportian to mid Kinderscoutian was warmer.

“…Nach kurzzeitigen Meereseinbrüchen in den Gebieten der küstennahen Kohlenwälder stellten sich vorübergehend vom Meer beeinflusste aquatische Lebensgemeinschaften ein, die in ihrer ökologischen Entwicklung gut untersucht sind [4]. Daneben beherbergten die Gewässer eine Arthropoden-Fauna aus Ostracoden, Conchostracen, Eurypteriden, ᮣ Euthycarcinoiden und Pfeilschwanzkrebsen.…”

Aus dem Karbon ergeben sich vielfältige Fragestellungen, die von übergeordnetem erd‐ und evolutionsgeschichtlichem Interesse sind: Welche Verbindungen bestehen zwischen der globalen Geographie vergangener Zeiten, dem Weltklima und ozeanographischen Veränderungen? Inwieweit wirken extraterrestrische, kosmische Einflüsse hier ausschließlich oder als Verstärkung mit? Wenn, besonders bei einschneidenden und länger andauernden globalen Veränderungen, Lebensgemeinschaften oder einzelne ihrer Glieder aussterben, wie verläuft die Phase der ökologischen Erholung und der Neubesiedlung solcher Lebensräume anschließend? In dem Maße, in dem wir auf der Grundlage eingehender systematischer Bearbeitungen fossiler Faunen und Floren solche Effekte abschätzen können, verstehen wir die Dynamik ganzer Lebensgemeinschaften im Verlaufe der Erdgeschichte. Dies ist eine Sicht‐ und Betrachtungsmöglichkeit, wie sie nur der Paläontologie mit ihrem über lange geschichtliche Zeiträume gerichteten Blick und ihrem Untersuchungsmaterial möglich ist.

“…The distribution of subsidence controls the lateral variation in the sedimentary environment in the Ruhr Basin during one base‐level cycle. This is best documented by the distribution of fossil assemblages (Böger, 1964; Rabitz, 1966) during marine transgressions.…”
