Kurzfassung
Die Schichtenfolge und die Verbreitung der Unterkreide im nordwestlichen Münsterschen Kreidebecken wurden in den vergangenen Jahren eingehend untersucht. Auch konnten lithologische und paläogeographische Probleme des Osning-Sandsteins, der an der gesamten nordwestlichen, nördlichen und östlichen Umrahmung des Münsterlandes immer schon recht gut aufgeschlossen war, geklärt werden. Nach Untersuchungen von H. ARNOLD, die 1964 in mehreren Darstellungen zur Oberkreide abgeschlossen wurden, verlor diese Formation in Westfalen, wohl auch bedingt durch fehlende Neuaufschlüsse, an Interesse. Verschiedentlich wurden noch Einzelarbeiten durchgeführt, doch große zusammenhängende Probleme nicht in Angriff genommen.
Abstract
During previous years the sequence and distribution of the Lower Cretaeeous in the northwestern Münster Basin were investigated in detail. In addition, lithological and paleontological problems of the Osning sandstone, relatively well exposed at the entire northwestern, northern and eastern margins of the Münsterland, could be c1eared up. Following the investigations by H. ARNOLD, published in several papers on the Cretaceous in 1964, this formation of Westphalia lost interest mainly due to the absence of new exposures. Isolated tasks were carried out occasionally but large-scale problems were not put into action. Not until ten years later, new activities were initiated regionally on a large scale which were brought about by intense drilling explorations on the one hand and the establishment of the International Research Program "Mid-Cretaceous Events" (MCE) on the other. These extensive activities resulted in new fundamental perceptions on the Albian, Cenomanian and Turonian transgression events as well as in new perceptions on the paleontology, lithology, stratigraphy, facies and paleogeography of the sequence in question.
