===Geology===

The northern foothills of the [[Rhenish Massif]] are characterised by the distinctive rock formation of the bare mountain slopes through which run coal-bearing layers which formed during the [[carboniferous]] period. Here the Ruhr cuts more than 50 meters deep into this [[Mittelgebirge]]. This natural [[erosion]] partly uncovered these mineable [[bituminous coal|black coal]] deposits, which enabled their exploration and extraction using [[adit]]s. However, the coal-rich layers became ever deeper as one progressed northward, which required setting up [[mining|mines]] to extract the black coal. In contrast, the broad [[bayou]] (dead arm of a river) of Styrum borough is characteristic of the features of the Lower Rhine Plain.<ref name="Mülheim Geology">{{cite web|url=http://www.muelheim-ruhr.de/cms/muelheim_im_wandel_dererdgeschichte.html|title=Mülheim an der Ruhr official website – Eine kurze Geschichte zur Geologie und zur Geographie des Stadtgebietes|access-date=2010-04-19|publisher= [[File:Flag of Germany.svg|border|10px]] {{fontcolor|Green|(in only [[German language|{{fontcolor|Green|German}}]])}} [[copyright|©]] 1998–2010 MST Mülheimer Stadtmarketing und Tourismus GmbH}}''</ref>
