RK 10 KO A — Geological map of the Rhine-Westphalian hard coal region 1: 10,000 (analogue)

The Geological Map of the Rhine-Westphalian Coal Region 1: 10 000 [IS RK 10] shows the spread of carbon-era hard coal fumes and sandstones. It also informs about the tectonics and the depth of the carbon surface. It was developed between 1949 and 1954 by the Office for Soil Research — the State Office of North Rhine-Westphalia, Krefeld — and reflects the geoscientific state of knowledge of the creation date. Today, the 58, high-resolution map sheets for dealing with questions about old mining are becoming increasingly important. The entire work of cards consists of five deliveries and accompanying cuts and explanations. Provision of the area map with cuts. The cuts have no georeferencing.
