Geognostische Übersichts-Karte von Deutschland, Frankreich, England

This geological map, titled "Geognostische Übersichtskarte von Deutschland, Frankreich, England und den angrenzenden Ländern" provides a detailed depiction of geological formations across parts of Western and Central Europe. Written in German, the map uses a variety of colors to represent different rock types, geological strata, or formations, and includes relief shading to integrate topography with geological features. It covers regions such as Germany, France, England, Belgium, Switzerland, and parts of Italy and Eastern Europe.

The map was produced during an era of significant advancement in the natural sciences, particularly in geology. By 1869, geology had established itself as a distinct scientific discipline, largely influenced by earlier works such as Charles Lyell's Principles of Geology (1830s), which advocated for uniformitarianism—the idea that Earth's processes occur gradually over long periods. This period also saw the rise of stratigraphy, the study of rock layers, and paleontology, which helped scientists correlate geological formations with specific time periods. The map reflects this growing emphasis on stratigraphic and regional geological studies, which were central to understanding Earth's history.

The Industrial Revolution, ongoing throughout the 19th century, had a profound impact on the production of geological maps. By 1869, geological mapping was closely tied to the exploration of natural resources such as coal, iron, and other minerals essential for industrialization. Germany, France, and England, in particular, were heavily involved in mining and resource extraction, and geological surveys like this one were invaluable for locating and managing these resources.
