FROM LOCAL PATRIOTISM TO A PLANETARY PERSPECTIVE Science, Technology and Culture, 1700–1945 Series Editors David M. Knight University of Durham and Trevor Levere University of Toronto Science, Technology and Culture, 1700–1945 focuses on the social, cultural, industrial and economic contexts of science and technology from the ‘scientific revolution’ up to the Second World War. It explores the agricultural and industrial revolutions of the eighteenth century, the coffee-house culture of the Enlightenment, the spread of museums, botanic gardens and expositions in the nineteenth century, to the Franco-Prussian war of 1870, seen as a victory for German science. It also addresses the dependence of society on science and technology in the twentieth century. Science, Technology and Culture, 1700–1945 addresses issues of the interaction of science, technology and culture in the period from 1700 to 1945, at the same time as including new research within the field of the history of science.

This material, mainly consisting of fragments from Mesozoic rocks, is locally called Bunte Brekzie (colourful or polymictic breccia). The grain size ranges from house-sized blocks to fine dust. The top of the polymictic breccia shows a strong relief. It is overlain by suevite, an impact breccia with an appreciable amount of impact melt particles. It is characterised by rock fragments mainly from the crystalline basement and by vesicular, glassy ballistic bombs, locally called Flädle (pancakes). Suevite was deposited as hot fallout from the impact plume. It is found in small batches, and it was not recognised until the 1960s that these batches are only the sparse remains of a once continuous ejecta blanket (photo: Kölbl-Ebert). 3 1.4 Faults in Ziswingen quarry (Ries Basin): Huge, fractured limestone blocks moved along listric faults down into the initial crater. These faults are due to the gravitational reorganisation of the terrain after the impact (photo: Kölbl-Ebert). 4 1.5 Lacustrine limestone of the post-impact Ries lake at Büschelberg quarry (Ries Basin): The limestone is built up by algal reefs. Until the early 1960s, these were interpreted as precipitates of thermal springs caused by Ries volcanism. Similar deposits also occur at the Steinheim Basin (photo: Kölbl-Ebert). 5 1.6 Oblique view over the Rhine-Graben towards the Swabian Tableland and the Alps in the far background (drawing by Hans Cloos; from Hans Cloos: Gespräch mit der Erde, © 1947 Piper Verlag GmbH, München). 6 x From Local Patriotism to a Planetary Perspective 1.7 The Swabian Volcano: Randecker Maar in the foreground and Limburg Mountain in the distance. Due to erosion, the diatremes of the ‘Swabian Volcano’ are cut in different levels. On top of the Swabian Alb’s surface they appear as shallow depressions. In the foreland, the diatreme fillings are harder than the surrounding clay-rich country rock and form cone-shaped hills (photo: Kölbl-Ebert). 6 1.8 The Swabian Volcano: Chaotic vent breccia in the diatreme at Neuffener Steige (photo: Kölbl-Ebert). 8 1.9 Striation at Gundelsheim quarry (east of the Ries Basin): The upper surface of Late Jurassic limestone is polished and shows numerous parallel scratches resembling glacial action. Polish and striae were caused by the horizontal transport of the polymictic breccia during impact explosion (photo: Kölbl-Ebert). 11 1.10 Ries model test crater at Swinemünde by Walter Kranz (from Kranz 1912: 5). 16 1.11 Reuter’s blocks: Reworked distal Ries ejecta (Upper Jurassic limestone) within sandy Molasse sediments of the northern Alpine foreland (photo: Kölbl-Ebert). 18 1.12 Sketch of the central volcanic Ries explosion (Schuster 1926, courtesy of Stadt Nördlingen). 20 1.13 Suevite from Ries Basin (photo: Kölbl-Ebert). 21 2.1 Meteor Crater in the 1930s (Stutzer 1936a: 1). 32 2.2 Otto Stutzer argued in 1936 for an impact origin of the Ries and Steinheim Basins (photo from Jurasky 1937: 3). 39 3.1 Richard Dehm denied a central explosion at the Ries Basin and opted alternatively for smaller, local volcanic explosions to explain the widespread brecciation (photo from Fahlbusch 1996: 297). 67 3.2 Reinhold Seemann was the main promoter of the idea that the features of the Ries Basin evolved through a long history of gradual tectonic processes (photo from Hölder 1976: 204). 77 4.1 Drawing of a central mountain in a bomb crater of World War II by Ferdinand Trusheim (1940: 3). 100 4.2 Walter Kranz developed, in the 1910s and 1920s, the central explosion theory to explain the genesis of the Ries ‘volcano’ (source: Carlé 1987: 3). 106 List of Figures xi 5.1 Kaalijärv Crater on the Estonian island of Saaremaa in the Baltic Sea (photo courtesy of Tõnu Pani, University of Tartu, Estonia). 115 5.2 The Köfels landslide in the Ötztal, Austria, was interpreted by Walter Kranz as caused by a volcanic explosion, whereas Franz Eduard Sueß opted for a meteorite impact (photo: Kölbl-Ebert). 123 5.3 Köfelsite, a vesicular, slack-like glass from the Köfels landslide. The glass was formerly thought to be the product of an obscure type of volcanism, while Franz Eduard Sueß interpreted it as impact melt (photo: M. Ebert). 123 6.1 The astrophysicist Ernst Julius Öpik published on impact physics (photo courtesy of Armagh Observatory).
