Prison Camp Geology


    THE fascinating memoir, referred to below*, is worthy of notice, not only because it is a major contribution to front' petrology and deep-seated tectonics, but also because of the extraordinary conditions under which the research it records was carried out. The University of Edelbach was founded by French prisoners-of-war in Oflag XVIIA (1940-45). NcVcontent with lectures alone, the geologists made a thorough investigation of the area—only 400 metres square–enclosed within the barbed wire. No stone was left unturned, and trenches and secret tunnels provided many critical exposures. A microscope was constructed in the camp and equipped with polarizers improvised from piled cover glasses. Thin sections were mounted with a mixture of violin wax and edible fat. Only the determination of certain untwinned feldspars remained to be completed on the return to France.
