Alum Shale Formation - Wikipedia
At the same time it is rich in aromatic hydrocarbon attributed to post-depositional irradiation damage induced by uranium concentration in the shale. Alum shale also contains enhanced levels of radium as a result of uranium decay. Between 1950 and 1989, Sweden used alum shale for the uranium production.

During primarily the 1970s, shale was utilised for beneficiation of uranium by leaching with sulphuric acid. The alum shale in the areas of Närke, Västergötland and Öland (south-central Sweden) has Si, Al and Fe (in oxide form) as the major elements and contain, in addition, around 5–7% S and < 1% Ca figured on the shale itself, disregarding
