Stop exploration and mining of alum shale in

With this petition we want to stop the plans for mining in alum shale in Oviken and achieve a change to the mineral law to give municipalities the opportunity to exercise a veto right as part of the permit process regarding all forms of exploration, processing and extraction from alum shale.

Uranium mineralization in the Alum Shale Formation (Sweden ...

In southern Sweden, where Alum Shale underwent fairly shallow burial, uranium concentrations have no mineralogical expression except a rather high U content of biogenic phosphates. Calcite concretions (beefs) and fractures recorded the migration of hot overpressured hydrocarbons and brines from thermally mature areas to immature Alum Shale. However, thermal maturation and fluid migration

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.

The Alum Shale represents slow deposition in shallow, near-anoxic waters that were little disturbed by wave- and bottom-current action. The Cambrian and Lower Ordovician Alum Shale of Sweden has been known for more than 350 years. It was a source of potassium aluminum sulfate that was used in the leather tanning industry, for fixing colors in textiles, and as a pharmaceutical astringent. Mining the shales for alum began in 1637 in Skåne. The Alum Shale
