The Bergslagen project
In spring 2017, a new multidisciplinary survey project was initiated within the Bergslagen ore province, aiming to increase our understanding of the bedrock and to identify metals and minerals, both in situ and in mining waste material.
Increased demand for metals and minerals
The demand for metals and minerals has never been as high as today. The EU has adopted a special policy regarding so-called “critical materials”, which are materials needed in green technology such as electric cars, windmills and solar power plants. The demand for metals in general is also increasing. Climate changes and the switchover to fossil-free energy sources constitute challenges for meeting the future demand for natural resources.
Multidisciplinary studies combining new data with previously collected data gives better understanding of the genesis of the bedrock in Bergslagen, as well as the involved processes, and offers fundamental information that can be used as a base in future exploration for critical metals and minerals.
Investigations are conducted in four subprojects with the joint effort to meet the general aims and goals of the Bergslagen project; 1) local surveys, 2) regional surveys, 3) documentation of ores and industrial minerals, and 4) critical materials in Bergslagen.
Local surveys are conducted in three identified key areas in Bergslagen: the Ludvika area, the Norberg-Avesta area, and the Sala-Jugansbo area. These aim to update the geological, geophysical and geochemical databases to better understand ore-forming and geological processes in Bergslagen.
Regional surveys are conducted to identify features that are common for most parts of the area. Soil geochemical sampling is performed where no previous data exist regarding natural background concentrations of major and trace elements, as well as soil pH.
Ores, industrial minerals and rock types are documented in the Västmanland County, with the purpose to gain a complete picture of the potential for future exploitation of metals and industrial minerals in the area.
Primary and secondary occurrences of metals and resources are identified, investigated and described according to the list of critical materials adopted by the EU. This subproject is in part focused on rare earth element (REE) occurrences but also on the general mineral potential of the area.
