SGU – experts on Sweden’s geology

Open archive with information on Swedish geology

Founded in 1858, Geological Survey of Sweden – SGU – has been mapping the geology of Sweden for over 150 years. The national drill core archive, in Malå, is one of the world’s largest, featuring over 3000 kilometres of drill cores from across the nation. The cores have been accumulated by the Government as well as private prospecting companies.
“The SGU archive is open and accessible to schools, universities and researchers in addition to private companies, and plays a key role during the initial phase of new prospecting and mining projects,” explains Helge Reginiussen, a geologist based at SGU’s regional office in Malå.

In addition to drill cores, SGU’s Malå base is also home to extensive documentation in the form of maps, reports and analyses.

“SGU’s task is to administrate and make available all types of information on the geology of Sweden. We provide information on geological conditions and pursue dialogue with actors in the industry. It’s a case of constantly developing our stores of information to ensure they remain updated,” he says.

The world around, and the industry itself are constantly evolving. Resources previously of little interest for mining have suddenly gained the attention of prospecting companies. SGU is currently involved with the Barents Project, in Norrbotten, a mapping initiative tasked with providing better, more up-to-date information on the region as a whole.

“Norrbotten has a rich geological landscape, and there is considerable potential for unearthing deposits and raw materials unknown to us today. This is one of the reasons for carrying out the Barents project,” adds Reginiussen.
 “It could be a case of exploiting raw materials we were previously unable to utilise, or using a particular deposit because new methods of extracting the raw material have been developed. As a result, all the data we collect is held on file.”

SGU’s services are in constant demand across the mining sector, while the archive in Malå receives several hundred visitors every year. Companies are also able to rent space for their own drill cores on the site.

“SGU has extensive resources to help anyone with questions relating to the geology of Sweden. We offer a large bank of experience and expertise which we are happy to share, helping save time and money for commercial enterprises as well as public sector organisations,” ends Helge Reginiussen.

SGU supplies geological information to commercial enterprises as well as wider society. The organisation has both an economic- and eco- political mandate. SGU is based in Uppsala, Göteborg, Lund, Stockholm and Malå. One of these units is the Mining Inspectorate of Sweden, the nation’s official unit for cases relating to the Swedish Minerals Act. The Mining Inspectorate of Sweden has offices in both Falun and Luleå.
