Geology

The rocks are metamorphosed, volcanic to volcanosedimentary rocks of rhyolitic pyroclastic units and minor dacitic-rhyolitic volcanic to subvolcanic complexes. Mafic metavolcanic rocks are also found. They are underlain and overlain by siliciclastic metasedimentary rocks. These layers were deposited in a shallow marine environment within a continental back-arc system. Magmatic rocks formed during the volcanic activities are dated 1.91–1.88 Ga old. These old rocks host iron sulfides and manganese oxide ores with low contents of more noble metals.

Description

The Gruvmuseet Grängesberg is also known as Mojsen gruvcentrum or Gruvcentrum Mojsen (Mojsen Mining Centre), actually it is located at Grängesberg. The name Mojsen comes from the word mojs, which refers to dishes commonly found in commercial kitchens, such as soups and meat stews. Grängesberg was also known for its reclining beds, where miners could take a nap after their meal. So Mojsen became the nickname of the former miners' staff canteen, where the museum is located and afte which it was named. The mine is part of the mining area "på väster" (on the west side). Models, pictures and explanatory texts tell the story of local mining and life the mining community. The visit to the museum includes a guided tour of the show mine, which is adjacent to the museum and exhibitions. There are numerous heavy machines in the open air museum. Some examples are the Borraggregat Atlas Copco, Borraggregat Tampella, Borraggregat Tamrock, Lastmaskin ST5, and Lastmaskin ST8. Borraggregat translates drilling rig and Lastmaskin translates loader. Other remains of local iron mining remains are the Maskinhuset (Machine House), Cassels (Cassel’s Concert Hall), Disponentparken and the Lokmuseet (Locomotive Museum) to the south.

Iron ore mining at Grängesberg started on the surface, as always, but soon went underground. The mining method was skivrasbrytning (disc race mining) or blockrasbrytning (block race mining).

The mining museum and show mine are open only for a short time during summer. The numerous other sights like heavy machinery, open air museum, historic buildings and so on are freely accessible all year.
