The Långban Society was founded in 1983, and its members have a wide interest in the mineralogy, geology and history of a group of mines, most of which are situated in eastern Värmland, Bergslagen. It has about 50 members
In this area there is a small number of mines which for a long time have been known for their great number of minerals. These deposits are Långban and its "satellites" Harstigen/Pajsberg, Jakobsberg, Nordmark and Sjögruvan. Their common denominator is that they have been mined for manganese oxide ore, which distinguishes them from most other mines in the Bergslagen district. Enrichment of several uncommon elements (antimony, arsenic, lead, boron, beryllium, etc.) has together with the complex redox chemistry of manganese led to an intriguing mineralogy. For the past 150 years geologists and mineralogists have been studying these occurrences and published a vast number of papers on the mineralogy, ore geology, etc. of these mines.
Activities and aims
The Långban Society serves as a forum for like-minded people,
amateurs as well as professionals, who actively wish to exchange
information and knowledge about mineral findings, new literature
pertaining to the Långban mines, etc. The object of the Society is:
