Ametistsjön Ärten naturreservat

Geological treasure The amethyst deposits of the Pea are unique in our country because there are not many other deposits of this kind. The area is geologically interesting not only because of these deposits but also because of the special composition of the bedrock, the tectonic conditions, the geological history and the way the amethysts were formed. Tectonics is about the structure of the Earth's crust and the processes that created it. The bedrock here consists mostly of sandstone, but also of syenite porphyry and Värmland granite.

Old reserve with its own report The reserve was established in 1976 with the aim of protecting the geological values of the area. A report has been published by the County Administrative Board, which describes the geology of the area in more detail. It is called 1976:1 Inventory and planning of Lake Ärten "ametistsjön" and can be borrowed from Falu City Library.
