The millstone mine Minnesfjället
Waves-related structures in the ceiling reflect deposition in an ancient sea with early-life organisms.
The sub-Cambrian peneplane formed from Precambrian crystalline rock and is here, at mount Lugnåsberget, overlain by sedimentary rocks. The Minnesfjället mine is one of the few location where it is possible to observe the contact zone between the Precambrian basement and the oldest Cambrian deposits from below. The site is well known for its fossils, trace fossils and sedimentary structures, showing early life and palaeoenvironments. It also forms part of the mining history in Sweden, as mill stones have been quarried here for long time.
