Rocks and Minerals
RAMM holds a comprehensive collection of local rocks and minerals that reflect the geological diversity of Devon. They draw us a picture of the county as we have never seen it before: a terrain covered by ancient tropical reefs or vast desert dunes, an area disturbed by sudden rock avalanches or erupting volcanoes.
Devon’s rolling hills, multi-coloured cliffs, narrow gorges and steep valleys tell us a story of an eventful past. Red sandstones, hard granites or grey slates are the main characters in a tale that started about 400 million years ago on the southern hemisphere of the Earth.
The local minerals reflect the long and eventful mining history of the county and Southwest England. Essential metals such as copper and tin to precious silver and gold are part of the region’s heritage. Arsenic was also mined in Devon and Cornwall. The mineral collection also includes specimens from all the world.
