Scottish Lewisian Gneiss
Scottish Lewisian Gneiss refers to a group of rocks found primarily in the Outer Hebrides of Scotland. The rock group was named after the island of Lewis, as the rocks are very common there and form the island's bedrock.
The Scottish Lewisian is composed of various minerals such as feldspar, epidote and quartz, which create the unique patterns and colors.
The age of the Lewisian is estimated to be between 1700 million and 3000 million years, making the Lewisian the oldest rock in Europe and one of the oldest in the world!
