geology of Norway
encompasses the history of earth that can be interpreted by rock types found in Norway, and the associated sedimentological history of soils and rock types.
The Norwegian mountains were formed around 400 million years ago (Ma) during the Caledonian orogeny.
Geological Norway is everywhere impressive present, interesting because of the visible structure, colors, and the way it makes a composition with the skies above, the water running over it, and between, creating waterfalls, streams and rivers, and because of that creating the right environment for plants and animals. The endless mountainous solidity creates an unforgettable powerful energy, makes you aware of space, of earth and universe, of height, depths, and yourself, in an overwhelming experience of natural majesty, where details become one with the wholeness of life.

When reading what Schist is, I become aware of what Arne Næss once said about a mountain. He saw it as a huge collection of minerals.
