The Acasta Gneiss
The Acasta Gneiss of the Canadian North West Territories is the oldest preserved crustal rock in the world, dating back 4 billion years. The locality where these rocks are located is extremely remote and is only accessible by sea plane. As such this material will never be cheap to acquire, but is an important part of the ancient history of earth.
