Nova Scotia has a long geological history dating back over a billion
years. The rocks found on land date back as far as 1.4 billion years ago. The
rocks offshore date back about 250 million years ago and show records of mountain
building, erosion of the mountains, earthquakes, volcanic eruptions and the collision of
the continents. During the early Devonian period, about 400 million years ago, Nova
Scotia was actually part of the African continent.
