Golden Hill Quarry, Devauden

This small disused quarry exposes rocks from deep within the Earth, beneath the outer crust. They were brought to the surface as a result of volcanic activity in the Carboniferous period (about 345 million years ago). The site gives us a rare insight into the composition of that portion of inner Earth known as the mantle. For this reason it is of national importance, and is frequently used for teaching and research.
