Mining in Cornwall and Devon - Wikipedia

The intrusion of granite into the surrounding sedimentary rocks gave rise to extensive metamorphism and mineralisation. As a result, Cornwall was one of the most important mining areas in Europe until the early 20th century. It is thought that tin ore (cassiterite) was mined in Cornwall as early as the Bronze Age.[citation needed] Over the years, many other metals (e.g. lead and zinc) have ...

These quarries are steep-sided and deep, exploiting high-quality granite that is under the ground surface and therefore not weathered by wind and rain. The stone shaping or dressing was usually done at the quarry and, because of the emphasis on quality, large quantities of stone were rejected and dumped nearby, having been wheeled along tramways to be tipped onto ‘finger dumps’ of waste rock.
