Rocks to riches Part two

Send us Fan MailThere are so many places across the north of England that show us how the human race has depended on rocks that I felt  this topic needed at least 2 episodes. The last episode explored the origins of stone axes, copper, iron and lead ores, coal and graphite. This one visits 6 more places that have examples of very different uses for the geological resources of our planet. First we are off to the City of Durham.
