Rare mineral mining
« Thread Started on Apr 20, 2009, 3:54pm »
Here's a photo of a mineral sample I 'obtained' from a long derilict mine some 40 or so years ago, highly prized and extremely rare. A mineral format that is unique to one small area of Britain and has been mined continiously for thousands of years, it is still being deep mined today but its annual production is limited to kilos rather than tonnes, yet it still supports a viable industry ...................... any ideas?

Nope, don't recognise it Daz.
The only extremely rare mineral I know of is platinum, but thats only mined in South Africa and a part of Russia.

almost right, it is Blue John and from Derbyshire but not quite Buxton, the unique patterning of this fluorspar is only found within one small hillside called Treak Cliff in Castleton.
Beautiful stuff but an absolute bugger to work with, it has to be 'soaked' in resin first to ensure it doesn't literally drop to bits.
