Help with ID maybe wrong forum

[stevegilbert]

Just wanted to say quick Hi from Dartford UK. I have inherited 4 interesting rocks, amongst other things and will be posting asking for help with what they are. Having said that the forum looks interesting so I may hang around. They are clearly not detector finds so you may tell me to go. However I like to think maybe my uncle found them whilst detectoring.

This is the first, may have uploaded wrong. It says on label from Boltsburn mine Weardale 29.09.26. I think it says it's Flourbar but presume it means its Flourspar. it measures 100mmx90mmx90mm and weighs 955grams it is purple ish in colour. Any advice most welcome
The second is below I think it may be quartz with pyrite. it weighs 3.2kg and measures 180mm x 140mm x 90mm

Any help be greatly appreciated many thanks Steve

Beautiful specimens from an old mine. The one with the label on it is a real treasure. did you research the mine? It was discovered in the early 1800's as a lead mine. In 1892 they found huge blocks of fluorite, also called "fluorspar", and then mined it for fluorite. Looks like all those specimens, except the white one, is fluorite. I can find no reference to any mineral called "floubar" so think it was a local spelling someone thought it was. Close enough. As the the other one it may be quartz with galena but the color on the photos if hard to determine. If it's gray its probably galena, yellow goldish is probably pyrite. Mine produced some of the finest fluorite cubes ever found and it's quality was fantastic with some sold to German microscope makers. Mine closed in 1932. To me those are real treasures. Probably not worth much but there's more to value than money.
