Fluorite

Smallcleugh Mine, Nenthead, Alston Moor, Eden, Cumbria, England, UK
Locality type:Mine
Classification
Species:Fluorite
Formula:CaF2
Comments:Fluorite from the Nenthead mines dose not form in the abundance it dose in the Weardale area., being restricted to some localised areas in the mines of the Nenthead area. Judging from dump material above the Smallcleugh mine shallow shafts penetrating the sandstone members, fluorite appears to be ‘more abundant’. Although all the crystals so far collected are small from the sandstone horizons.
