| Record Name | MUK002 Coppermine shaft at Long Scar, Great Sleddale. |
| Record Description | Details all from Dunham, K.C. and Wilson A.A. 1985. Geology of the North Pennine Orefield, Vol 2 Stainmore to Craven. BGS. HMSO.Chapter 9, as follows:
'A shaft on the south-east side of the streamsunk in 1912-14 tested the vein for copper ore. The base of the Main Limestone on the footwall must be about 30ft (10m) below surface but the exact depth of the shaft is not known. The dump contains vuggy veinstuff with pale mauve and amber fluorite, brown oxidised carbonate (?former ankerite, malachite,azurite, and small amounts of chalcopyrite. Type Locality of the inner F Zone of Small, A.T. 1978. 'Zonation of Pb-Zn-Cu-F--Ba mineralisation in part of the North Yorkshire Pennines'. Trans. Inst. of Min. Metall., Vol 87pp. B10-13.
The fault follows the cliff behind the shaft, striking N54 degrees E and dipping 72 degrees NW. Heavy silicification of the limestone accompanies the mineralisation.' |

| Additional Notes | Unusually, the spoil dumps of this mine shaft have not been destroyed by collection. For this reason this record is to be restricted.
Note the interesting highly coloured and varied metalophyte flora of lichen algae and bacteria on the mineralised cliff. |
