| Description: | Dolomite vein in Carboniferous Burdiehouse or Grange Limestone from the Newbigging Mine, one mile west of Burntisland, Fifeshire. The dolomite is brown with lustrous crystalline surfaces, composed of an aggregate of anhedral ankerite of uniform grain size, and of a uniform pale brown tint. BGS Sample SL 172. British Geological Survey Petrology Collection sample number MC 7613. In the vicinity of faults, and along zones of crush and disturbance, there is a good deal of veining, individual veins sometimes extending to several feet in width. The vein-filling is mainly dark-brown crystalline ferro-dolomite, but coarsely crystalline white calcite veining is also common. An analysis of the ferro-dolomite showed the following composition: calcium carbonate 53.15 per cent, magnesium carbonate 25.97 per cent, iron carbonate 19.19 per cent, insoluble residue 0.46 per cent. |
