| Caption: | Bog iron ore from Lon Odhar, South Erradale, Gairloch, Ross and Cromarty. |
| Description: | The South Erradale bog iron ore is a good example of ore from the comparatively small pans that occur in the Loch Maree area were associated with the long history of bloomeries and furnaces in the area. British Geological Survey Petrology Collection sample number MC 7359. An early analysis by Ivison Macadam of two samples of South Erradale bog iron ore are sample a, 70.88 per cent ferric oxide; 49.61 per cent metallic iron; 7.48 per cent silica. Sample b, 66.68 per cent ferric oxide; 46.67 per cent metallic iron and 8.24 per cent silica. It is thought that the deposits were so small and few that the local bog iron ores would have been exhausted in early times and that iron would have been imported from elsewhere, possibly haematite from Cumberland and clayband ironstone from Fifeshire. |
