| Description: | Bog iron ore from an iron pan on the west shore of Kirst Shun, one quarter of a mile north-north-east of Clothister Hill, Shetland. It is recorded that in 1874 Shetland produced 692 tons of bog iron ore. British Geological Survey Petrology Collection sample number MC 7361. Evidence for the earliest traces of iron-making in Scotland can be seen in the bloomeries where local bog iron ore of recent origin was smelted. They arose in several areas due to the availability of bog iron ore and a good supply of timber for charcoal making. Bog iron ore is a general term for soft, spongy and porous sedimentary deposits of impure hydrous iron oxides formed in bogs, swamps, marshes, peat mosses and shallow lakes from the chemical precipitation from iron-bearing waters and by the oxidizing action of algae, iron bacteria or the atmosphere. |
