Iron Range
- For the former USAF Bomber base in North Queensland and the National Park, See Iron Range, Australia
The Iron Range refers to "numerous iron-producing ranges embraced within the Lake Superior Region." These cherty iron ore deposits are Precambrian in age for the Vermilion Range, while middle Precambrian in age for the Mesabi and Cuyuna Ranges. Similarly, the Gogebic Range in Wisconsin and the Marquette Iron Range and Menominee Range in Michigan. Natural ores and concentrates were produced from 1848 until the mid 1950s, when taconites and jaspers were concentrated and pelletized started to become the major source of iron production.
