Other articles where Lake Superior-type banded-iron formation deposit is discussed: mineral deposit: Iron deposits: Lake Superior and are called Lake Superior-type deposits.
Their individual sediment layers can be as thin as millimetre ( inch) or as thick as centimetres (1 inch), but the alternation of a siliceous band and an iron mineral band is invariable. In sum, the Jackson Mining Company did not have the financial and engineering capabilities to overcome the problem of distance between the Lake Superior iron ore deposits and the steel mills far to the south.
During the second half of the century, however, three interrelated developments opened the region. The Hamersley-type BIFs host the largest known BIF-hosted iron ore deposits worldwide, while the GIFs host smaller deposits in the Lake Superior region.

The commercial production of iron was begun by Jonas Tower in Large slag deposits at the smelter site still give evidence of the iron operation. Mining and smelting continued until the end of the 's when competition from the vastly larger and richer deposits in the Lake Superior region ended mining operations here.
The iron ore deposits on the peninsula quickly brought wealth to the area, and by the early 20th century, Marquette had already become a popular summer haven. Today, the city is surrounded by the natural beauty of Lake Superior's cliffs, beaches and forests.
