Michigan Iron Mines

2016-2-26  Iron ore production in Michigan had a humble beginning. Prior to 1840, bog ore found in swamps was used in charcoal furnaces to produce pig iron. This iron ore was of low grade and deposits were small, thus limiting the size and advance of the industry. It was not until discovery of the iron formations in 1844,

2021-1-21  Iron ore was first "discovered" by European settlers when the early land surveyor, William Austin Burt, was shown iron ore by an Indian chieftain near what is now Negaunee, Michigan, in 1844. He had noticed a strange movement of his compass needle while surveying near where the present town of Ishpeming is located.

Hard iron ore of the Marquette Range, Michigan

Hard iron ore on the Marquette Range consists of nearly pure masses of specularite, magnetite, or martite and occurs near the unconformable contact of the Negaunee Iron-Formation with the overlying Goodrich Quartzite. Most ore is in an upper jaspilite unit of the Negaunee, but some orebodies are entirely within the basal part of the Good-rich ...

Multiple episodes of hematite mineralization indicated by ...

Monazite in iron-ore deposits within the hinges of Penokean-aged folds yields an age of ca. 1.8 Ga, which is interpreted to record a second phase of hematite enrichment. Monazite and xenotime in iron-ore deposits along the limbs of regional folds give ages of ca. 1.77 Ga and are interpreted to record a later episode of hematite upgrading.

Newport Iron Mine In Ironwood, Michigan The Diggings™

Ironwood, Michigan. The Newport Iron Mine is in Ironwood, Michigan. Historically the site has been associated with the Michigan Gogebic Iron Mining District which is now part of the Ottawa National Forest. The site was first discovered in 1848 by A. Randall. The Newport Iron Mine was closed at the time of data entry with no known plans to re-open.
