Glacially eroded outcrop of jaspilite banded iron formation in the Precambrian of Minnesota.
The Soudan Iron-Formation is a Neoarchean-aged banded iron formation (BIF) unit in the Vermilion Greenstone Belt of northeastern Minnesota, USA. Stratigraphically, the Soudan is considered to be the middle member of the Ely Greenstone. Metamorphosed pillow basalt successions occur above and below the iron-rich interval:
- upper member of the Ely Greenstone
- Soudan Iron-Formation member
- lower member of the Ely Greenstone
Radiometric dating of Ely Greenstone rocks (see Jahn & Murthy, 1975 and Jirsa et al., 2010) indicates that the Soudan Iron-Formation is about 2.722 billion years old.
The Soudan Iron-Formation was deposited in a deep-water environment and is closely associated with several types of volcanic rocks formed in an ancient island arc setting. As such, the unit is classified as an Algoma-type iron-formation. Superior-type iron-formations were deposited in relatively shallow water, continental shelf settings.
The Soudan Iron-Formation is exposed in & around the town of Soudan, Minnesota at roadcuts, glacially-eroded outcrop knobs, surface mines, and underground mines. The best exposures are at Soudan Underground Mine State Park. The Soudan Mine targeted high-grade iron ore (specularite) for many decades and closed in the early 1960s. The site is now accessible to the public and underground tours are offered.
Observed iron-rich lithologies in the Soudan Iron-Formation include specularite, jaspilite BIF, and magnetite BIF.
The above photo is part of a glaciated knob of jaspilite BIF in Soudan Mine Park. The outcrop is glacially smoothed and striated. The rocks here are faulted and complexly folded. Folding occurred in two phases - some of it occurred during soft-sediment deformation events and subsequent structural folding occurred after the rocks were lithified. The light-colored layers are chert (= microcrystalline to cryptocrystalline quartzose sedimentary rock), the red layers are "jasper" (= hematite-rich chert), and the silvery-gray layers are magnetite-chert. A detailed description of this outcrop occurs in Huda et al. (2008).
Stratigraphy: Soudan Iron-Formation member, Ely Greenstone, Vermilion Greenstone Belt, Neoarchean, ~2.722 Ga
Locality: glaciated outcrop knob adjacent to Stuntz Bay Road in Soudan Underground State Park, Soudan, northern St. Louis County, northeastern Minnesota, USA (47° 49' 14.82" North, 92° 14' 11.84" West)

This is the scenery to the west as you drive north on US 89 from the north rim of the Grand Canyon to the south rim.
The formations remind me of an old 1950's science fiction movie where the rock come to life and start walking.

In my backyard one day, late morning into the afternoon I looked up and saw these beautiful clouds in the sky with the sun shining through. I thought WOW, this is gorgeous and started shooting. These are the images I was fortunate to obtain! Photo images credited to Vickie L Klinkhammer of Vickielynne Photography and Designs (VLP&Designs).
