Iron County’s bedrock is dominated by a 35 km. thick sequence of Precambrian rocks tilted steeply by thrusting along the Marenisco Fault. These Precambrian rocks occur in NE striking belts, with the oldest at the southern edge of the county. These oldest rocks in the section are poorly exposed Archean meta-volcanic and meta-sedimentary rocks. These are overlain by a thick section of Proterozoic sedimentary rocks, including the Ironwood Iron Formation, which was the main formation extensively mined in the Gogebic Iron Range. These are overlain by a thick section of 1.1 billion year old (Keweenawan) volcanic rocks (Powder Mill Group and Portage Lake Lava Series) from the Mid-Continent Rift. These are intruded by the complexly differentiated Keweenawan–age plutons of the Mellen Complex. On top of these is a package of Proterozoic sedimentary rocks (Oronto Group) which further filled the rift after the cessation of volcanism. The youngest bedrock, separated from the older rocks by another large thrust fault, the Douglas Fault, is the little metamorphosed Proterozoic Bayfield Group sandstones.
The Keweenawan volcanic rocks are locally quarried for road metal. The Ironwood Iron Formation hosted some important mines, notably the Montreal and Cary mines, which produced world class specimens of goethite, hematite, manganite, manganocalcite, barite and other minerals. These were underground mines, which worked the oxidized zones in the iron formation down dip to depths of over 4,000 feet. The mines closed in the 1960's, but there has been renewed exploration in the area (2013).
Glacial drift and glacial lake sediments cover a lot of the county. The coarse tills and outwash can yield interesting minerals such as “drift” copper and Lake Superior agates.
