Hematite

Hematite

Named for the Greek word aimatodes, meaning “bloodlike,” in reference to the mineral’s color and streak. Hematite is extremely common with thousands of localities with exceptional crystals from Switzerland, Romania, Italy, England, Norway, Brazil, South Africa, Algeria, and the United States. Hematite occurs as an accessory mineral in igneous rocks, as a sublimate in volcanic rocks, in high-temperature hydrothermal veins, a contact metamorphism product, in metamorphosed banded iron formations, as a cement in sedimentary and a constituent in oolitic iron formations, and it is abundant on weathered iron-bearing minerals.

Hematite from Cornwall Iron mine, Lebanon Co., Pennsylvania, United States

Hematite
            from Cornwall Iron mine, Lebanon Co., Pennsylvania, United States

Mass of specular Hematite. 

The Cornwall Iron Mine was discovered in 1739 and boasted the largest iron deposit east of the Mesabi and Lake Superior deposits. The mines were important to the revolutionary war efforts. Although preserved up to the 1970's, the historic ruins were eventually demolished. More history can be found on the Abandoned America website.

Hematite from Soudan mine, Vermilion Range, St. Louis Co., Minnesota, United States

Hematite
            from Soudan mine, Vermilion Range, St. Louis Co., Minnesota, United States

Drill core from this historic iron mine discovered in the 1880's which eventually reached a depth of 2,300 feet in underground workings and operated by US Steel. The mine is located in the Vermillion range and the ore was extracted from the 2.7 BYA Archean Soudan Iron Formation of the Ely Greenstone Belt. It is no longer in operation. It is now nicely preserved as a Minnesota State Park and is also home to an undergrond laboratory for the collection of neutrinos.
