| Title | Hematite of Ruth Slate Formation |
|---|---|
| Description | Hematite is a form of iron oxide, Fe2O3, containing about 70% metal. It occurs in nature as red to brown to orange masses and coatings, and in metallic to semimetallic steel-gray to black crystalline forms. Hematite that has a metallic luster is called specular hematite. Red powdered hematite is used as a pigment (ocher) and as rouge in polishing. Hematite is an important ore of iron. Extensive and richly productive deposits occur in the Lake Superior region (Michigan, Minnesota, and Wisconsin) and the Birmingham district (Alabama). The mineral is widely distributed throughout the world and is responsible for the red coloration of many sedimentary rocks. |
