The Dakota Sandstone is as much as 50 m thick and consists mostly of trough-crossbedded quartzarenitic sandstone.Inferred low-grade iron resources in the hematitic sandstone of the Rose Hill Formation of Middle Silurian age may total as much as 125 ft in beds 1-20 ft thick, interlayered with more than 100 ft of shale and nonhema­ titic sandstone. The hematitic beds locally contain 28 percent iron but average only 15 percent iron. TheyThe term ‘hematite’ itself might not be familiar to everyone, but its rusty red color definitely is. Sandstones are often reddish. This is because sand grains are coated with fine-grained hematitic powder. If soil is reddish, then it is also because of hematite. Even red granite owes its color to this mineral.The area has an estimated 340 million long tons of inferred low-grade iron resources in hematitic sandstone that may average as much as 20 percent iron, or 68 million long tons of contained iron.
