The electrical properties of the water-saturated layer are obtained from laboratory measurements.The 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.

The first occurrence of pervasive green colouration is just below the MFc-MFbl contact, at a depth of312.8 m, where greenish sandstone occurs in bleached material adjacent to purplish hematitic sandstone, and in bands entirely within bleached, off-white intervals. NumerousInferred 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 remaining 20% consists mainly of pink hematitic crystallized tuff, a result of vapor-phase crystallization, and of tan and red ferruginous shale and siltstone. Discrimination of this unaltered tuff from the altered rocks may be possible in the 2.2 ..mu..m region because this absorption band is absent in the tuff spectra.In some areas the McNairy is limonitic (hydrous ferric oxide) or hematitic (ferric oxide) sandstone containing small amounts of titanium minerals such as rutile and ilmenite. Other Deposits Many of the sand and gravel deposits in Mississippian and Pennsylvanian rocks are weathered and of poor quality and have limited commercial use. SandstoneSandstone can be divided into three members: the basal Virgelle Sandstone Member which ranges in thickness from 80 to 130 ft (24-40 m) and the informally designated middle and upper members which together are as thick as 180 ft (60 m).
