Hematitic sandstone
The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Non-crystalline forms of Hematite may be transformation s of the mineral Limonite that lost water, possibly due to heat. Chemical Formula. Fe2O3.Mauch Chunk Formation (Mississippian) at surface, covers 3 % of this area. Grayish-red shale, siltstone, sandstone, and some conglomerate; some local nonred zones. Includes Loyalhanna Member (crossbedded, sandy limestone) at base in south-central and southwestern Pennsylvania; also includes Greenbrier Limestone Member, and Wymps Gap and Deer Valley Limestones, which are tongues of the Greenbrier.

Hematitic sand and sandstones are mainly consisting of quartz but these quartz grains have an intense pink, orange or red color. The coloring agent in this sand is volumetrically insignificant – it is hematite (oxide of iron) that forms very thin rust-colored pigment on larger silicate grains.
