Hematite: The mineral hematite information and pictures

Hematite is one of the most common minerals. 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 transformations of the mineral Limonite that lost water, possibly due to heat.
