Hematite - NASA

Hematite is made up of iron and oxygen-a type of iron oxide. It takes its name from the Greek word for "blood," and is a rusty color in powdered form. Fine-grained hematite helps gives Mars its characteristic red hue. "Grey hematite is a mineral indicator of past water," says Crisp. "It is not always associated with water, but it often is."

Hematite - Wikipedia

Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a ...
