hematit

hematit

An iron-oxide mineral (Fe₂O₃) that may be the cause of the red color on Mars. Courser-grained gray hematite has the same chemical formula as the red variety, but a different crystalline structure. The deposits of gray hematite found in the Terra Meridiani region of Mars may suggest that water once circulated through the region's rock layers.
