Minerals

Minerals are natural resources needed as raw material for setup and extension of settlements on Mars. From recent unmanned missions some valuable minerals have been found, most of them by the Mössbauer spectrometer MIMOS II.

Goethite

Chemical formula: α-FeO(OH)

This mineral has been identified near the touch down place of the rovers Spirit and Opportunity, for example at "Columbia Hills". This mineral was probably created from iron under the influence of liquid water.

Hematite

Chemical formula: α-Fe₂O₃

This mineral has been found at the touch down place of Opportunity.

Olivine

Chemical formula: (Mg,Fe)₂SiO₄

This mineral has been found in Gusev Crater.
