Abundance and usage

Abundance

Elemental abundance in the solar system. Wikicommons.

exact abundance of minerals in the Martian crust are not know precisely. The abundances for Earth are used for the moment^[1].

Production and Usage

Mineral and metal extraction and production will require large amounts of energy. Depending on the Martian population and the Settlement construction methods, production rates may be higher than those on Earth.

Although almost most elements on Mars are found in compounds or minerals, and mostly oxides or chlorides or fluorides, some elements may be found in elemental form such as inert gases

Neon and argon may be used a buffer gases in the atmosphere of Martian settlements, or as propellants for Ion engines.
