The SNC-meteorites are a group of Achondrite meteorites, by them is assumed, that they originate from the Mars. They own an in comparison with other meteorite low old (about a billion years) and must originate thus from a celestial object, which had still a relatively young geological activity. Besides they includes gases, which correspond to in their composition of the Mars-atmosphere, as they are determined also by measurements of the Viking-probes.

SNC-Meteorites are often made of small mineral grains that can't be seen clearly without a microscope. To see these small grains, scientists grind and polish rock samples very thin (0.03 millimeters) so light can pass through them. This picture is a microscopic view, about 2.3 millimeters across, of a martian meteorite. The brown areas are grains of the mineral pyroxene and the clear white areas are the mineral plagioclase. These are the two most abundant minerals in basalt, both on Earth and Mars. The black areas are magnetite, an iron-oxide mineral.

The following meteorites are identified as stones from Mars
(compare:  Météorites martiennes  and  imca: List of Martian Meteorites
