A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020 [update] , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [ 1 ]
As of September 2020, 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [1] On 17 October 2013, NASA reported, based on analysis of argon in the Martian atmosphere by the Mars Curiosity rover , that certain meteorites found on Earth previously only thought to be from Mars ...
The elemental composition of Mars is different from Earth's in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle. [6] [7] The planet's distinctive red color is due to iron oxides on its surface. Second, its core is richer in sulphur. [8]
Analyzing the chemical composition of the meteorite’s 4.45 billion-year-old zircon grain — a mineral that is typically only a few millimeters in size and formed in rocks that have been altered ...
Allan Hills 84001 (ALH84001 [1]) is a fragment of a Martian meteorite that was found in the Allan Hills in Antarctica on December 27, 1984, by a team of American meteorite hunters from the ANSMET project. Like other members of the shergottite–nakhlite–chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars ...
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...

The only samples of Martian rocks that are on Earth are in the form of meteorites. The elemental and atmospheric composition along with planetary conditions is essential in knowing what minerals can be formed from these base parts.
