"Martian" meteorites (SNC and others)

Shergottite, Nakhlite, Chassignite, Orthopyroxenite, Augite Basalts, Basaltic Breccias

Norbert Brügge, Germany

Last update: 17.01.2019

The SNC-meteorites are a group of Achondrite meteorites, by them is assumed, that they originate from the Mars.
Shergottite meteorites are often made of mineral grains that can't be seen clearly without a microscope. 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 a mafic magma of the Earth.

Striking is the pronounced crystal growth in the groundmass, which is not comparable to the previously found flow basalts on the surface of Mars. Therefore, the origin of the material of this meteorites from Mars is more spectacular. It was supposed to have come directly from the mantle-sphere of Mars and had been explosively brought to the surface. The exceptionally young age of  some Shergottites (averaging 175 million years) proved that was still active volcanism on Mars at that time. It is possible that the material direct entered into space. The density of the Martian atmosphere at this time (Jurassic time on Earth) was already very similar to today's.

What tell us the presence of carbon in the shock-generated Martian meteorite "Tissint" about the genesis of Shergottite

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