First mercury meteorite?

NWA 7325 is the name of a non-typical metor found in Morocco in 2012. Unusual mainly due to its greenish color and chemical composition, which suggests that this cosmic crust may come from the nearest Sun of our Solar System planet.

The cosmic rock consists of 35 debris, which in total weighs 345 grams. They were purchased by a meteorite dealer and then sent to Anthony Irving of Washington University who is an expert on the origins of extraterrestrial rock.

His interest has aroused the chemical composition of the rock. There was surprisingly little iron in the meteorite, while at the same time large amounts of magnesium, silicon and calcium. The composition was very similar to the Mercury rocks, which sent information to Earth about the Messenger probe – the first spacecraft to be sent to Mercury for investigation.

The exact composition of the meteorite does not exactly correspond to the rocks of the first planet from the sun, so Dr. Irving hypothesized that it could have come from deeper layers of the planet and was thrown into space by colliding the planet with another celestial body.

Dr Irving presented his findings at the 44th annual Lunar and Planetary Science conference in Texas. At the same time, pointing out that it is not one hundred percent of a place of rock origin. However, if the research was confirmed, it would be the first Mercuryan rock found on the surface of our planet.
