1 Lunar Meteorites

Lunar meteorites are fragments of rock that were thrown off the Moon when it was struck by an impacting body, and then entered an Earth crossing orbit. These rocks survived entry through the Earth’s atmosphere in a fireball, and landed on Earth as a meteorite. All lunar meteorites are collected as finds (i.e., to date no one has actually witnessed a lunar meteorite fireball fall event) in hot and cold desert environments where they have been preserved by low levels of precipitation and excess terrestrial weathering, and are relatively easy to identify from the local terrestrial environment.

Most lunar meteorites have been found in Antarctica, Oman and in the deserts of North West Africa, and a few from deserts in Australia and Botswana. The first lunar meteorites Yamoto-791197 and Yamato-793169 were collected in Antarctica in 1979 by the Japanese meteorite hunting programme, although the first to be extensively studied as having a lunar origin was Allan Hills (ALHA) 81005, collected by the US meteorite hunting team in Antarctica in Jan. 1982. (n.b., meteorites are named after the closest named geographic feature or town).

To date, there have been ~177 individual (named) lunar meteorite stones collected on Earth. Collectively this represents ~67 kg of lunar material (~18% of the mass returned by the Apollo and Luna missions).

We know these samples are meteorites that came from the Moon using several lines of evidence (see here for more details): (i) a fusion crust initially identifies them as being a meteorite (this crust forms on the edge of a meteorite as it travels through the atmosphere); (ii) cosmogenic nuclide abundances and ratios (evidence of interaction with the space environment); and (iii) textural, chemical, mineralogical and isotopic similarity to Apollo and Luna samples  (see here for more details) distinguishes them from other meteorite classes.

My research focuses on studying the mineralogy, chemistry and chronology (age) of lunar meteorite samples to investigation the geological evolution of the Moon. Details of my lunar meteorite research papers can be found on my publication page.

2 Lunar Meteorites Resources

Randy Korotev’s Lunar Meteorite List is an excellent resource that keeps an up to date recent list and scientific references about lunar meteorites. More background about lunar meteorites can also be found here.

NASA’s Lunar Meteorite Compendium summarises the scientific findings of each stone.

3 Lunar Meteorites Notes

***************************
Statement regarding claims made by Mr Goran Lindfors: I studied a small fragment of material from Mr Lindfors. The data I collected demonstrated that the sample is texturally, mineralogically and chemically dissimilar to lunar materials and I relayed this information to him. I could not, therefore, support his attempts to seek to classify the sample as having lunar origin and I informed him of this. I understand that my name is now being used to support the sale of geological samples by Mr Lindfors that he is purporting as lunar meteorites. My testing did not support such a classification.
