description Kalahari 009 Overview
Kalahari 009 is a lunar meteorite discovered in the Kalahari Desert of Botswana, Southern Africa. Classified as an anorthositic breccia, it is a piece of the Moon's crust that was ejected into space by an asteroid impact before falling to Earth. The meteorite is distinguished by its feldspar-rich mineralogy, which offers scientists insights into the geologic history of the Moon's highlands. It is a valuable specimen for planetary scientists studying the composition of lunar crustal rocks.
help Kalahari 009 FAQ
What makes Kalahari 009 a lunar meteorite?
Kalahari 009 is an anorthositic breccia made from material from the Moon's crust. Its mineralogy distinguishes it from ordinary terrestrial rocks and from Martian meteorites such as NWA 856.
How did a piece of the Moon reach Botswana?
An asteroid impact on the Moon launched crustal material into space, and one fragment eventually fell to Earth. Kalahari 009 was discovered in the Kalahari Desert of Botswana.
What does anorthositic breccia reveal about the lunar surface?
Anorthosite is strongly associated with the ancient lunar highlands, where light-colored feldspar-rich crust formed. The breccia texture shows that the material was broken and mixed by repeated impacts.
How is Kalahari 009 different from a lunar mare basalt?
Kalahari 009 represents anorthositic lunar crust rather than the dark basaltic lava that forms the lunar maria. It therefore provides a sample of the Moon's highland environment.
