NWA 16200 來自月球的精美而稀有的作品 無粒隕石 - 4157 g - (1)
Weighing 4157 grams and boasting exceptional freshness, this lunar meteorite fragment stands unparalleled. It originates from the Moon, ejected off its surface by asteroid impact and eventually landing on Earth. While similar to lunar samples brought back by Apollo astronauts, those are property of the United States Government, under NASA's control at the Johnson Center and Smithsonian Institution. Lunar meteorites represent less than 0.5% of all recovered meteorites.
Distinctive geological, mineralogical, chemical, and radiation signatures identify lunar specimens, with many minerals rare on Earth but abundant on the Moon. This particular piece, NWA 16200, is one of 28 approved meteorites classified as Lunar (melt breccia), discovered and categorized in Northwest Africa. Recorded in the Meteoritical Bulletin, it epitomizes a lunar melt breccia rock amalgamated by interstitial impact melt retaining its pristine condition without terrestrialization from exposure to Earth's elements.
This specimen showcases the coveted contrast between the ground mass and white anorthosite, the Moon's oldest rocks.
