The specimen displays the characteristic light-toned feldspathic matrix that defines lunar highland material, formed over 4 billion years ago during the Moon's early differentiation. As a full slice rather than a fragment, this piece shows the complete cross-section of the meteorite's internal structure, providing clear visibility of the brecciated texture throughout.\u003c\/p\u003e\n\u003cp\u003eRabt Sbayta 007 was recovered in Western Sahara in 2017 and classified as a feldspathic breccia, placing it among the lunar meteorites that sample the Moon's ancient anorthositic crust. The slice format preserves both natural exterior and interior features, offering a comprehensive view of lunar highland geology in a compact, display-ready format.\u003c\/p\u003e\n\n\u003ch2\u003eFeldspathic breccia structure\u003c\/h2\u003e\n\u003cp\u003eThe slice reveals the fragmental nature of lunar highland breccias, consisting of angular clasts of anorthosite and related feldspathic lithologies cemented together by impact processes. Feldspathic breccias form when meteoroid impacts on the Moon's surface shatter and mix highland crustal rocks, then lithify the debris through shock compression and localized melting. The light coloration results from the dominance of plagioclase feldspar, the primary mineral in the lunar highlands.\u003c\/p\u003e\n\u003cp\u003eMicroscopic examination of feldspathic breccias reveals multiple generations of impact processing, with clasts containing earlier brecciation events embedded within younger breccia matrices. This layered history records billions of years of bombardment on the airless lunar surface, where every impact contributes to the ongoing recycling of crustal material.\u003c\/p\u003e\n\n\u003ch2\u003eScientific context\u003c\/h2\u003e\n\u003cp\u003eLunar meteorites originate from the Moon's surface, ejected into space by large asteroid impacts with sufficient energy to overcome lunar gravity. These specimens drift through space until Earth's gravity captures them, delivering samples from regions of the Moon not visited by Apollo or Luna missions. Feldspathic breccias specifically sample the lunar highlands, the light-colored, heavily cratered terrain visible from Earth that contrasts with the darker volcanic maria.\u003c\/p\u003e\n\u003cp\u003eThe lunar highlands represent the Moon's primordial crust, formed when plagioclase feldspar floated to the top of the lunar magma ocean approximately 4.4 billion years ago. This anorthositic material dominates the Moon's far side and much of the near side highlands, making feldspathic meteorites critical for understanding the Moon's early differentiation and subsequent impact history. \u003ca href=\"\/pages\/learn-about-meteorites\"\u003eLearn About Meteorites\u003c\/a\u003e to understand how these specimens reach Earth and why they matter for planetary science.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIs this meteorite authenticated?\u003c\/strong\u003e Rabt Sbayta 007 is officially classified in the Meteoritical Bulletin as a lunar feldspathic breccia. The classification confirms lunar origin through oxygen isotope analysis, mineral chemistry, and petrographic examination.

In lunar meteorites, this classification indicates material from the Moon's ancient highland crust, where plagioclase feldspar dominates the mineralogy. The brecciated texture results from repeated meteoroid impacts that shattered and mixed crustal rocks over billions of years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is included with this specimen?\u003c\/strong\u003e This listing includes the 1.44g lunar meteorite slice, certificate of authenticity, specimen card with classification details, and display box for protection and presentation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do we know this came from the Moon?\u003c\/strong\u003e Lunar origin is confirmed through multiple analytical techniques: oxygen isotope ratios that match Apollo samples, mineral compositions consistent with lunar formation conditions, and the presence of diagnostic lunar minerals. The feldspathic composition, low iron content, and absence of water-bearing minerals all align with known lunar geology, providing definitive evidence of Moon origin.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan feldspathic breccias tell us which part of the Moon they came from?\u003c\/strong\u003e Unlike mare basalts that have distinctive ages and compositions, feldspathic breccias sample the broadly similar highland crust and cannot be traced to specific impact craters or regions. However, their composition confirms they originate from the ancient anorthositic crust that dominates the lunar highlands, providing samples from regions potentially inaccessible to spacecraft missions.\u003c\/p\u003e\n\n\u003ch2\u003eCollector significance\u003c\/h2\u003e\n\u003cp\u003eLunar meteorites remain among the most sought-after specimens in meteorite collecting, offering private ownership of material from another world.
