Lunar Meteorite (Feldspathic Breccia)

Physical Properties

Hardness: 6-7 (approximate); Color: Dark grey to black matrix with white/tan feldspathic clasts; Luster: Dull to sub-vitreous; Structure: Brecciated with fragmented crystals; Specific Gravity: 2.8 - 3.1

Formation & Geological History

Formed on the Moon's surface as regolith that was fused together by the heat and pressure of meteorite impacts. These are ejected from the Moon and eventually fall to Earth after space travel.

Uses & Applications

Predominantly used for scientific research to understand the Moon's geology, and highly valued for high-end geological collections.

Geological Facts

Lunar meteorites are rarer than diamonds on Earth. They are identified by their unique chemical markers, such as the ratio of manganese to iron, which differs from Earth rocks or meteorites from Mars.

Field Identification & Locations

Identify in the field by checking for a fusion crust (though often weathered away) and looking for distinct angular white clasts (Anorthosite) suspended in a dark, fine-grained matrix. Often found in hot or cold deserts (Sahara or Antarctica).
