Lunar Feldspathic Breccia

Physical Properties

Hardness: 6-7 (Mohs scale), Color: Dark grey to black matrix with white/tan light-colored clasts (anorthosite), Luster: Dull to sub-vitreous, Structure: Brecciated fine-grained matrix with angular inclusions.

Formation & Geological History

Formed on the Earth's Moon via multiple impact events that shattered and fused lunar crustal rocks. These rocks were eventually ejected from the lunar surface by a large asteroid impact and fell to Earth as meteorites.

Uses & Applications

High scientific value for planetary research; highly sought after by private collectors and museums.

Geological Facts

Lunar meteorites are rarer than gold or diamonds. They allow scientists to study the composition of the lunar highlands across the Moon, beyond just the Apollo landing sites.

Field Identification & Locations

Identify by its unique fusion crust (if present), absence of quartz, and presence of light-colored plagioclase-rich clasts in a dark, shock-melted matrix. Most are found in arid environments like the Sahara or Antarctica.
