Moon Meteorite Slice NEA 089 – Lunar Breccia, 4.21 g

This moon meteorite slice is a sliced fragment of the Northeast Africa 089 (NEA 089) lunar meteorite, found in northeastern Libya. The stone has been cut into a slice for display and study purposes, revealing its internal brecciated structure. It represents authentic lunar material that was ejected from the Moon by impact processes and later delivered to Earth.

NEA 089 is a particularly interesting lunar meteorite due to its specific classification as a troctolitic anorthosite melt breccia, a distinctive type of lunar impact breccia. The meteorite was officially classified as lunar material by the Meteoritical Bulletin in March 2026.

Scientific and Physical Characteristics

NEA 089 is an achondritic melt breccia composed of lithic clasts and mineral fragments embedded in a fine-grained, vesicular crystallized melt. The clasts can reach several centimeters in size and are dominated by plagioclase with smaller amounts of olivine.

A large analyzed clast consists of approximately 80% plagioclase and 20% olivine. No pyroxene was identified in the analyzed material. Accessory phases include troilite and nickel-bearing metal.

The mineral chemistry provides important evidence for the lunar origin of NEA 089. Olivine has a measured fayalite content of approximately Fa18.2, while the plagioclase is highly calcic, with compositions around An97.6. These mineral compositions, together with the modal composition of the clasts, were used to classify the meteorite as a lunar troctolitic anorthosite melt breccia.

The melt-breccia texture records the effects of impact processes on the lunar surface. Fragmented lunar crustal material was incorporated into impact-generated melt and subsequently crystallized, preserving a complex mixture of mineral fragments and lithic clasts within the meteorite.

The meteorite was reportedly found by falconers in June 2024 near Lake Mukhayli in northeastern Libya. The material was subsequently purchased by Mohamed Lamin Muftah. The total officially recorded mass is 16 kg, distributed among several pieces, with the largest individual fragment weighing 12.9 kg.

This cut moon meteorite slice provides an opportunity to examine the internal structure and mineralogical character of this recently classified lunar meteorite.
