On Offer: 3.465 gram lunar meteorite slice. The NEA 089 lunar meteorite is a rather rare subclass of lunar meteorite known as a "troctolitic anorthite melt breccia".
Description: An amazing 3.465 gram lunar feldspathic breccia meteorite full slice. This piece has been polished on one side, and offers an exceptional surface area to weight ratio. The classification of troctolitic anorthite melt breccia is based on the unmelted clasts contained within a mostly melted matrix, being composed of approximately 80% plagioclase (anorthite) and 20% olivine. According to the writeup, there was no pyroxene found in this lunar meteorite.
Official Name: Northeast Africa 089
Abbreviation: NEA 089
Type: Lunar (troct. anorth. melt breccia)
Dimensions: 58.59 mm x 39.48 mm x 0.99 mm
Year Found: 2024
Country: Libya
This meteorite was reportedly found by falconers in June 2024 near Lake Mukhayli in northeastern Libya and classified as lunar troctolitic anorthosite melt breccia, based on Fe/Mn values in olivine, high An values in plagioclase (anorthite), and modal composition of clasts.

Writeup from MB 115: Northeast Africa 089 (NEA 089) Libya Purchased: 2024 Classification: Lunar meteorite (troct. anorth. melt breccia) History: This rock was reportedly found by falconers in June 2024 near Lake Mukhayli in northeastern Libya and was bought later by Mr. Mohamed Lamin Muftah. Petrography: (K. Metzler, IfP) Achondritic melt breccia, consisting of lithic clasts (up to several cm) and mineral fragments (plagioclase, olivine), set in a fine-grained and vesicular crystallized melt. Clasts and melt are dominated by plagioclase, with smaller amounts of olivine. Point counting in a large clast revealed ~80% plagioclase and ~20% olivine). No pyroxene was found. Accessories are troilite and Ni-bearing metal. Geochemistry: Mineral compositions and geochemistry: Olivine Fa18.2±1.2 (Fa16.7-20.8); mean Fe/Mn (at.): 93.2; n=16. Plagioclase An97.6±0.6Or0.1±0.1 (An96.4-98.8Or0.0-0.4); n=15. Classification: Lunar troctolitic anorthosite melt breccia, based on Fe/Mn values in olivine, high An values in plagioclase, and modal composition of clasts. Specimens: The weight of the largest fragment is 12.9 kg. |
