meteorite: El Mihas: Weight 0.647 Grams: Rare Type Of Lunar. Anorthositic troctolite, similar to apollo 16. Mission samples, one of 11 ever!!!

SIMILAR TO APOLLO 16 MISSION SAMPLES!!!!!

This unique piece of history from space is a 0.601 gram part-slice of the rare El Milhas 007 meteorite, composed of lunar anorthositic troctolite. This is a very rare classification and gorgeous looking with yellow and grey/blue colors, 1 of 11 ever!!! This meteorite was recently discovered, and my newest classification, single stone find, supply is very limited. The slice is perfectly polished on one side and comes with a COA card and display case

Highly shocked, unbrecciated Lunar!!!!!

With its unique composition and rarity, this meteorite is a true treasure for any collection. Its significance lies not only in its extraterrestrial origin, but also in its potential scientific value. Own a piece of space history with this remarkable El Milhas 007 meteorite slice.

El Milhas 007 25.499269, -5.819294

Tiris Zemmour, Mauritania

Find: 2023

Classification: Lunar (anorth. troct.)

History: This meteorite was found by Sahrawi meteorite hunters in northern Mauritania, approximately 14 kilometers north of Chegga.

Physical characteristics: Single stone with a sandblasted exterior lacking fusion crust but showing numerous prominent regmaglypt pits. Surface coloration consists of patches of yellow-brown in most pit recesses, bounded by dark gray ridges. Inspection of a freshly broken surface from the deposit sample suggests that this meteorite is mostly unbrecciated. However, the presence of macroscopic shiny maskelynite indicates high shock stage.

Petrography: (C. Agee, UNM) This meteorite is an anorthositic troctolite with plagioclase (~70%), olivine (~25%), and clinopyroxene (~5%), and minor amounts of troilite, ilmenite, taenite, kamacite, and rare Fe-Ni sulfide. The olivine and pyroxene occur primarily as poikiloblastic inclusions within larger plagioclase grains consistent with an overall granulitic texture, however some domains have a relatively high olivine+pyroxene to plagioclase ratio which presumably corresponds to the macroscopic yellow-brown patches observed on the meteorite surface.

Geochemistry: (M. Spilde, UNM) Plagioclase An95.5±1.3Ab4.1±1.1, n=4; olivine Fa30.7±6.1, Fe/Mn=96±9, n=6; clinopyroxene Fs30.8±6.7Wo21.1±10.7, Fe/Mn=55±5, n=6.

Classification: Lunar (anorthositic troctolite) based on figure 1 in Stoeffler et al. (1980).

Specimens: 22 g on deposit at UNM, Matthew Stream holds the main mass.

SIMILAR TO APOLLO 16 MISSION SAMPLES

62237 and 62236 are chalky white rocks that were collected together along with 62235 and incidental soil, from the rim of Buster Crater, station 2, Apollo 16, where they were found half buried in the regolith (Sutton 1981). The mineral chemistry of these rocks is similar and indicates that they belong to the suite of lunar plutonic rocks termed ferroan anorthosite!

THE OLDEST MOON ROCKS!!!

Anorthosites, rocks composed almost entirely of plagioclase feldspar, are the oldest rocks on the Moon. They appear to have formed when feldspar crystallized and floated to the top of a global magma ocean that surrounded the Moon soon after it formed. Not all ages determined for anorthosites, however, are as old as we expected--one appeared to be only 4.29 billion years old. While 4.29 billion years sounds very ancient, a magma ocean ought to have solidified well within 100 million years of lunar origin about 4.55 billion years ago. One possibility is that the young ages reflect impact events, not the original time of igneous crystallization.
