Lunar meteorite (feldspathic breccia)
Purportedly found near Boujdour and purchased in Agadir, Morocco, by Adam Aaronson in September 2013.
characteristics: A single stone (98 g) broken into
three pieces that fit together. Small white clasts are visible in a dark
(A. Irving and S. Kuehner, UWS) Breccia consisting
of numerous mineral fragments and rare ophitic-textured, basalt clasts in a
finer grained matrix. Minerals are anorthite, olivine, unexsolved
pigeonite, subcalcic augite, augite, exsolved pigeonite, ilmenite, Ti-rich
chromite, troilite, and rare kamacite and barite. Sparse clasts composed of
intergrown fayalite+hedenbergite+silica polymorph
Olivine (Fa19.8-38.8, FeO/MnO = 86-105), pigeonite (Fs47.0Wo19.6,
FeO/MnO = 59), subcalcic augite (Fs39.9Wo33.2, FeO/MnO
= 58), augite (Fs52.0Wo41.9, FeO/MnO = 74). Bulk
composition (R. Korotev, WUSL) INAA of
subsamples gave (in wt.%) FeO 5.9, Na2O 0.42, and (in ppm) Sc
14.8, La 1.9, Sm 0.98, Eu 0.93, Yb 1.0, Th 0.2.
Lunar (feldspathic fragmental breccia).
Specimens: 19.6 g
(including a polished end-cut specimen and a polished mount) are at UWB. The remainder
