Found: 2007 Mar 2
Mass: 2.512 g
Found by a prospector on March 2, 2007, and subsequently purchased by
Norbert Classen at the Ensisheim Show in June 2011.
characteristics: A single black stone (2.512 g) devoid of
Irving and S. Kuehner, UWS).
Fine regolithic breccia composed of olivine, anorthite, augite, pigeonite,
ferropigeonite, hedenbergite (associated with Cr-armalcolite), silica
polymorph, fayalite, aluminous chromite, troilite and rare shred-like
kamacite grains. Portions of the matrix are glassy and contain tiny trapped
Olivine (Fa38.8-47.7, FeO/MnO = 86-106), pigeonite (Fs23.7-24.5Wo10.9-6.4,
FeO/MnO = 45), ferropigeonite (Fs52.5-56.5Wo24.7-18.9,
FeO/MnO = 62-64), plagioclase (An93.6-94.8Or0.1).
Bulk composition (R. Korotev, WUSL):
mean values from INAA of subsamples are 9.8 wt.% FeO, 24 ppm Sc, 320 ppm Ni,
8.1 ppm La, 3.7 ppm Sm, 0.75 ppm Eu, 3.2 ppm Yb, 1.7 ppm Th.
Lunar (mingled breccia). Although this stone is similar in bulk composition
to Dhofar 925, Dhofar 960 and Dhofar 961, it differs in appearance from those
stones and was found over 100 km away.
A total of 0.52 g of material is on deposit at UWB. Classen
holds the main mass.
