The Meteoritical Bulletin, No. 101
Purchased: 2012 Feb
Mass: 372.6 g
Purchased by by Darryl Pitt and David Gheesling from a dealer in Zagora,
Morocco, in 2012 February.
characteristics: A single stone (372.6 g) lacking fusion
crust, exhibiting small feldspathic clasts in a darker matrix. One broadly
curved side of the stone is fairly fresh (but with beige weathering
products in fractures), whereas the other broken sides are coated with
Irving, S. Kuehner & N. Castle, UWS;
R. Mills, JSC).
Fine fragmental breccia composed of anorthite, olivine, augite, pigeonite
and orthopyroxene with accessory kamacite, ilmenite and troilite.
Olivine (Fa8.6; 25.7; FeO/MnO = 81-101), orthopyroxene (Fs23.3Wo4.6,
FeO/MnO = 69), pigeonite (Fs44.9Wo9.9, FeO/MnO = 54),
ferropigeonite (Fs82.2Wo15.8, FeO/MnO = 81),
subcalcic augite (Fs18.0-32.1Wo34.6-37.8, FeO/MnO =
47-58), plagioclase (An95.7-97.0Or0.1). Bulk
composition (R. Korotev, WUSL): mean
values from INAA of subsamples are 6.2 wt.% FeO, 11.8 ppm Sc, 310 ppm Ni,
10.5 ppm La, 4.8 ppm Sm, 0.94 ppm Eu, 3.5 ppm Yb, 1.9 ppm Th.
Lunar (feldspathic breccia).
Specimens: 20 g of
material is on deposit at UWB. The main
mass is owned jointly by D. Pitt and D. Gheesling.
