Purchased: 2012 Feb
Mass: 372.6 g
meteorite (feldspathic breccia)
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
(A. 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.
