Writeup from AMN 13(3):
Sample No. LEW88281 Location: Lewis Cliff Dimensions (cm): 3 x 2 x 1 Field Number: 6037 Weight (g): 9.7 Meteorite Type: Ureilite
Macroscopic Description: Cecilia Satterwhite Some thin polished fusion crust remains on the exterior of this ureilite. The interior is bluish-black in color, crystal faces are easily noticed and oxidation is moderate.
Thin Section (,2) Description: Brian Mason The section shows an equigranular aggregate of olivine and pyroxene, as rounded to subhedral grains 0.3-0.6 mm across. The grains are rimmed with black carbonaceous material, which contains trace amounts of nickel-iron (largely weathered to brown limonite) and troilite. Microprobe analyses give the following compositions: olivine, Fa9; pyroxene, Wo5Fs8. The meteorite is a ureilite; it is very similar in texture and mineral compositions to LEW 85440, 88012, and 88201, with which it is probably paired. | ||||||||||||||||||||||||
