Sample No. LEW88201 Location: Lewis Cliff Dimensions (cm): 3 x 3.2 x 2.5 Field Number: 5693 Weight (g): 46.4 Meteorite Type: Ureilite
Macroscopic Description: Cecilia Satterwhite Shiny black and some frothy fusion crust covers this ureilite. One exterior surface has regmaglypts. The interior is bluish-black and has a crystalline texture. A small amount of evaporite deposit is present.
Thin Section (,2) Description: Brian Mason This 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 show olivine and pyroxene of uniform composition: olivine, Fa8 (CaO 0.3%); pyroxene, Wo5Fs8. The meteorite is a ureilite; it is very similar in texture and mineral compositions to LEW 85440 and 88012, and the possibility of pairing should be considered.
