Sample No.: EET90080; 90161; 90261

Location: Elephant Moraine

Field Number: 7336; 6675; 7313

Dimensions (cm): 1.5 x 1.5 x 0.8; 2 x 1.7 x 0.9; 2 x 1.7 x 0.6

Weight (g): 4.1; 9.7; 6.6

Meteorite Type: L3 chondrite

Macroscopic Description: Cecilia Satterwhite

Black, pitted, and fractured fusion crust covers most of EET90080 and 90261 and half of 90161. The interiors of all three stones are black with abundant light and dark colored chondrules/inclusions. Many of the chondrules have well-defined edges. Evaporite deposit is present on 90261.

Thin Section (EET90080.2) Description; Brian Mason

EET90161,2 and 90261,2 are similar in all respects, and are probably paired with EET90080. The section of EET90080 shows a close-packed aggregate of chondrules and chondrule fragments, up to 1.5 mm across, in a dark matrix which contains a little nickel-iron and troilite. Minor weathering is indicated by a limited amount of brown limonitic staining throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa 1-22, mean Fa12 (CV FeO is 60); pyroxene, Fs1-27. The variability of olivine and pyroxene compositions indicates type 3, and the small amount of nickel-iron L group, hence the meteorite is classified as an L3 chondrite (estimated L3.4).
