Sample No.: EET90628

Location: Elephant Moraine

Field Number: 7182

Dimensions (cm): 2.5 x 2 x 1.5

Weight (g): 23.0

Meteorite Type: L3 chondrite

Macroscopic Description: Cecilia Satterwhite

The exterior surface of this chondrite is covered with shiny fractured black fusion crust. A bluish colored evaporite deposit is pervasive. The interior is chock-full of inclusions/chondrules. Most of the chondrules have well-defined edges. A 3 mm sized clast was noted. Matrix is dark gray.

Thin Section (,2) Description: Brian Mason

The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 2.4 mm across, in a dark matrix containing small mineral grains and a little nickel-iron and troilite. Minor weathering is indicated by some brown limonitic staining, mostly in association with the metal grains. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-20, mean Fa11 (CV FeO is 48); pyroxene, Fs1-19. 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 L3.5).
