Writeup from AMN 12(3):

Sample No.: EET87735

Location: Elephant Moraine

Dimensions (cm): 2x1.5x4

Field Number: 4691

Weight (g): 4.2

Meteorite Type: L3 chondrite

 

Macroscopic Description: Carol Schwarz

Fractured black fusion crust covers 90% of this unequilibrated chondrite. Numerous inclusions < 1mm in size are visible in the dark matrix.

 

Thin Section (,2) Description: Brian Mason

The section shows abundant chondrules and chondrule fragments, up to 1.8 mm across, in a black matrix containing some troilite and a little nickel-iron, which are concentrated as rims to the chondrules. A variety of chondrule types is present, including granular and porphyritic olivine and olivine-pyroxene, barred olivine, and fine-grained radiating pyroxene. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-25, mean Fa12 (CV FeO is 60); pyroxene, Fs2-22. The small amount of nickel-iron suggests L group, and the variability of olivine and pyroxene compositions type 3; hence the meteorite is classified as an L3 chondrite (estimated L3.4).
