Sample No.: EET83247 Field No.: 2711 Location: Elephant Moraine Weight (g): 22.5 Dimensions (cm): 4 x 2.5 x 1.5 Meteorite Type: Aubrite (?)
Macroscopic Description: Roberta Score Shiny black fusion crust covers approximately one quarter of EET83247. Half of the exterior surfaces have weathered to a reddish-brown. Half is medium gray with large cream-colored clasts. One fine-grained black clast was noted. Most of the exposed interior has been heavily oxidized.
Thin Section (,4) Description: Jeremy Delaney This is texturally similar to ALH83015 and contains lithic fragments with both pyroxene and olivine. Pyroxene composition is En72Wo2.5 and is, therefore, different from the Elephant Moraine 79002 diogenite which contains En76Wo2. [From AMN 8(2):] RECLASSIFICATION OF EET83247 AS A DIOGENITE Meteorite EET83247 was listed in the previous Newsletter issue (8(1), p. 31) as an "aubrite (?)" However, a mistake in the classification report was not discovered until after the Newsletter was mailed. Be advised that EET83247 is a diogenite. | ||||||||||||||||||||||||
