Writeup from AMN 15(2):
Sample No.: EET90098 Location: Elephant Moraine Field Number: 6994 Dimensions (cm): 1.5 x 1.7 x 1.2 Weight (g): 4.7 Meteorite Type: L3 chondrite
Macroscopic Description: Cecilia Satterwhite Three-quarters of the exterior of this unequilibrated chondrite is covered with weathered fusion crust. Abundant chondrules are visible in the weathered brown matrix. Some metal was noted.
Thin Section (,2) Description: Brian Mason The section shows numerous chondrules and chondrule fragments, up to 1.9 mm across, in a granular matrix of olivine and pyroxene with a little nickel-iron and troilite. Considerable weathering is indicated by brown limonitic staining throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa5-27 , mean Fa21 (CV FeO is 28); pyroxene, Fs4-19. 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 L3.7).
