Name: Elephant Moraine 90916 This is an OFFICIAL meteorite name. Abbreviation: EET 90916 Observed fall: No Year found: 1990 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 4.6 g
Sample No.: EET90909; 90916 Location: Elephant Moraine Dimensions (cm): 1.7 x 1.4 x 1.2; 2.2 x 1.3 x 1.2 Weight (g): 6.4; 4.6 Meteorite Type: L3 chondrite (estimated L3.6)
Macroscopic Description: Cecilia Satterwhite Black fusion crust covers ninety percent of each of these specimens. Oxidation haloes are present in the fusion crust of 90909. The interior of both specimens is dark brown to black with areas of extensive oxidation. Light and dark inclusions are abundant and range in size from 1 mm to 3 mm.
Thin Section (EET90909,2; 90916,2) Description: Brian Mason The sections are so similar that a single description suffices; the meteorites are probably paired. Chondrules and chondrule fragments, up to 2.9 mm across, are abundant, and are set in a black matrix which contains a little nickel-iron and troilite. Considerable weathering is indicated by brown limonitic staining throughout the sections. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-22, mean Fa12: pyroxene, Fs2-23. The meteorites are classified as L3 chondrites (estimated L3.6).
