Sample No.: EET92001

Location: Elephant Moraine

Dimensions (cm): 20.5 x 11.0 x 9.0

Weight (g): 4015.6

Meteorite Type: Mesosiderite

Macroscopic Description: Cecilia Satterwhite

The largest inclusion visible on the exterior of this brown-colored mesosiderite is 4 x 2.8 centimeters. Regmaglypts and flow lines are visible on the few patches of fusion crust that have not weathered away. Minor fractures were noted on the exterior but do not penetrate through the interior of the meteorite. The interior is reddish-brown and fine-grained with abundant metal and silicate inclusions. The inclusions vary in size, shape, and color.

Thin Section (,7) Description: Brian Mason

The section shows a granular aggregate of approximately 40% nickel-iron, 40% pyroxene, and 20% plagioclase, with accessory merrillite and an SiO2 polymorph, probably tridymite. The grain size is relatively coarse, with individual pyroxenes and plagioclases up to 1 mm across. Many pyroxenes are partly or completely converted to a mosaic of small granules. Pyroxene compositions are somewhat variable, from Wo2Fs30 to Wo11 Fs28. Plagioclase composition is An90-92. The meteorite is a mesosiderite; it can be confidently paired with EET87500 and EET87501.
