Sample No.: EET87532 Location: Elephant Moraine Weight (g): 193.5 Field No.: 2631 Dimensions (cm): 9 x 4 x 4 Meteorite Type: Polymict Eucrite
Macroscopic Description: René Martinez This eucrite is heavily weathered. A few dark fine-grained clasts are visible up to about 1 cm across. One coarse-grained monomineralic inclusion is about 2 cm in length. The matrix is fine-grained and dark-gray with a 0.5 cm thick weathering rind.
Thin Section (,8) Description: Brian Mason The section shows a microbreccia, consisting largely of angular monomineralic pyroxene and plagioclase clasts up to 1.2 cm in maximum dimension, and a few lithic clasts, in a matrix of comminuted pyroxene and plagioclase. Clasts show basaltic to subophitic texture, except for one (6 mm across), which consists of large (up to 2.5 mm) rounded subhedral pyroxene (Wo7Fs33) grains in turbid brown glass. Microprobe analyses show pyroxene of variable composition: Wo2-40, Fs33-55, En 14-60; plagioclase is An91-93. The meteorite is a polymict eucrite. | ||||||||||||||||||||||||
