Macroscopic description

This is a platy-shaped nearly complete stone. 50% of stone is covered by shiny black fusion crust. Exposed interior shows fine-grained granular texture.

Petrographic Description

The section shows a typical poikilitic texture. Large oikocrysts of pyroxene enclose olivines and oxide minerals. Minor maskelynites are observed. Low-Ca pyroxene has a mean composition of Fs_22.0Wo_3.1. Olivine has a mean composition of Fa_33.0. Composition of maskelynite is An_61.2. The oxygen isotopic composition (analyzed by I. Franchi) of a bulk rock sample that is δ¹⁸O=4.178, δ¹⁷Ο=2.471, Δ¹⁷O=0.298, indicates that the meteorite is martian origin.
