Note the saw tooth appearance of the grains in all images. Image 3 exhibits what appears to be the "carbonaceous-metal-silicate" material described in the Meteoritical Bulletin Database for this meteorite and its pairing with NWA 2624.

Image 1 - imaged in transmitted white light with crossed polars; no accessory plates - high birefringence exhibited by the olivine grains.

Image 2 - imaged in transmitted white light with one polar.

Image 3 - imaged in transmitted and raking reflected white light; both with one polar.
