This thin section of NWA 10203 shows a wide range of fascinating features. As described on the Meteoritical Bulletin, this lunar breccia contains four lithologies:
1. Unbrecciated olivine gabbro with zoned clinopyroxene.
2. Fragmental anorthositic gabbro breccia.
3. Fragmental gabbroic breccia with approximately equal proportions of plagioclase, pyroxene and olivine.
4. Shock melt veins and pools.
There appears to be a least two of these lithologies in this specimen.
