NWA 10203 Meteorite Thin Section

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.

Tissint Meteorite Thin Section

The Tissint Meteorite was the first Martian witnessed fall since 1962. It is also special because the meteorite may contain carbon which has a biogenic origin. Under cross polarized light, thin sections of Tissint are a beautiful rainbow kaleidoscope of color in patterns similar to other Martian shergottites.
