NWA 5903 Meteorite Thin Section

This thin section image of NWA 5903 provides viewers with an abstract painting created by nature. To look at a thin section of any rock under cross polarized light is to view the emergent features of mineral formation. Sextillions upon sextillions of atoms all interacting! It is fascinating to observe how matter crystallizes in various geometries and how this crystallized matter acts under polarized radiation. The eucrites are always wonderful to view this natural process, and NWA 5903 does not disappoint. The calcic plagioclase and exsolved pyroxene are mostly what give this image its incredible beauty.

NWA 11220 Meteorite Thin Section

What a fascinating meteorite! NWA 11220, just like the previously posted NWA 8171, is a Martian Basaltic Breccia. It shares many of the same characteristics and the clasts have similar appearances. In the thin section posted here, readers can explore some eerily “alien” features which seem unique to this particular class of Martian meteorites. The large inclusion on the left side of the thin section contains fascinating little globular specks. Additional clasts contain shapes and features which pose numerous questions, such as what kind of “natural” processes could have formed them? Enjoy!

NWA 10690 Meteorite Thin Section

This thin section of NWA 10690 gives a unique view of the transformations and processes occurring in ancient times. Within the large grains of similar color can be found smaller grains of various colors, shapes, and sizes which imply internal changes occurring within the source body. Paired with NWA 7030, it belongs to the LL7 class of meteorites, contains sanidine (on Earth found in felsic volcanic rocks like obsidian), and gives the impression of being a fascinating sample from the early solar system.
