Andy writes:
A new, yet to be classified brecciated LL6 ordinary chondrite found on the Nullarbor Plain in April this year, during the annual Monash University expedition.

The name is a field ID - the date it was found, and the letter C indicates that it's the 3rd meteorite we found that day. Some days we're lucky and we get down to letter J.

The meteorite was about as easy to spot as they come; distinctly darker than the surrounding pale limestone gibber on the surface of the Nullarbor. The two thin section photographs show the fine-scale affects of shock - the black inclusion trails are troilite-metal particles in healed fractures in olivine. These inclusions represent what is known as shock blackening - the numerous opaque inclusions block the passage of light, making the sample appear darker.
