These photos were taken of four thin sections that were deaccessioned by a US university. They appear to have been made by different people and at different times. On one, the cover slip cement has turned yellow. Some have labeling engraved on the slide behind the sample. Some of this can be attributed to the sample size being very large, covering most of the slide. Some samples have been polished a bit thinner than the standard 0.03mm. This might have been intentional since it helps reveal structures that are otherwise obscured by the fine grained matrix of this type 3 carbonaceous chondrite.
The layers in these chondrules distinguish themselves by differences in texture and composition. And these result from successive episodes of accretion and heating. Layers tend to be finer grained toward the outside of chondrules. We see different types of cores.
