The sample above is a cometary piece, was scanned on a color scanner and is enlarged (~1.5X) for clarity. The image you can see better below shows some mm inclusions/clasts (white arrows on the left), composed of shards, fragments, equigranular pieces of  sub-mm crystalline debris bound in an apparent amorphous powdery dusty drusy material and FeO and would have accreted with a frozen water-ice and other simple molecules in a very specific environment. The granular crystalline grains (sub-mm) accreted around the FROZEN FeO rich clasts in an incredibly intense environment, apparently outer stellar. The clasts are not amygdules nor vesicles which would have formed in a hydrothermal volcanic environment related to basalts or any metamorphic environment from Earth, and they may be Chondrules, CAIs, or some combination of the two, or they could be something totally different. We do not know yet.
