It reminds me of some iridescent colorings I've seen on some weathered iron oxides. I've seen it in rock specimens which were weathering out of veins which contain gold, various Fe oxides and Mn oxides. I can't think of any mineral names (maybe Goethite). A geologist would know - I can't imagine why it wouldn't be seen in meteorites - like when a piece of iron is coming through the crust. I can't say for sure, but I bet I've seen it in weathered Holbrook meteorites or SAU001. That's no guarantee it is the same stuff, but it's similar in appearance. I hope that helps.
But for sure it definitely doesn't look like the blue chondrule that was shared the other day if that's the inclusion you're talking about. It's very interesting for sure! Mark B.

The streaks on my primary specimen with the markings, and others that I have seen, are not as DARK vivid blue as your inclusion appears to be, but the streaks do have somewhat of an iridescent look to them as well. Anyone have any thoughts on this? Like I said, I may be way off, but hopefully some member(s) will be able to shed more light on the topic, as we approach the one year anniversary of the fall.
