TKW 2 tons. Observed fall 8 February 1969, at the village of Pueblito de Allende, Chihuahua, Mexico.

Famously fell during the early part of the Apollo programme and swiftly and significantly increased the worlds stock of carbonaceous material. I take great delight in telling people that the white CAIs may well be the oldest things that they will ever touch or see (with the naked eye and in visible wavelengths, at least), but Id noticed the small gold-coloured inclusions so asked my brother (a far better photographer than I am) to use a macro setup and try to get some photos that better showed this feature. Were guessing its iron pyrite (FeS2), but I suspect many here are rather better qualified than us to judge.

Thanks, all - it's good to keep leaning, eh? My collecting only started about two years ago and I'd like to think I've read fairly widely during that time, but there's no substitute for experience.

I agree with Bernd, troilite. Nice slice.

I don't think it's pyrite. Troilite (FeS) would be more likely. Interesting chondrule though! Thanks for sharing!
