Adam and list,
Your photos show a very interesting meteorite. The second image reminds me
of the Babadus impact melt from Rochechouart Crater, France.
Thanks for the photos. Fred Olsen, Denver

> Elongated multi-colored glass objects that look like Pele's hairs imbedded

> Perfectly spherical vesicles present in matrix
> 2mm weathering rind under a very thin glass crust on the side with
lip-over.
> Contain several highly refractive minerals never before observed in any

> Is more friable than a Nahklite meaning it did not lay in the desert very

> Is definitely not related to the HED group judging from ratios measured in

> We do not want to speculate about its origin until more testing is done.
