Earlier this year Arizona State University released about a hundred surplus thin sections. This was through a trade with meteorite dealer Anne Black. I bought a few of these slides from her. I chose the only Romero H4 she had because it had an inclusion.
The write up in the Meteoritical Bulletin Database gives only basic information on Romero so I searched further. I found a 1983 paper by Andrew L. Graham of the British Museum that actually addresses an inclusion in Romero. His Acknowledgement at the end of the paper was an even bigger surprise: “I thank Dr. C. B. Moore, Center for Meteorite Studies, Arizona State University, Tempe for the loan of the thin section of Romero (454.4X) containing the inclusion.” ASU! I checked my thin section and there, etched on the back, is ROMERO 454.4x. Mine might not be the same section since the paper cites microprobe data and my section is covered making such work impossible. Also, ASU’s Master list mentions two thin sections in its inventory. Still, the descriptions of Romero and the inclusion are a great fit.
Here I excerpt Dr. Graham’s paper to caption my photos:
