nechesh,

Thank you for keeping me honest. I have been out of that "community" for a long time... and I do not mean present my self as an "expert" to compete with any one, especially with Dr. Piaskowski. I mean "we" as the scientific community.

The Electron Micro Probe has been the main tool used in diagnosing meteorites for sometime now... just ask your friends who collect meteorites and send them in to Universities around the world for analysis. I use Arizona State University (ASU) in Tempe, AZ (Center for Meteorite Studies) because that’s where I went to school. Dr. Lewis also holds and analyzed many of the lunar samples gathered by NASA there at the Lab. I am sure Dr. Piaskowski is aware of this and the "EMP" techniques and data analysis. The question would be the sample (or how dilute the meteoritic material would be in a forged blade, then picking out parts per million of trace elements can be a challenge).

But the trace elements are a definite fingerprint for cosmic origin!

Jim,

You are right. There is no question about it. If there is enough meteoritic material, it can be detected. But like you... I would have second thoughts about testing for it too (even though it is not destructive, it creates a blemish).
