Here is my China tektite?
Light weight and looks quite flat
Very weakly magnetic if tested with a neodymium magnet and digital weighing scale
Not magnetic to pancake probe
Xrf wise it is similar to your sample minus systemic peaks
No Te or Ag
Fe with no Ni?
What type of chinese terrestrial rock of hit by the meteor?
Pic and mca to follow next
Partly broken when attempting to remove from pendant attachment?

I got excited when Dud spotted Te in both my Am241 meteorite spectrum and Charles X-ray spectrum of the Tektite.? But then I looked at several Am241 scans, and it is often there.? Ref msg 214.? I superimposed spectrums of water, aluminum, and copper.? I was studying Compton and Raleigh scattering. All three scans appeared to show something around? 27 keV (i.e. "Te") with an equal peak. It has to be some kind of systemic error with Am241.?

Similarly, the Ag line is pretty weak in the Am241 meteorite scan and buried in anode noise with the Tektite scan.? Probably not much I can do there.

I'm going to think about it for a while.? I look forward to what you can do with the pendant.
