Are you using a shield of any sort?
Yes
My lead scatter is very minimal?
I place a graded shield of Fe and Al where risk of scatter is max
Since my beam is narrow,my sample/sensor is a good distance away minimizing systemic peaks
I also place a small??secondary collimator window at the probe end?
This helps to minimize Ni to a large extent?

Typo for pancake probe meant for radioactivity.
?I checked SG with my??pocket digital scale ,thread and beaker of water?
Putting a thread was not a problem since there is already a small hole meant for pendants?
Done it before in this forum
SG??is 2.40 lke yours
Regarding magnetic it is very subtle??if present.
My meteorite specimen sticks loosely to a strong Nd magnet
This tektite doesn’t at all
Try using a sensitive pocket digital scale and Nd magnet instead?
My digital scale attracts magnets?
?By a slight modification placing tektite on a light tall plastic sitting on the scale solves the problem?
It is very faintly magnetic??from my analysis?

Taray,

They have not yet identified an impact site yet for these Tektites.? I do not have much knowledge of Geology or Geochemistry, but within the abstacts I provided, (see original post), the term "mafic" keeps coming up.? I believe this means basalt instead of granite.

If you have a scale that can weigh the Tektite to within 2 or 3 digits accuracy, use this easy procedure below to calculate specific gravity.? Mine was 2.4.

Charles tested my Tektite with a magnet.? He says he doesn't think there was any attraction.

Your spectrum is very interesting in that it has fewer lines and it does not have that huge hump near barium Ka1 compared to mine (as performed by Charles Young).? The hump looks like Compton Scatter to me.? Are you using a shield of any sort?? I think some of my Tektites lines (Pb, Cu?) are from Charles shield, but I believe the Ni is real.
