Readjusted setup? with better results My tektites with a different shape and size share similar xrf characteristics Both are from the same strewnfield. Te does not? seem to fit in despite going? on

Will try improving my count rate My detector /sample distance moved apart slightly??by 1 cm It is significant for a narrow beam/secondary collimation system? Bring it closer again later this

Me too.? I have always had an interest in Meteorites (and such), but I really got the bug after reading "The Fallen Sky" by Christopher Cokinos.? It tells the story of how meteorites became a

Search for physics with forum search engine in xrf page2 Go to xrf X-ray physics? The file is xrf distance??pdf

Taray, Can you give us a link to that beam collimation article it sounds like good information. Also note that tektites aren’t part of the meteorite but the melted terrestrial rock and soil ejecta

This helps to minimize Ni to a large extent I may have been exaggerating a bit( can’t help it sometimes!) But it appears to decrease Ni and other scattering event??by the secondary

Great!? I would appreciate it!? Charles said he would reach out to you regarding the Tektite. Mike L.

Mike, I’d like to run that Tekite before you get it back from Charles if that’s ok with you and Charles. Dud Sent: Saturday, August 3, 2024 10:32 AM To: [email protected] Subject: Re:

I knew what you meant regarding the pancake probe.?? Charles and I both used a scaler and long timed counts to check for radioactivity.? There is a small (9 cpm), but statistically significant

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

Mike 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

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

What type of chinese terrestrial rock was?hit by the meteor? From the video ,answer is granite

Here are the files

Mike 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

Yes, 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

Mike Ordered the pendant version 2 days ago Should be getting it soon BTW I have previously seen “tellurium” in??some??of my xray spectrums??which I could not??explain? ?This is

From a google search Glass typically contains about 0.3% arsenic oxides or arsenates, but some types of glass can contain up to 1.5% arsenic trioxide. Glass manufacturers add arsenic to reduce bubbles
