DudeActually quite keen to see ?reflectance of?the 1050 nm ?peak?with a tungsten halogen light in the near infrared ?for the thinner small tektite.Hopefully can capture the green glow of tektites

Taray, Can you see the Fe+2 UV and 1050nm absorption by doing a reflectance measurement? Dud Sent: Sunday, December 1, 2024 1:31 AM To: [email protected] Subject: Re: [XRF-Page-2] pseudo

This green glow of tektites is due to higher Fe2+ content caused by exposure to reducing agents from high intensity impact . This ferrous visible absorption peak can be analyzed by optical

Dude? Even the big tektite has a a green hue by shining visible light??close to the sides..Otherwise opaque . The??rounded pseudo one is grey to brown to visible transmitted light .No green

Taray, Also in the Saffordite is Zr at 15.79 and possibly a small Y at 14.96 keV. The Tektitebg shows Fe, Rb, Sr, Ba, possibly Y and Ti, Dud Sent: Saturday, November 30, 2024 1:54 AM To:

Here is? a pic of the?? visible light absorbance spectrum? for those without the sgd software

Hi guys? Here is rock bought online. Believe to be a saffordite??,a variety of pseudo tektite. This saffordite being glassy in origin share similar??xrf and specific gravities SG of

Taray, The XRF shows the S at 2.3nm, Cl at 2.62nm, Al at 1.45 nm, and K at 3.36. Dud Sent: Wednesday, October 23, 2024 10:05 AM To: [email protected] Subject: Re: [OpticalSpectroscopyGroup]

There is S in there too When??mixed powdered rock with dil HCl ,some minor effervescence took place? After attempting to dry,there was rotten egg smell suggestive of H2S I tried??casually

Zircon’s are noted for hosting REE and the XRF shows that. The sodalite Cl is also seen in the XRF. The optical spectra is a good match based on that paper. Dud Sent: Wednesday, October 23, 2024

Zircon coexisting with florescent orange sodalite will give yellow florescense This zircon florescense is typically a broad yellow band at 575 nm There??is a slope in this region with both 405 nm

File and pics to note

Pr+3 would have a 624 and a 645nm peak both of which are seen here. Dud Sent: Tuesday, October 22, 2024 7:38 AM To: [email protected] Subject: Re: [OpticalSpectroscopyGroup] [XRF-Page-2] syenite

Dude Is there As in there? Repeated with syenite front face florescence with 365 nm UV Despite 2 rd and 3th order peaks, the peaks are better and coincide with data from articles Similar florescent

Taray, Looking at your optical spectra it looks like at least three of the rounded peaks look to be Sm. Dud Samarium full scam.png Syenite 365nm.png Sent: Monday, October 21, 2024 10:08 AM To:

The new run is seeing Ce, La, Nd, Nb (16.62), Y (14.96) Ga is still pretty weak at 9.27 and maybe Se at 11.27 The REE’s seen in XRF would tend to confirm the optical spectra is showing what is

The files..

Here are??the sites and files which are self explanatory? Chatgpt is a good guide? Fluorescent spectroscopy can enhance XRF analysis by providing complementary information about the sample's

Charles, Same principles of electronic transitions to a higher energy state due to energy absorption. XRF works at the atomic level while UV fluorescence works at the molecular level or in a crystal
