UV florescent spectroscopy goes hand in hand with xrf

Dude?

Will attempt a?longer acquisition time for xrf?

Some rocks deserve more attention?

Not sure dissolving this alkaline rock in dil HCl and?shooting through a quartz cuvette will help in 365UV florescent spectrum.

Quite an interesting specimen for analysis?

Taray,

I looked for Ga but it’s too weak to say. Perhaps with a longer count time and running the HV down to 20 kV may help bring out the lower energy elements

The optical data are overwhelmed by the 365nm producing the second order peak at 730 and even the 3^rd order at 1095nm.

The broad fluorescence peak shows four convolved peaks that are probably rare earths.

Well syenite is found in China based on this article?

This Fangcheng type florescent rocks are sold of as yooperlites or healing stones.

Well the composition of mine is similar to this??chinese article samples.

They indeed contain lots of Zr

Besides Zr ,there is also peaks suggestive of Ce and??Ba which is dominant .

There could??be a Ga peak there as well besides other peaks.

I generally like to keep my acquisition times short to avoid any untoward circumstances with my X-ray machine.

Did a 365 nm florescent spectrum using C8 Convo

It shows the florescence culmating in orange

Not laser strong for peak identification?

Spectroglyph software expired?

Enclose article and narran UV spectroscopy file

Maybe Dude can convert it for me if necessary?

Another interesting difference with granite is their magnetism

Copied text..

?It contains much more ferromagnesian minerals biotite and hornblende, and rare pyrox- ene. The specific gravity varies with the constituent minerals and their proportion ranging between 2.6 and 2.8.?

Files??sent

Thank you?
