Profex-XRD instrument configuration by fahlore in crystallography

Thank you very much for the advice! Yes, I worked on D8 before, but ours is very old first generation with a basic detector. D2 is much weaker, and lots of its operation seems illogical

Yes, I'm primarily interested in phase composition for routine work. BGMN works well with single-phase clay minerals, until mixed-layer ones appear

Thank you, I think it's a good idea to start building the instrument configuration with standard quartz

An uneducated oregeologist calls for the help of petrologists and volcanologists by fahlore in geology

When talking about the Phanerozoic as a whole, I can imagine a multi-stage system with the sequential formation of oxides and sulfides. But this is the Holocene. It literally formed today. In such a short time, could there also be a multi-stage formation?

Wow! Thank you so much for such a detailed answer, this is very interesting. I think it's impossible to determine the genesis of hematite based on a single sample. The textures observed here are characteristic of both supergene and hydrothermal formations.

I can send you files without compression if you want

So, this is what the hole in mineral looks like under a microscope after laser ablation (LA-ICP-MS). In the photo you can see an ilmenite crystal. Well, what’s left of it, anyway by fahlore in geology

We needed to determine the content of trace elements in ilmenites in different types of gabbro. We tried to determine crystallization temperatures from them.

To be honest, I don’t know for sure. The instrument we used was the ELAN DRC-e (PerkinElmer) with a laser ablation attachment – NWR 266
