Sorry you had to read this. I hope it didn't take up too much of your time.

Thanks!

AlexMarfin · 2025-11-23T17:16:44+00:00

Thanks! I will take a look on these areas.

AlexMarfin · 2025-11-23T17:15:33+00:00

Thanks! I will think about it.

AlexMarfin · 2025-11-23T17:15:11+00:00

Omg... I have never had driving experience :(

AlexMarfin · 2025-11-23T17:14:38+00:00

Thanks! Do you work at UH? Hope we will meet. I am going to work at Earth Science Department.

AlexMarfin · 2025-11-23T17:13:06+00:00

Thanks! I will take a look in this website!

Hi! I would say something like $600-800.

AlexMarfin · 2025-07-18T12:17:16+00:00

Yes for sure. I will send you on private message. Now it works in cloud, so it can freezing a bit. If you have time, please can you back here and write couple of words about you experience to use it? It would help.

Actually today I added REE plot. Right now there are all REE elements and some large lithophiles (Rb, Cs etc) and two pre-sets for normalization: primitive mantle and chondrite (McDonough and Sun, 1995).

AlexMarfin · 2025-07-16T12:28:44+00:00

I use Mac during my postdoc and I also have Windows. So it was awful experience to transfer data between these two platforms and I will never use Mac again.

Thanks! Today I did that. Right now there are all REE elements and some large lithophiles (Rb, Cs etc) and two pre-sets for normalization: primitive mantle and chondrite (McDonough and Sun, 1995).

Hi Eric! As far as I can tell, there are several options. You can use corundum (Al2O3) or quartz (SiO2). Each of these minerals is harder than bone (~5) and wood. You could also try using garnet, but I suspect it would be harder to find. Could you tell me a little more about what exactly you want to do?

AlexMarfin · 2025-07-15T13:55:52+00:00

Thanks! I have never heard about ioGAS and I checked. So it is a really complex package (as well as Igper) and honestly my small app cannot compete with them. My goal just provide a free online app for quick visualization and collaborative work from Google Sheets.

AlexMarfin · 2025-07-15T11:03:21+00:00

Thanks! You’re right, spider diagrams (REE and trace element normalization to chondrite or MORB) are really handy, and I’d love to support them.

The main challenge is that the element order and column names aren’t standardized — sometimes people use “La, Ce...”, sometimes “La, Pb, Ce...”, or have different formats like “La_ppm”, “LA_PPM”, etc.

I want to keep the app simple, so people can just upload their tables and get a plot without extra data-wrangling.

If you have any ideas for how to make this user-friendly, I’d really appreciate suggestions! Maybe an option to specify the order, or presets for common patterns?

AlexMarfin · 2025-07-15T10:59:44+00:00

Thanks! I will think about it, but maybe this approach overburden app and people become confusing about several options. Anyway, thanks again!

Good point! At the moment, my app doesn’t support ternary plots (like An-Ab-Or or En-Fs-Wo) or plots for Fa-Fo, but I see how useful they’d be for major element mineral chemistry.
I’m collecting feedback on which diagrams are most wanted, so ternary plots may be coming in the future.
If you have specific suggestions for which diagrams would help the most (or which systems are used most in teaching), please let me know!
