GeneralQuest about Herderite
28th Jul 2012 12:33 UTCPaolo Franchi
a week ago i upload two photos of my Herderite, but there aren't on your database or in Herderite photo list, where there are only old images.
Why? i have to change the procedure? Don't like photo light or quality? what i have wrong?

For me, they look like Herderite/Hydroxylherderite. You can not differ this two minerals by visual way! I have some xtals from the Steininger quarry near Luftenberg, Upper Austria. The exactly ID Herderite/Hydroxylherderite was made by infrared spectroscopy in Moscow!

i buy this specimen from Athos Locatelli at Edolo mineral show this mounth.
On the label there is written:
Herderite on Muscovite
Shigar valley, Skardu, Baltistan, Northern areas, Pakistan
The crystal is 2,6 x 2,0 x 0,9 cm

You have changed the name of the specimens, on your photos, from "herderite" to "herderite-hydroxylherderite series", according to my suggestion, and I have already approved both.
Herderite is quite rare; to my knowledge there are only 2 confirmed localities of true herderite (that should contain more than 5,86% F, that is the mid-term between herderite and hydroxylherderite): Mogok, Mianmar, and Funil mine, Medina, Minas Gerais, Brazil; all other specimens on Mindat herderite photo gallery, from other localities, are questionable.

Luftenberg, Upper Austria, Austria is a further locality for Herderite (F>OH). This mineral was analysed by IR-spectroscopy (Brandstetter G. & Reich M. (1998); Brandstetter G. & Reich M. (1999)). So I don´t know, why Herderite is questionable for this locality here on Mindat.

i uploaded the photo as herderite, not as hydroxylherderite. and it is indeed analyzed! is it possible for a mindat manager to add "herderite" to luftenberg locality? would be nice!
but keep in mind: most analyzed crystals from this locality are hydroxyl-herderites.......
by the way - i still think your crystal is europes best, but it needs a better photo!

I put a picture of Hidroxilherderita analyzed.
A greeting.
