Dypingite

Vorrei sapere se la Dypingite è confermata a Brosso. Grazie
Ferdinando

Nessuna conferma. L'occorrenza rimane dubitativa.

Grazie dell'informazione. A scanso di equivoci e per chiarirsi, le sferulette bianche associate alla Canavesite non hanno ancora un nome? Questo perchè su Mindat le trovo tutte come Dypingite.

Esatto Ferdinando, le sferette bianche associate alla canavesite sono state dubitativamente attribuite a dypingite (ma anche a "hydrodypingite" e "yoshikawaite". Quindi, in parole povere, non si sa bene cosa siano e recenti studi, peraltro non terminati e ancora da confermare, paiono aver individuato in associazione con la canavesite due diverse fasi minerali.

Tutte le informazioni - al momento - sono dubbie e comunque incomplete. Nulla di certo.

Scusa Marco non trovo riferimenti per la yoshikawaite.
Cos'è un sinonimo o una varietà di dypingite?

"Yoshikawaite" è un nome non approvato dall'IMA e sta a individuare (probabilmente) la dypingite (o qualcosa di simile) oppure un possibile dimorfo dell'artinite.

Hi Italian friends,

I understand from this topic that the dypingite from Brosso miner is questionable. I have some samples of this combination; globular "dypingite" aggregates and fibrous canavesite on an ore matrix, mainly pyrrhotite. Those are from a sample I bought many years ago. I don't realy understand Italian very well, but would like very much to get informed what your conclusions regarding this material is.

Regards
Peter

Ciao Peter,
from this topic looks like the dypingite from Brosso is still questionable because the analysis didn't confirm the specie yet.
According to the infos provided by Marco Ciriotti, the spheres could be "dypingite", "yoshikawaite" and/or a dymorph of artinite.
I'm a little bit astonished by this new, as well. I thought that the analysis were confirmed.
Can't way the analysis!!

Marco, what about nesquehonite (often given as "inderite" and not easily distinguishable at naked eye, as far as I remember...by I might be wrong...) from Brosso?is this confirmed or is questionable and unconfirmed as well?

Yes Peter,
the "dypingite" of your samples and, of course, all "dypingite" specimens from Brosso, are questionable.
The phase was never (see the type-description of canavesite) well characterized and a very recent work, not yet complete, seems to demonstrate that, probably not in all specimens (that was found in two different localities in the same tunnel), two different phases occurr. [In mindat "dypingite" was ever indicated as questionable].

Study are not complete, at today, and I am not sure if it will be possible to finish the work.
Ciao. Marco

Nesquehonite and inderite was found at Brosso mine, but in other tunnel.

The best reference on Brosso mine minerals is:
Campostrini, I. (2001): Le miniere di Brosso. Monografie XXIX. Museo Regionale di Scienze Naturali, Ed., Torino, 185 pp.
that confirm all the things here posted except the fact of the new study on "dypingite-like phases".
