PhotosMistaken identity... specimen from Cuasso al Monte, Italy

18th Apr 2024 20:44 UTCBeppe Finello Expert

Dolomite, Bertrandite, Fluorite, Synchysite-(Y)

Laghetto Quarry, Cavagnano, Cuasso al Monte, Varese Province, Lombardy, Italy

A few days ago I suspended the publication of this photo because the yellow rosettes are definitely not synchysite-(Ce); I therefore inserted the comment in this sense in the appropriate form reserved and visible only to experts and managers; it is certainly a carbonate (probably sideritre) in aggregates of selliform crystals that have nothing to do with synchysite. I therefore ask Mr. Geoff Van Horn, who has the qualification of an expert and was certainly able to see my comment, to take note of it and modify the attribution and description. Thank you.

I see that there is a question about the identity of a mineral, but I don't see a note about which one. Unless a DM was sent, I think that the message didn't reach Geoff.

The day before yesterday I had inserted the message in "Notes:(visible only to managers and photo approval experts)" and I had placed the check mark on "Unapproved"; Yesterday I saw that the note was deleted and the photo was approved again as "Public galleries" without any modification. I specify that I don't know this Mr. Geoff Van Horn and therefore there is nothing personal about him; I took the liberty of reporting the error simply because I have unfortunately noticed that in recent years, several photos have been approved with incorrect or in some cases even false information. I believe it should be in the interest of all enthusiasts to ensure the correctness of the information published.

Agree - clearly a carbonate (curved rhombohedra). Message sent.

20th Apr 2024 02:04 UTCGeoff Van Horn Expert

Yeah. Still waiting for a message about this. I only checked the comments because the view count is too high.

The Synchisites are the small reddish brown crystals, that I have marked with green arrows. Most of the rare minerals at Cuasso al Monte are smaller than you think.

Uwe, thank you for shedding light on the identity of some of the minerals in this photo.

I assume the fluorite is quite obvious too: the glassy crystal in the left lower corner.

On the other hand, the bertrandite is not obvious. Maybe the small glassy reflection just above the (bottom) white crystal in the lower middle/right?

And are there two generations of dolomite visible here? Or are these two different minerals?

Finally, the big blocky flesh-colored crystals, do they belong to the feldspar group?

My only question is, what is the mineral circled in blue. Red arrow points to bertrandite, yellow arrow is fluorite, green arrow is dolomite, Uwe identified the synchysite, but I’m still not sure what the circled mineral is. I thought this was a specimen of two flavors of synchysite + other minerals.

Further, I don’t know if it’s a bug or a process failure, but I never received a notification on this. I saw the photo was pending, then approved, then pending again. The only reason I found this thread was because I dug deeper into why the views had gone so high on a pending image and found the crass message from Beppe accusing me of ignoring him and demanding I take action.

but I never received a notification on this.

If it's not in your spam folder, your provider could have a too strict firewall.

Did you get any previous messages concerning your photos?

23rd Apr 2024 16:39 UTCRalph S Bottrill 🌟 Manager

I would guess that the yellowish mineral in the circled area is a ferroan dolomite, and the squarish white crystals below are probably bertrandite?

23rd Apr 2024 17:38 UTCDavid Von Bargen Manager

but I never received a notification on this.

If you go to your gallery, you can look at images that have unresolved issues (show drop down selection)

Then go to those images.

Then select photo questioned.

This is the notification that was sent.

I received a message from Debbie 13 weeks ago with no issue. I’ve checked the settings on my account here and searched my spam and junk folders but found nothing. I must admit I don’t generally return to images I’ve uploaded to check for comments. I also have a few outstanding unresolved issues for minerals I have to dig out of cold storage to resolve. I’ll work on those issues before uploading new images. So it’s more apparent when there are issues.

24th Apr 2024 12:59 UTCUwe Kolitsch Manager

Thanks Geoff. I have just sent a test message concerning one of your recent photos. Please check if an e-mail has arrived.

23rd Apr 2024 18:35 UTCBeppe Finello Expert

Dear Geoff, first of all, I apologize for the "crass" message in which I unfairly accused you of ignoring my observations on the matter, it was absolutely not my intention to offend you. I was convinced that all users with the qualification of expert or manager were able to read the comments inserted in the "Notes" box; Therefore, having noted that you have the qualification of expert, I thought it simpler and more immediate to write my observations there. The following day, seeing that the photo had been re-approved without making any changes, I wrongly assumed that you had simply reselected the public galleries button ignoring the observation and I therefore reported the matter publicly, not realizing that the approval had instead been made by somebody else.

About the classification of the various species present in your sample, obviously in addition to orthoclase and quartz we can see:

pale purple transparent cubic crystal of fluorite (orange arrow),

Beige rhombohedral crystals of dolomite (green arrow),

small brick-red pseudohexagonal prismatic crystals of synchysite-(Y),

very small and thin colorless prismatic crystals with pointed termination of bertrandite (red arrow),

saddle-shaped crystals (outlined in blue) without analysis only more or less reliable hypotheses can be formulated

it could be ankerite or dolomite or siderite or even Iron-bearing Magnesite or as often happens with these carbonates, a mixture of two or more species.

No worries. Identity has been updated and my backlog of image issues should now be cleared up.
