PhotosRhodochrosite - Lavrion District Mines, Lavreotiki, East Attica, Attica, Greece

Although there is a lengthy explanation why this piece is supposed to be from the Lavrion Mining District I personally believe that this specimen is definitively NOT from there.

Cheers,

It reminds me of some that I've seen from Cavnic, Romania.

Or Cassandra mines, Chalkidiki.

Totally agree with Branko. Deleted.

For the record - the wishful-thinking (I am polite here) comment in the caption read:

"(...)

Obtained from Chris Spiromitros who feels strongly that the Lavrion locality is correct - Wolfgang Wendel and others who have been consulted are said to be in agreement. The crystal habit and color and associates are quite consistent with Cavnic, Romania. However, the overall habit of the aragonite is very suggestive of a Greek origin and Chris feels confident is not from Cassandra mines. After pursuing the research for over a year Chris believes that Anmeones area, Lavrion is the likely locality. I have subsequently heard from Fernando Metelli, the Italian collector who has an identical specimen attributed to Lavrion. He is the source of Chris' specimen. He obtained it from an Italian collector in Turin from a beneficiary who was liquidating it. It belonged to his mother and father, a mineral collecting team. He spent much time in Lavrion, she is Italian. His specimen has the same label and he is comfortable with the locality."

why was the photo deleted rather than just relegated to the user's personal gallery? There must be hundreds (edit: thousands?) of photos here that are either incorrectly IDed, attributed to an incorrect locality, or are otherwise simply terrible. But are such photos typically deleted?

There are no strict rules. I prefer to delete grossly erroneous photos.

In any case, all deleted photos are still in the database and can be retrieved.

Well, OK, but the ID was presumably correct and even the locality, while disputed here, seemed to have been supported by at least a couple of people according to its caption. So I'm not sure I'd call that "grossly erroneous". It's not as if the uploader labeled it "diamond - the Moon".

I only bring this up because while in this case that one photo was just one from among multi-thousands of photos uploaded by this user, and so one deleted questioned photo might not be missed, it could have just as easily been something uploaded for personal posterity from a small-time collector who might wonder (quite fairly, I might add) why simply because of a questioned locality, their photo was not only demoted from the public gallery (yes to that... no questioned IDs or localities should be in the public galleries) but in fact deleted altogether. Maybe we do need more defined rules for this?

> So I'm not sure I'd call that "grossly erroneous".

Well, we (Branko and me) consider ourselves Lavrion specialists (Branko has worked on the mineralogy of the Lavrion mines for decades, based on hundreds of underground collecting trips; and he wrote a PhD thesis on the deposit) and we can guarantee you that these people are simply wrong. No local Greek collectors have any such specimens in their collections.

I agree that the ID was probably correct.

The uploader allowed us managers to do anything (correction, deletion) with the uploaded photos, i.e. no notification or message necessary.

In my general opinion we should in general be more strict and many more photos should be deleted (after discussions and especially if the user cannot provide any convincing evidence for either ID or locality attribution).
