Although I like such specimen (otherwise I wouldn't have acquired it) I'm not proud of the photos you mention. They lack some contrast with the background that I wasn't able to solve, showing also some indefinition of the calcite crystals' edges. However, I thank you for your comment, am glad you like the piece, and must add here that I still have to learn a lot from you concerning minerals photography.

Thanks Carles i do appreciate your kind words, I think ive still a long way to go with mineral photography, I will probably always feel like that, sometimes I think its having a scientific background, Im always trying to improve my methods and im never satisfied.

We all have a long way to go! You will never be satisfied with your photos. Sure, I know what I say...
Good luck!

Vivianite, siderite
Group of translucent to transparent sharp vivianite crystals with a rich green color, showing the typical tabular habit with a hexagonal shape, set on a matrix of dark brown crystallized siderite with some pyrite at its bottom. From a new find at Colavi mine, which until now had not been known for producing quality vivianite specimens. This very find has yielded too a number of excellent ludlamite groups on the same dark brown siderite and pyrite matrix. Vivianite crystals undamaged. Overall size: 78 mm x 65 mm. Main vivianite crystal: 30 mm x 16 mm x 8 mm. Weight: 216 g.
Colavi Mine, Machacamarca, Cornelio Saavedra, Potosí, Bolivia.

Hi Carles,
Has the real locality for these finally been determined? (BTW, nice specimen too!)
Bob |
Not sure yet, Berthold Ottens is working on it. |
Good news, Berthold Ottens finally find out the right locality for these Chalcopyrites with Siderite, for the moment we can say:
Hezhang County, Bijie Prefecture, Guizhou, China
and in three months we will know the name of the mine. According Berthold the paragenesis is very simple: just Chalcopyrite, Siderite, Tetrahedrite and Calcite.
Good job Berthold! ;-)

Jordi,
IMHO that cannot be considered a locality yet. Hezhang County is neither a city nor a town, but an administrative area that might have a large extension.
In addition, and according to Wikipedia, Hezhang County and Bijie Prefecture belong to the Guizhou province, not Guangxi.
Let's wait for Berthold to make that data more accurate before amending our records.
Thanks for the info!

Thanks Carles, I already modified "Guangxi" for "Guizhou" and "locality" for "details" in the title of the other thread The right details for the new Chinese Chalcopyrites with Siderite!
As I said: "Berthold Ottens finally find out the right locality for these Chalcopyrites with Siderite, for the moment we can say... and in three months we will know the name of the mine ..."
you can amend your records now or then, this is up you.
