Vaesite (?) and other minerals on hydrotermalites, Livorno Province, Tuscany.

Last Updated: 30th Jan 2014

By Giuliano Bettini

As amateur collector, I've noted many similarities among the hydrotermalites of Leghorn hills and the same ones in Northern Apennines.
In particular, I noticed that there are sites with similar minerals.
I put my attention, in particular, on the hydrotermalites of the Rio Popogna, loc. Le Ferriere, Livorno, Livorno Province, Tuscany, Italy.
You may notice the resemblance of the minerals in this place, with other places in the North Apennines, see, eg, Ca' dei Ladri (Silla), Gaggio Montano, Bologna Province, Emilia-Romagna, Italy.
Example:
mineral list at Ca’ dei Ladri.
Anatase, Brookite, Calcite, Dolomite, Jamborite, Millerite, Pyrite, Quartz, Reevesite.
Other significant similiarities are IMO:
- dark bipyramidal quartz crystals up to 5 mm;
- red anatase;
- brookite crystals with the peculiar habitus common in Northern Apennines hydrotermalites (thanks to Marco Pellecchia who drew my attention to this point);
- vaesite crystals grown on the interlacement of needles of millerite;
- crystals of millerite altered in green jamborite;
- orange sphalerite;
- green jamborite and red – orange reevesite.

I post here some images from my Gallery.
