In the Cammissinone mine, in the municipality of Zogno (BG) at the time of mining were discovered magnificent fluorite crystallizations but, unfortunately, almost all have been destroyed in the hoppers.

So little has been preserved.

After the abandonment of industrial activities, mineral collectors, working in the "tails" of the remaining veins, still managed to find some crystalized cavities.

Authors of a beautiful discovery are three mineral seekers from Viarago, a town located in Trentino region, Italy: FEDERICO MORELLI, SANDRO ZAMPEDRI E UGO ZAMPEDRI.

The fluorite specimens are deep purple colour and with large sizes.

An interesting sample has been donated to the Natural History Museum of Milan.

Three beautiful and huge specimens of this Fluorite find from Zogno, will be displayed at BOLOGNA MINERAL SHOW | 08/09/10 March 2013 |

UNIPOL Arena, Gino Cervi avenue, 2 – Casalecchio di Reno (BO)

The special exhibition is dedicated to the Mines and Minerals of the Campiglia area (Tuscany). Three millennia of mining activities (from Etruscan times to the modern era) of an amazing geo-mineralogical territory that, together with the nearby Elba Island, can be defined as a great open-air mineralogical museum.



Since the XIX century, the gorgeous ilvaite crystals from the Temperino and Lanzi mine, together with the specimens from Rio Marina type-locality (Elba Island), have been strongly requested by Museums and private collections. They represented the exclusive aesthetic specimens on the market until the recent occurrences in Russia, Greece and Mongolia. Especially during the 70's, the exploitation activities at the Temperino mine (Ortaccio-Le Marchand area) provided several beautiful specimens with large black prismatic crystals up to 8 cm on quartz druses. A selection of the best ilvaite specimens from Campiglia mining area will be displayed in a special exhibition at the Bologna Mineral Show.


Talking about the Campiglia mining area does not mean only ilvaite; for at least three millennia, Etruscan, Roman, Pisan, Florentine, Tyrolese, French, English and Italian miners have extracted several metals (copper, iron, silver, lead, zinc and tin) and industrial minerals (feldspars, alum and iron sulphates) from the Campiglia mining area. The link between human settlements and mineral resources in Campiglia is an unbroken thread. Here, for millennia, several stages of metal extraction and processing produced a complex stratified record from the Etruscans until 1976, year of the closing. The Archaeological Mines Park of San Silvestro has saved the memory of this long mining and human history providing an extraordinary opportunity for new mining, geological and archaeological routes.


The geological history of this territory is complex and fascinating and the mineralogical wealth of the Campiglia area excite researchers and collectors. The mineral species identified are more than hundreds and one of them, the campigliaite, has been characterized for the first time on specimens from the Temperino mine. Several, common and rare mineral species have been identified in recent years (brochantite, serpierite, hedyphane, antlerite, connellite and so on); but significant are also the aesthetic mineral occurrences: auricalcite from Monte Spinosa and Buche al Ferro mines, large quartz and gypsum crystals from Temperino and Lanzi mines, the huge scapolite crystals from the Maffei quarry and so on. Outstanding are the relationships between magmatic rocks (granite and porphyry) and hydrothermal ones (skarn), who led a group of scientists from the Consiglio Nazionale delle Ricerche and the University of Pisa to carry out a detailed geo-mineralogical study of underground works in the Temperino-Lanzi mining area. This and more at the Bologna Mineral Show in a special exhibition that joins the mining history, the best minerals and the current scientific mineralogy with its recent discoveries.

Given the great success collecting by the demonstration of alluvial gold panning sifting the sands of the rivers, this year at the Bologna Mineral Show will be set up again the diorama that recreates the bed of a river, to allow all visitors to try in search of the precious metal with the discovery of real gold flakes.

The demonstration will be carried out by a popular researcher Biella who has devoted his life to the discovery of gold-bearing alluvial deposits along the rivers and streams of the Italian region of Piedmont. To visitors who will stop at this area, will be explained all the various research techniques, from the traditional "batea" to the most complex "channel".

So do not miss to visit the 44th Bologna Mineral Show on March 8 - 9 - 10, 2013 , from 9:00 to 19:00 at the Unipol Arena - Gino Cervi avenue, 2, Casalecchio di Reno (Bologna).

The National Parks Entity of Asti (region of Piedmont, ITALY) manages the protected natural areas of the province of Asti in which the most important consideration is the significant presence of fossils of marine organisms and to enhance these findings is building the Asti Museum of Paleontology.

In the displaying area located within the event of Bologna Mineral Show, through a series of descriptive panels will be explained the world of paleontological fossils and the actuality of Central Piedmont.

It will be exhibited also reconstruction of the lower jaw of the giant megalodon shark fossil, which dominated the seas of most of the world about 20 million years ago, along with numerous fossil shells dating back to about 3 million years ago, extracted from the Asti areas.

Written by Aleksander Recnik, teacher of nanostructured materials at the Institute "J. Stefan ", Ljubljana (Slovenia), the book:

- It is the most comprehensive study about the mineralogy of the famous deposits of mercury at Idria, Slovenia, the second largest one in the world;

- Retraces the past several hundred years old of Idria mines, with particular reference to the history of the layer mineralogy;

- It updates and expands the mineralogical knowledges, thanks to new and in-depth investigations;

- It is richly illustrated with 160 color photographs and 24 drawings about specimens of exceptional beauty.

In the first chapter, the Author introduces us to the long history of mining in Idrija and its connection with the mineralogy. The latter is explained in terms of geological processes active during the formation of the layer. Among them, the hydrocarbons contained in the wall-rocks have had a role in the crystallization of mineralogical species.

The central part of the book is dedicated to the main mineral of the ore, cinnabar, whose crystals are presented with a wide variety of shapes: the most unique is certainly the one of twins by permeation side.

The book was written with the intent of reaching a wide audience, not only "insiders" (geologists, mineralogists, crystallographers), but also all those interested in the history of mineralogy and collecting in Idrija.

The Italian translation was edited by Marco Pellecchia and Christian Mavris.

The presentation of the book and the meeting with the Author will be in the VIP Lounge at Unipol Arena on day of Sathurday March 9 at 11 am.
