From the 11th thourgh 18th of June 2011, 7 of our members visited the geologically very interesting island of Sardinia in the Mediterranean. During this one week field excursion we focused on the relationship between the islands geological evolution and the ore deposits there. Our program included "Calamine" supergene non-sulfide Zn mineralization, stratiform mineralization, vein-type and skarn mineralization, hydrothermal dolomitization and visits of industrial mineral quarries such as albitite and kaolinite deposits.

Introduction into the regional geology of the Iglesiente district by Maria Boni (+) Melissa, Cristina and Cyril in the field (+) Some beautiful outcrops of high grade metamorphic rocks on the shore (+) Supergene oxidation of sulfides in the Furtei high-sulfidation epithermal deposit (+) Pierre and Cyril enjoying a well deserved break at the beach. (+) Albitites of hydrothermal origin are mined in this deposit close to the city of Orani for their use in the ceramics industry. (+)

On the rocks: supergene non-sulfide zinc mineralization in carbonate host rocks ("Calamine") (+) SEG Student Chapter Geneva members, our field guide Maria Boni and some local miners after our visit of the Silius fluorite vein deposit (+) Jo, Jose and Honza preparing for their descent to the -500 meters level in the Silius deposit (a fluorite-barite-galena vein type deposit). The mine is currently not in production but under maintenance.
