(Miniera Santa Lucia, Fluminimaggiore, Carbonia-Iglesias, Sardegna, Italia)
This important mine is only 4 km west from Fluminimaggiore Village. The real development of this mine is most recent as it starts in 1943 and the mining activity ended in 1980. This mine complex is famous to most collectors for its interesting and beautiful samples of barite, fluorite and linarite, has given also other great mineralogical surprises during the last 20 years, as you can see from the list.
The mineralization (mainly represented by barite, fluorite, galena, quartz, sphalerite, chalcopyrite) is connected to an intrusion of granitic masses which intersected sedimentary rocks of probable Cambrian and Ordovician age. Probably happened a remobilization of primary and more ancient deposits which were concentrated by hydrothermal processes along the contact between Ordovician and Cambrian units.
