My visit to Italy was mostly a vacation just to relax so I did not do much research to find museums or fossil/mineral sites to visit. I read that it is illegal to collect fossils in Italy and their museums have some odd schedules about being open. That said, I did keep my eyes open to geological features at places we stopped to visit. One town we spent a few hours at was San Gimignano, Italy.
One of the walls had a stone block that had some fossils in it. The fossil I could see was a small gastropod calcite fossil about 2 cm in diameter. The rest of the brown block had broken shell fragment fossils.
A nearby stone in the same wall had an interesting pattern on it. Could it be volcanic in origin?
Near the wall were olive trees, here is picture of some baby olives.
Here is a panoramic view from San Gimignano of the surrounding countryside:
Here is a dark quartz crystal in matrix from the quarries at Monterigginoi near Siena. Learn more about the locality here: http://www.mindat.org/loc-125546.html
This green mineral might be malachite. The specimen was found at Serrabottini Massa Marittima in Grosseto Province of Tuscany Italy. Learn more about this locality here: http://www.mindat.org/loc-64651.html
The last mineral picture is a piece of galena from unknown locality.
