WG9-TK3Pisoid-limestone

08450940015816585658836.jpg
Saturnia, Manciano, Grosseto Province, Tuscany, Italy

Largest Crystal Size: 3 mm

Pisoids are rounded spheroids carbonate grains, composed of concentric laminae which surround organic or inorganic nucleus.
The mineral waters from which they originate are of the sulphurous carbon type, earthy alkaline bicarbonate sulphate. They gush out at a constant temperature of 37.5° from a residual volcanic activity of the nearby Mount Amiata (extinct Pleistocenic volcano) and through an underground path lasting 40 years they mineralize by absorbing carbon dioxide. The minerals dissolved in the waters and coming from the rocks crossed by the effect of CO2 redeposited releasing sulfur, calcium, magnesium and sulphates, thus forming the well-known travertines and these particular limestone formations.
The individual grains are greater than 2 millimeters, but can also exceed 2 centimeters across.

Santo Stefano quarry

04228270015793647162729.jpg
S. Stefano quarry, Borzoli, Genoa, Genoa, Liguria, Italy

The rocky material (mainly metabasalt) was extracted from the Santo Stefano quarry for aggregates. At the beginning of the 90s a railway tunnel "Fosso dei lupi" of about 2000 meters was dug under the quarry to connect the new port of Genova Prà with the railway line for the lower Piedmont. Together with this tunnel, two others were dug in the mountains behind: a "Gazzo" carved in limestone and in the Triassic Dolomites and another "Doria" that crossed ultra-basic rocks. In ethe chronicles of those times I remember reading about a huge cave that came to light during the excavation of the "Gazzo" gallery but of which there is little news.
About 2011 two other tunnels and road curves were excavated, this time passing through the quarry and visible in the photo, used for the service to the road that climbs the mountain behind it and that leads to the municipal landfill of "Scarpino"
This is a brief chronicle of the facts that remind me of my mind and which I believe should be mentioned.
