Some considerations on flow, heat and chemical composition of Italian hot springs
Main Article Content
Abstract
Tlie flow, the temperature and the chemical composition
of Italian hot springs are eonsidered from the geopliysical and geochemical
points of view. At Guardia Piemontese, the spring temperature deereases in
the rainy season while the flow increases, the phase lag of this variation from
tlie rain being about two months. This may suggest that the precipitation
aliments the source of the hot spring itself or it causes an increase of groundwater
mixing to tlie hot spring.
In Italy, the hot water output of each hot spring is generally less
than the quantity of corresponding recharged water from the precipitation
in the basili, and tliis relation is also kept in the geothermal steam fleld
of Larderello. The annual tliermal outputs of Italian hot springs are
of order of IO14 cai at maximum. We can extraet geochemically some
groups of water from the Italian minerai waters: thev are a high saline water
being regarded as fossil or oil-field water, a water being similar to the sea
water, a water of which main soluble component is CaS04, and a middle
type between last two waters.
