TL;DR: The peridotites are associated with basaltic dikes and are in tectonic contact with a metamorphic unit and with post-Mesozoic sedimentary units as mentioned in this paper.

TL;DR: In this paper, a large number of geochemical data gathered on the Gruppo di Voltri springs confirm that progressive interaction of meteoric waters with ultramafic rocks variably affected by serpentinization leads initially to the formation of Mg-H CO3 waters when the system is open to CO2, and Na-HCO3 and Ca-OH type water upon further interaction with the rock, under highly reducing closed-system conditions with respect to CO 2.

TL;DR: In this article, 30 groundwaters sampled in La Spezia Province, Italy, have Mg-HCO3 to Ca-CO3 composition, undetectable Cr(III) contents, and virtually equal concentrations of total dissolved Cr and Cr(VI).

TL;DR: In a recent survey of the spring waters of the Genova province, many neutral Mg-HCO3 waters and some high-pH, Ca-OH waters were found in association with serpentinites.

TL;DR: In this paper, the acid and base dissociation constants of FeO and Fe2O3 components in silicate melts are defined in terms of observed relationships between atomistic properties of dissolved oxides (nephelauxetic parameters, electronegativity, fractional ionic character of the bond) and polymerization constants in simple systems.
