Abstrakt

This work studies the possibility of serpentinization at the water/rock boundary of Enceladus (pH 7-9, 25-50 bars, and 0-50°C), and further estimates the hydrogen production rates. Thermodynamic databases were created with the DBCreate program [10], and geochemical modeling was applied with the EQ3/6 software package [2]. The chemical composition of the subsurface aquifer is assumed to be similar to the plumes. Nine scenarios were tested to specify the core composition. It is shown that serpentinization seems to be possible at the water/rock boundary on Enceladus if an iron-rich end-member is present in the core.
