Silica and iron oxide in Saturn rings speak against the presence of
liquid water on Enceladus. If liquid water were present on Enceladus,
primordial silicon and primordial iron would combine with water to
form iron silicate (basalt). On the contrary, the oxygen in E-ring
converts primordial silicon and primordial iron into silica (SiO2)
and iron oxide (Fe2O3) respectively. Non conductivity of silica
and iron oxide and super reactivity of primordial silicon (SiH4 ?)
may have interfered with the performance of particle counter-
analyzer.
