We measured these properties on 22 consolidated tuff samples containing clays and zeolites typically found in hydrothermal systems or in other areas of high water‐rock interactions associated with active volcanic areas. These rocks exhibit unusually high surface conductivity and electrical cementation exponent (2.5–3.3). These features are explained by the highly complex texture of these rocks due to hydration/dissolution processes of the volcanic glass and the formation of clay minerals and zeolites as alteration products. At a pore fluid conductivity of 1.0 ± 0.2 S m<jats:sup>−1</jats:sup>, the streaming potential coupling coefficient ranges from −3.55 to −10.7 mV MPa<jats:sup>−1</jats:sup>. The zeta potential (a key electrochemical property of the pore water/mineral interface) determined from these measurements at <jats:italic>T</jats:italic><jats:sub>0</jats:sub> = 20°C and pH ∼6–7 and corrected for surface conductivity is ∼−28 ± 8 mV at 0.1 <jats:italic>M</jats:italic> NaCl. Two clay‐free samples exhibit a zeta potential ∼−16 ± 5 mV, a value associated with zeolites (clinoptilolite). The temperature dependence of the ζ potential is rather strong with ζ(<jats:italic>T</jats:italic>) = ζ(<jats:italic>T</jats:italic><jats:sub>0</jats:sub>) [1 + ν<jats:sub>ζ</jats:sub> (<jats:italic>T</jats:italic> − <jats:italic>T</jats:italic><jats:sub>0</jats:sub>)], where ν<jats:sub>ζ</jats:sub> ≈ 4.2 × 10<jats:sup>−2</jats:sup> C<jats:sup>−1</jats:sup> in the temperature range 20–60°C.
