Abstract

An initial geochemical characterization of clayrocks is needed in order to evaluate their feasibility for use as caprocks or host formations for greenhouse gas storage or nuclear waste disposal facilities, respectively. In this context, a method was developed for the measurement of CO₂ partial pressure in clayrock pore water. The PCO₂ was systematically acquired using core samples obtained from underground laboratories located at 4 locations in Europe. The isotope ratios (C, O) of the gas and of the carbonate minerals were also obtained. The stable isotope ratios limit the possible origins of the CO₂ to a thermodynamic equilibrium between aqueous solution species and the diagenetic carbonate minerals (calcite, dolomite), and a Mg-aluminosilicate.
