  1. DIW stands for deionized water. Cox stands for Callovo-Oxfordian claystone. S, CF stand for static, or continuous flow, respectively. The pH is given at 90 °C ((c) = calculated or estimated from data obtained at room temperature) and corresponds to a mean value at the time when rr was calculated. rr is given in g.m−2.d−1. Uncertainty on rr is estimated at 0.2 log units.
