a Multi-box batch reactor modeling results for hyaloclastite at 250 °C and 25 MPa. The initial volumes of protolith and water are of 0.67 dm3 and 1 dm3, respectively. b Multi-box batch reactor modeling results for basalt at 250 °C and 25 MPa. The initial fluid/rock ratio (0.04 dm3 of basalt for 1 dm3 of water) is such as in a fracture from a 14- to 40-μm diameter
