2015-10-1  Kinetic experiments of basalt–water (400 °C) using flow through backed bed reactor.. The release rates for various metals of basalt to aqueous solutions are quite different. • The release rates of Si reach a maximum at 300 °C (at 350 °C in NaCl-H 2 O).. Alteration zoning is caused by the variation of release rate.
