Thermal Liability of Hyaloclastite in the Krafla Geothermal Reservoir, Iceland: The Impact of Phyllosilicates on Permeability and Rock Strength
Table 1
Primary mineralogy identified by X-ray diffraction analysis of hyaloclastite that has experienced different thermal treatment temperatures. Note that the reduction in the smectite proportion causes the relative proportions of the other components to increase and that the presence of sideromelane is not quantified nor included in this analysis.
