Thermal Liability of Hyaloclastite in the Krafla Geothermal Reservoir, Iceland: The Impact of Phyllosilicates on Permeability and Rock Strength

<div>The effect of loading on permeability and porosity. (a) Water permeability evolution against effective pressure. Samples exhibit a large range of responses and degree of scatter for a given TT. (b) Pore space collapse associated with increased effective pressure. Change in porosity is measured from ~3.5 effective pressure.</div>
