Quantifying the role of hydrothermal alteration in creating geothermal and epithermal mineral resources: The Ohakuri ignimbrite (Taupō Volcanic Zone, New Zealand)

• Silicification reduces matrix permeability by up to four orders of magnitude. • Alteration to clay only reduces matrix permeability by up to an order of magnitude. • Only silicification increases propensity for permeability enhancing fracture formation. • Silicified rock-masses (reservoir) are mor...
