Quantifying the role of hydrothermal alteration in creating geothermal and epithermal mineral resources: The Ohakuri ignimbrite (Taupō Volcanic Zone, New Zealand)
Hydrothermal fluids can alter the chemical and physical properties of the materials through
which they pass and can therefore modify the efficiency of fluid circulation. The role of …

The influence of pore geometry and orientation on the strength and stiffness of porous rock
The geometry of voids in porous rock falls between two end-members: very low aspect ratio
(the ratio of the minor to the major axis) microcracks and perfectly spherical pores with an …
