Geothermal energy involves transfer of heat from great
depth to the surface via the flow of hot fluid, which is
stored in subsurface reservoirs. This hot fluid also
transports metals to produce rich mineral deposits
containing gold and silver.
With 30 years of
experience, I provide advice to clients on how and where
geothermal and mineral resources occur. I specialize in
analyzing and interpreting chemical, mineralogical,
hydrological, lithological, geophysical, and other
geoscientific data associated with hot springs, wells,
volcanoes and gold-silver deposits. I also deliver short
courses (1-5 days), and I lead field excursions through the
Taupo Volcanic Zone and Coromandel Peninsula.
I split my time between
Auckland, New Zealand, and Golden, CO. I am the former
Director of the Geothermal Institute, University of Auckland.
I have worked on many geothermal systems and gold-silver
deposits in New Zealand and the Pacific Rim. I have
published over 70 scientific articles on a wide range of
topics dealing with geothermal systems, hot springs,
hydrothermal minerals, and the formation of epithermal
precious metal deposits.
I provide the best
geoscientific advice and interpretations of rocks, minerals,
and fluids in disovery and exploitation of geothermal and
mineral resources. |
