Mapping lithology and hydrothermal alteration in geothermal systems using portable X-ray fluorescence (pXRF): A case study from the Tauhara geothermal system, Taupo Volcanic Zone
(Elsevier, 2016)Portable x-ray fluorescence (pXRF) analyzers are widely used in the environmental and mineral exploration fields. pXRF analyzers can rapidly and inexpensively provide chemical concentrations on a variety of elements, often ... -
Offsetting of CO₂ emissions by air capture in mine tailings at the Mount Keith Nickel Mine, Western Australia: Rates, controls and prospects for carbon neutral mining
(Elsevier, 2014)The hydrated Mg-carbonate mineral, hydromagnesite [Mg₅(CO₃)₄(OH)₂•4H₂O], precipitates within mine tailings at the Mount Keith Nickel Mine, Western Australia as a direct result of mining operations. We have used quantitative ... -
Pyrite geochemistry and textures in the epithermal Au-Ag mineralisation at Waihi
(2016)The Waihi epithermal system is a low sulphidation epithermal system that hosts one of the largest high grade ore deposits in the Southern Hemisphere. The use of petrographic and EPMA analyses demonstrate there are distinctive ... -
Quantitative mineral mapping of drill core surfaces II: long-wave infrared mineral characterization using μXRF and machine learning
(Society of Economic Geologists, 2020)Long-wave infrared (LWIR) spectra can be interpreted using a Random Forest machine learning approach to predict mineral species and abundances. In this study, hydrothermally altered carbonate rock core samples from the ... -

Measuring the temperature response of soil respiration from two distinct carbon pools in soil.
(The University of Waikato, 2020)As soils contain a large store of terrestrial carbon, understanding the dynamics and stability of this important carbon reserve and how it may change with regards to future changes in temperature is of global interest. It ... -
Emerging stable isotope techniques in hydrothermal research: new methods applied to carbonates and hydrous minerals in ore deposits and geothermal fields
(The University of Waikato, 2019)Over the last 70 years, stable isotopes have provided critical insight into the processes governing transfer of mass and energy through geologic systems. Significantly, isotopic signals in minerals reflect conditions of ... -
Texture and chemistry of pyrite from the Waihi epithermal system, Hauraki Goldfield, New Zealand
(University of Waikato, 2017)The Waihi epithermal system is a low sulfidation epithermal system that hosts one of the largest epithermal Au-Ag deposits in the Southern Hemisphere. Various sulfide minerals are present within the system, including pyrite ... -
Andesite volcanic facies and hydrothermal alteration in the subsurface peripheral to existing Waihi mine workings
(University of Waikato, 2015)The Waihi vein system is an andesite-hosted epithermal Au-Ag deposit comprising a series of veins located in the southern Hauraki Goldfield, New Zealand. It includes the Martha Mine which is the largest gold producer in ... -
Carbonate Alteration of the Sams Creek Gold Deposit
(University of Waikato, 2016)Located near Upper Takaka, NW Nelson, the Sams Creek Gold Deposit is host to significant gold mineralisation, which has been extensively explored since being first discovered in 1974 by CRA exploration. The gold mineralisation, ...
