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 ... -
Recognising cryptic alteration surrounding the Mount Isa Copper Deposits: Implications for controls on fluid flow, and mineral exploration
(The University of Waikato, 2020)This study investigated cryptic alteration haloes associated with copper mineralisation at Mount Isa, Northwest Queensland, Australia. New insights from hydrothermal alteration were used to constrain aspects of hydrothermal ... -
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, ... -
Using a tephrostratigraphic framework to determine the past 40,000 yrs of fault rupture and paleohydrothermal activity on the east strand of the Whirinaki Fault, Ngakuru Graben, central Taupo Volcanic Zone
(University of Waikato, 2016)The Ngakuru Graben in the central Taupo Volcanic Zone, North Island, New Zealand, is largely thermally inactive, but several fossil geothermal systems have been mapped throughout the area parallel to the Whirinaki Fault ... -
Identifying Mineralogical and Geochemical Vectors towards the Epithermal Au-Ag Correnso Mine, Waihi
(University of Waikato, 2015)The Au-Ag rich Correnso vein is a low sulphidation epithermal deposit located east of Waihi and is named after the clay mineral corrensite. Hydrothermally altered andesitic and dacitic host rocks of the Waipupu Formation, ...
