Gravity Modelling of Groundwater Aquifers in South Dunedin, New Zealand
The aquifer of South Dunedin, set within low-lying coastal sediments that infill a paleovalley, needs to be understood better to evaluate how the hydrogeological system responds to large influxes of surface water from the ...
An investigation into the characterisation of seismic traces: optimising shear wave signals with source type, orientation and survey geometry
Seismic surveys are used to create visual representations of subsurface geology by detecting the reflections and refractions of seismic waves. In most cases, the seismic wave of interest is the P-wave, the easiest wave to ...
A Study Of Plant Fossils From Landslip Hill Silcrete
The Miocene Landslip Hill silcrete from Southland, southern New Zealand is a fluvial deposit consisting of quartz sand cemented by amorphous silica, in which numerous randomly oriented three-dimensional plant fossils are ...
High resolution lacustrine records of Late Holocene climate change from southern New Zealand
New Zealand freshwater ecosystems are directly impacted by temperature and precipitation variations controlled by the strength and position of the Southern Hemisphere Westerly Winds. Understanding westerly wind controls ...
The effects of graphite and porosity on the mechanics of the Alpine Fault, New Zealand
New Zealand’s Alpine Fault is a major crustal-scale structure that accommodates around 75% of relative Australian-Pacific plate motion. This active transform fault ruptures in a large earthquake every 291 ± 23 years, most ...
Acoustic Investigations of Geologic Hazards and Seismic Processing Off the Coast of Otago, New Zealand
What is the current condition of geologic hazards off the coast of Dunedin, New Zealand? Both the Akatore and Green Island Faults are thought to be active in this location. With earthquake events around Christchurch, New ...
Geology and Paleontology of Foulden Maar, Otago, New Zealand
Foulden Maar is a latest Oligocene–earliest Miocene maar–diatreme volcano located in a vent cluster of the monogenetic Waipiata Volcanic Field in Otago, New Zealand. The present–day erosion level exposes a 1000 x 650 m ...
Linking Shallow and Deep Features on the Shelf East and West of Stewart Island
The sedimentary basins that have developed to the east and west of Stewart Island are linked through similar tectonic and depositional processes during their formation. The sediment supply and tectonic rifting phases are ...
The Anita Peridotite: A Study of Subcontinental Lithospheric Mantle Emplaced into the Lower Crust of Northern Fiordland, New Zealand
The Anita Peridotite is an orogenic peridotite emplaced within a lower crustal ductile shear zone in Fiordland, south-western New Zealand. The unit has undergone little alteration and may preserve primary mantle mineralogy ...
Sedimentology, paleoecology and paleogeography of the shallow marine Chatton Formation, southern New Zealand
Chatton Formation, is a late Oligocene (Duntroonian (27.3–25.2 Ma) to Waitakian (25.2–21.7 Ma)) unit comprising fossiliferous shallow marine sandstones, sandy siltstones, greensands, grainstones and conglomerates. The ...
