The evolution of Lake Rotorua
The Rotorua volcanic centre (RVC) forms a well-defined topographic depression ≈ 21 km by 22 km in diameter that is located along, and partly delineates, a structural embayment in the western margin of the central TVZ.
The ...
Alpine fault pseudotachylytes
Pseudotachylytes produced during coseismic slip are ubiquitous within the rocks of the Alpine Fault zone, New Zealand. Pseudotachylytes from three principal host rocks are described and characterised from field and ...
Microstructural evolution under non-steady state deformation in mid-crustal ductile shear zones
Ductile shear zones localise tectonic stresses and accommodate plate motions in the middle to lower crust and mantle, and control the strength of much of the Earth. Despite a common assumption that ductile shear zones ...
How to be a Prehistoric Weatherman: Using n-alkanes as a Proxy for Holocene Climate and Hydrology, Southwest South Island, New Zealand
The latitudinal position and strength of the Southern Hemisphere westerly winds
(SHWW) plays a critical role in global CO2 air-sea flux and the distribution of
rainfall in the southern mid-latitudes. Strengthening and ...
Palaeomagnetism of Palaeogene strata from southern Zealandia: Implications for ice in the greenhouse
When did the first ice form on Antarctica? Large, stable ice sheets started to appear in the Oligocene, but there may have been earlier, transient Palaeocene glaciations which left only brief traces in the sedimentary ...
The Pounamu ultramafics : a study of metasomatism.
This thesis is an investigation of metasomatism developed at the contacts of the Pounamu Ultramafics in the Turiwhate Survey District.
The lithologies in the Turiwhate Survey District are characterized by a regional ...
Late Quaternary geology of Glenorchy district, Upper Lake Wakatipu
The Late Quaternary Geology of the Glenorchy District, Upper Lake Wakatipu was investigated in terms of geomorphology, sedimentary facies distribution and characteristics and Quaternary deformation.
Terraces that are ...
Geology of the southern part of the Longwood complex, Southland coast and Centre Island, New Zealand
This thesis combines the results of field work, petrographic studies and mineralogical and geochemical data from plutonic rocks of the southern part of the Longwood Complex, Southland, New Zealand.
Data presented here ...
Petrology and geochemistry of alkaline and granitoid intrusions, Pipecleaner Glacier region, Southern Victoria Land, Antarctica
In the Pipecleaner Glacier region, Southern Victoria Land metasediments of the Koettlitz Group have been intruded by nepheline syenites and granitoid plutons, of probable early Paleozoic age.
The Radian Ridge nepheline ...
