Johnstone, Roy David (Thesis, Master of Science, 1980)

Ata is the most southerly island in a chain of young volcanic islands in the Tonga Group lying to the west of the Tonga trench. It is presently inactive and now consists of a small remnant (1.8 km2) of a large composite ...

Glacigenic systems in the Upper Clutha valley in Central Otago, New Zealand

Brooks, Peter Kenneth (Thesis, Master of Science, 1986)

This report describes the glacigenic stratigraphy from the Upper Clutha Valley in Central Otago. The deposits from seven glacial advances are described and modelled on a wet based glacier. Stratigraphic classification of ...

Stratigraphy, tectonics, and provenance of rocks in the Wether Hill area, Western Southland

Willsman, Andrew (Thesis, Bachelor of Science with Honours, 1991)

A terrane boundary was mapped between the Murihiku Supergroup and the Takitimu Group in the Wether Hill area, Western Southland. The two terranes (Murihiku and Brook Street) are juxtaposed along the gently eastward-dipping ...

The geology of the Eastern Saddle Road area, Manawatu, N.I., N.Z.

Grammer, Terrence Ronald (Thesis, Bachelor of Science with Honours, 1971)

A segment of the Brookstreet terrain (Coombs et. al., 1976) is described from the Bluff Peninsula, Southlando The basement rocks include Lower-Permian volcanogenic sediments and dykes of the Greenhills Group with interbedded ...

Murihiku lithology and lithostratigraphy across Beaumont and Ardcross stations, southern Wairaki hills

Gass, Sarah Maree (Thesis, Bachelor of Science with Honours, 1998)

The area mapped (18kni2), crosses the boundary between the Brook Street terrane of Permian - Early Jurassic age and the Murihiku terrane of Triassic, north of Ohai in western Southland. This study focused on the lithology ...

The geology of Flat Hill-Ocean Beach, Bluff Peninsula

Elder, Damon Jon (Thesis, Bachelor of Science with Honours, 1994)

In the Bluff area lower green schist facies Greenhills Group rocks of the Brook Street terrane derived from a Permian volcanic arc have been intruded by igneous bodies inducing contact metamorphism. Facies of contact ...

The geology of Bluff Hill, Southland, New Zealand.

Bosel, Craig A. (Thesis, Bachelor of Science with Honours, 1981)

The mineralogy and structure of two gabbronorite intrusions forming Bluff Hill, is described. They intrude volcanogenic metasediments of the Greenhills Group and together comprise a segment of Brook Street terrane (Coombs ...

Geology of the Dusky Sound area, Fiordland, with emphasis on the structural-metamorphic development of some porphyroblastic staurolite pelites.

Ward, Christopher Mark (Thesis, PhD, 1984)

A geological map of the Dusky Sound area (~ 700 km2) is presented at a scale of 1:59 000. The North and South Dusky areas are of generally contrasting character and are described separately. North Dusky is dominated by ...

Plutonic and metamorphic rocks in the Victoria range segment of the Karamea batholith, Southwest Nelson, New Zealand.

Tulloch, Andrew James (Thesis, PhD, 1979)

The Karamea Batholith forms part of the zone of calc-alkaline orogenic batholiths which rim the Pacific continental margin. In the vicinity of the Victoria Range the batholith is flanked by quartz-rich sandstones, and ...

Cenozoic fossil wood of the southern South Island, New Zealand

Vanner, Mathew Richard (Thesis, Master of Science, 2017)

Fossil wood collected from 14 sites in the southern South Island, New Zealand was identified to family or genus level. These sites included two of Eocene age: Waihao River (Runangan to early Whaingaroan) and Pikopiko ...

Characterisation and bioavailability of metals in historic mine wastes, Waiuta, Westland

McLachlan, Christine Jane (Thesis, Master of Science, 2017)

New Zealand has a long history of mining which has left a legacy of abandoned, contaminated mine sites with no accountability to the previous mining companies. The Prohibition Gold Mine, near Waiuta, Westland, was operational ...

Acoustic Investigations of Geologic Hazards and Seismic Processing Off the Coast of Otago, New Zealand

Holt, Andrew Arnold (Thesis, Master of Science, 2017)

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 ...

Electrical properties of schist and mylonite from the South Island, New Zealand: Exploring the source of the Southern Alps Anomalous Conductor

Kluge, Katherine (Thesis, Master of Science, 2017)

The Southern Alps Electrical Conductor (SAC), identified from magnetotelluric surveys of the South Island Geophysical Transect (SIGHT) in the South Island, New Zealand, has high electrical conductivity relative to surrounding ...

Paleoseismology of the Akatore Fault, East Otago

Taylor-Silva, Briar (Thesis, Master of Science, 2017)

My thesis documents the first-ever paleoseismic trench investigation of the Akatore Fault, which has long been considered the most active fault to exist near Dunedin City. Two trenches were excavated across the fault in ...

Granular Dynamics in Shallow Earthquake Slip Zones: Insights from Microstructural Analysis of Clast-Cortex Aggregate Grains

Crookbain, Kieran (Thesis, Master of Science, 2017)

Understanding the dynamics of shallow earthquake rupture and coseismic slip in carbonate-dominated fault zones is exceptionally important in many areas worldwide. Although constraints are available from rock mechanics ...

Validation of ground motion simulations using precarious rocks

Bowie, Elliot (Thesis, Master of Science, 2017)

Southern California Earthquake Center (SCEC) have developed the Broadband Platform (BBP) that computes 0-100 Hz seismograms for historical and scenario earthquakes using several ground motion simulation methods. Simulating ...

The Waitaki Canyon - An investigation of the Late Quaternary development of a shelf-indenting submarine canyon using high-resolution boomer seismic data

Abbey, Cameron James (Thesis, Master of Science, 2017)

Submarine canyons are well documented, both around New Zealand and globally, but questions remain around the processes involved in their formation and evolution as well as around how their morphology reflects their ...

Seismic characterisation of hydrate and shallow gas systems associated with active margin sediments and structures in the Pegasus Basin, Hikurangi Margin, New Zealand

Fraser, Douglas (Thesis, Doctor of Philosophy, 2017)

The Pegasus Basin off the east coast of New Zealand's North Island is a frontier basin that hosts a large gas hydrate province. The basin has a large amount of faulting, which has lead to the creation of many interesting ...

The damage zone of New Zealand's Alpine Fault

Williams, Jack Nicholas (Thesis, Doctor of Philosophy, 2017)

The dynamic propagation of an earthquake rupture will generate inelastic deformation within its surrounding medium, culminating in the development of a fault damage zone. These are heavily fractured volumes of rock that ...

Evolution and dynamics of a monogenetic volcanic complex in the southern Hopi Buttes Volcanic Field (AZ, US): magma diversion and fragmentation processes at the Jagged Rocks Complex

Re, Giuseppe (Thesis, Doctor of Philosophy, 2017)

Many populated areas in the world (e.g., Flagstaff, AZ; Auckland, NZ; Mexico City, MEX) lie within active monogenetic volcanic fields that typically contain small volcanic cones and explosive maar craters formed over the ...
