Applied Geology of Wellington Rocks for Aggregate and Concrete

Rowe, Graham Hamilton (Victoria University of Wellington, 1980)

This study was initiated to examine geological aspects of Wellington greywacke-suite rocks in relation to their end use as an engineering material - aggregate, particularly for concrete. An attempt has been made to map (at ...
Crystal Forensics of Historical Lava Flows from Mt Ngauruhoe

Barton, Sophie Jan (Victoria University of Wellington, 2011)

Mt Ngauruhoe is a 900 m high andesitic cone constructed over the last 2500 yr, and is the youngest cone of the Tongariro Massif. It was previously one of the most continuously active volcanoes in New Zealand, with ash ...
Crystal Specific Constraints on Subvolcanic Processes Preceding Eruptions at Mt Taranaki, New Zealand

Martin, Sarah Alicia (Victoria University of Wellington, 2012)

Andesitic magmas are the product of a complex interplay of processes including fractional crystallisation, crystal accumulation, magma mixing and crustal assimilation. Recent studies have suggested that andesitic rocks ...
Fluid Inclusions, Stable Isotopes and Geochemistry of Porphyry Copper and Epithermal Vein Deposits of the Hauraki Gold - Silver Province, New Zealand

Christie, Anthony Barry (Victoria University of Wellington, 1982)

Tertiary epithermal Au-Ag-Pb-Zn-Cu vein, and porphyry copper deposits occur in the Hauraki Province. The epithermal deposits were extensively mined for gold and silver in the late 1800's, and early 1900's and produced ...
Lithospheric Xenoliths from the Marie Byrd Land Volcanic Province, West Antarctica

Wysoczanski, Richard J (Victoria University of Wellington, 1993)

Studies of the Earths lithosphere, and particularly the lower crust, have in the past relied on geophysical methods, and on geochemical studies of granulite terrains exposed at the surface. Geophysical studies can not ...
Metamorphism and the P-T History of Alpine Schist from the Newton Range, Southern Alps, New Zealand

Murphy, Dave B (Victoria University of Wellington, 2010)

Metamorphic rocks have the potential to record in their mineral assemblages, mineral compositional zoning, and textures, information about geological changes and processes that occur during tectonic events. Interpretations ...
Micro-Analytical Studies of the Petrogenesis of Silicic Arc Magmas in the Taupo Volcanic Zone and Southern Kermadec Arc, New Zealand

Saunders, Katharine Emma (Victoria University of Wellington, 2009)

The petrogenesis of silicic arc magmas is controversial with end-member models of fractional crystallisation and crustal anatexis having been invoked. A prime example of this is the archetypical continental Taupo Volcanic ...
Petrochemical and Sr isotopic studies of lavas and xenoliths from Tongariro volcanic centre : implications for crustal contamination of calc-alkaline magmas

Graham, Ian J (Victoria University of Wellington, 1985)

Petrogenesis of Tongariro Volcanic Centre lavas, particularly those from Mount Ruapehu and nearby vents, is investigated through a detailed petrochemical and Sr isotope study. The importance and nature of crustal contamination ...
The Petrology and Petrochemistry of Andesite and Dacite Volcanoes in Eastern Bay of Plenty, New Zealand

Duncan, Andrew Rae (Victoria University of Wellington, 1970)

The volcanic rocks of Edgecumbe, Whale Island, White Island and Manawahe are andesites and dacites, which are collectively termed the Bay of Plenty volcanics. Edgecumbe is a comparatively young volcano, being active between ...
The Recent Carbonate Sediments of Palmyra Atoll, Northern Line Islands, Central Pacific Ocean

Clark, Oscar (Victoria University of Wellington, 2008)

Palmyra Atoll is an isolated carbonate reef system located approximately 1600 km south of Hawaii in the northern Line Islands, central Pacific Ocean. Sediment samples from the lagoons and tidal zones were analyzed for ...
Some Studies of New Zealand Quaternary Pyroclastic Rocks

Kohn, Barry Paul (Victoria University of Wellington, 1973)

The development of volcanic "ash" studies in New Zealand can be traced through three broad periods (Jeune 1970). During the late 19th century the extensive pumice deposits surrounding Lake Taupo received considerable comment ...
Structure and Petrology of the Red Hill Complex, Nelson

Walcott, Richard Irving (Victoria University of Wellington, 1965)

The Red Hill Complex is an essentially concordant ultramafic body enclosed in Upper Paleozoic flysch facies sediments which include Pelorus Group (oldest), Lee River Group and Maitai Group. The Pelorus Group contains rare ...
The Volcano‐Tectonic Evolution of the Macquarie Ridge Complex, Australia‐Pacific Plate Boundary South of New Zealand

Conway, Christopher Edward (Victoria University of Wellington, 2011)

The Macquarie Ridge Complex (MRC) forms the submarine expression of the Australia‐Pacific plate boundary south of New Zealand, comprising a rugged bathymetry made up of numerous seamounts along its length. Tectonic ...
