A Sedimentological and Micropaleontological Study of Quaternary Sections of Cores from the New Zealand Sector of the Southern Ocean
(The University of Waikato, 1998)The Southern Ocean lies between the Subtropical Front (STF) at about 45⁰S latitude and the continental landmass of Antarctica. It plays an important role in global climatic and oceanic circulation patterns, and is responsible ... -
A sedimentological study of three saline lakes in the Dry Valleys of Victoria Land, Antarctica
(University of Waikato, 1975)The Dry Valley region of Victoria Land is the largest ice-free area in Antarctica. Within the frigid arid environment of the Dry Valleys, where the mean annual air temperature is -20℃, there are several permanently ... -
Aspects of Neogene palaeoceanography in the southern Tasman Sea (DSDP site 593)
(The University of Waikato, 2002)Aspects of the Neogene palaeoceanographic history of the southern Tasman Sea are described in this thesis from DSDP Site 593 records of oxygen and carbon isotopes, and sediment texture and compositional data. Site 593 ... -
Comparative sedimentology and paleoecology of fossil giant oyster beds in some tertiary strata of New Zealand and Argentina
(The University of Waikato, 2010)Shell concentrations are useful indicators of relative sea-level changes, systems tracts, and depositional sequence and boundary surfaces. Shellbeds can equally act as archives of paleoenvironmental information and aid in ... -
Dredge spoil dispersion from an inner shelf dump-mound
(The University of Waikato, 1989)A study was undertaken on the dispersion of dredge spoil from a dump-mound on the inner shelf in 11-17 m water depth, 3 km offshore from Tauranga Harbour, New Zealand. Graphic and volumetric analysis of bathymetric changes ... -
Effects of catastrophic coastal landslides on the Te Angiangi Marine Reserve, Hawke's Bay, New Zealand
(University of Waikato, 2013)The Te Angiangi Marine Reserve protects 446 hectares of coastline considered to be representative of the nearshore marine environment of southern Hawke’s Bay. It was established in 1997, and since then has been an area ... -
Geology of Mangapanian (late pliocene) strata, Wanganui Basin: lithostratigraphy, paleontology and sequence stratigraphy
(The University of Waikato, 2002)Fourteen Mangapanian and early Nukumaruan (late Pliocene) cyclothems in Wanganui Basin have been studied, stratigraphically logged and geologically mapped in thirteen sections from west to east across the basin. The ... -
Investigating stratigraphic evidence for Antarctic glaciation in the greenhouse world of the Paleocene, eastern North Island, New Zealand
(University of Waikato, 2011)Early Paleogene (Paleocene-Eocene) climate was significantly warmer than today, with the poles generally considered to have been free of ice. These greenhouse conditions ended in the earliest Oligocene when the formation ... -
Late Holocene mud sedimentation and diagenesis in the Firth of Thames: Bentonites in the making
(University of Waikato, 1990)Late Holocene mud sedimentation in the southern Firth of Thames has been described from analysis of a number of shallow marine sediment cores. Three distinct lithofacies are distinguished on the basis of sediment texture ... -
Morphology and geochemistry of glauconite from the Te Kuiti Group, South Auckland region, New Zealand
(The University of Waikato, 1989)The late Eocene - Oligocene Te Kuiti Group comprises calcareous mudstone, calcareous sandstone and skeletal or sandy limestone formed in marginal marine to fully marine shelf settings. Glauconite is ubiquitous in all ... -
Nature, Distribution, Origin and Economics of Glauconite in Carbonate-Phosphate-Glauconite Surficial Deposits on Central Chatham Rise, Southwest Pacific
(University of Waikato, 2012)Chatham Rise is a broad, elongated submarine platform that extends 1100 km out into the Southwest Pacific off eastern South Island. The surficial sediments on the central portion of the Rise at depths of 200-500 m include ... -
New Zealand late miocene biostratigraphy and biochronology: Studies of planktic foraminifers and bolboforms at oceanic sites 593 and 1123, and selected onland sections
(The University of Waikato, 2004)Using high-resolution suites of core samples, including 940 samples from Deep Sea Drilling Project (DSDP) Site 593 in southern Tasman Sea off western New Zealand, and 353 samples from Ocean Drilling Program Site 1123 in ... -
Origin and occurrence of Antarctic lacustrine carbonates, with special reference to Lake Fryxell, Taylor Valley
(The University of Waikato, 1982)Lake Fryxell is a permanently ice-covered 19 m deep lake located 15m a.s.l. in the lower Taylor Valley, Antarctica (75° 35'S, 163° 35'E). The lake occupies the lowest part of the Fryxell drainage basin and is surrounded ... -
Paleoliquefaction in Late Pleistocene alluvial sediments in the Hauraki and Hamilton basins
(University of Waikato, 2015)Liquefaction susceptibility of the Late Pleistocene Hinuera Formation volcanogenic sediments is of interest to the engineering community as it is unclear whether materials of this age will still be prone to activation by ... -
Particulate fluxes in the subtropical convergence region and other marine environments of New Zealand
(The University of Waikato, 1997)The thesis was designed to address two themes: (1) sediment trap methods and technique development; and (2) oceanic sediment fluxes within the Chatham Rise-Subtropical Convergence ecosystem, east of New Zealand. Accordingly, ... -
Petrogenesis of Pliocene limestones in southern Hawke’s Bay, New Zealand: a contribution to unravelling the sequence stratigraphy and diagenetic pathways of cool-water shelf carbonate facies
(The University of Waikato, 2002)Among carbonate sedimentologists, it is now appreciated that shallow-marine carbonates are not restricted to warm-water tropical settings, but can also be produced on modern cool-water shelves outside tropical latitudes. ... -
Sedimentary facies and unconformity analysis of some Paleocene-Eocene sections, Marlborough and Campbell Island, New Zealand
(The University of Waikato, 2010)Throughout the Late Cretaceous to Eocene, sedimentation in gradually subsiding basins on the passive eastern margin of the micro-continent of Zealandia recorded climatic and paleoceanographic changes in a greenhouse world. ... -
Sedimentology and Petrology of Miocene Cold-Seep Carbonates in Southern Hawke's Bay: Geological Evidence for Past Seabed Hydrocarbon Seepage
(The University of Waikato, 2010)This study focuses on the five sites of Early Miocene aged cold seep carbonate deposits (Wanstead, Wilder Road, Haunui, Ugly Hill, and Ngawaka) in the southern East Coast Basin, North Island, New Zealand, which archive ... -
Sedimentology of Lake Taupo, Central North Island, New Zealand
(The University of Waikato, 1978)Lake Taupo, with an area of 616 km², is the largest of several lakes of volcano-tectonic origin in the Central Volcanic Region, North Island, New Zealand. In the past the lake has been affected by catastrophic volcanic ... -
