Abstract The Abstract for this thesis Xenoliths of Otago Schist have been pyrometamorphosed upon entrainment within the Miocene basanite at Ram Rock, North Otago. This has resulted in recrystallisation from a greenschist facies mineral assemblage (T < 400°C) to a sanidinite facies assemblage (T > 900°C). Ram Rock xenoliths were analysed by scanning electron microscope electron dispersal spectrometry to characterise the mineralogy of xenoliths due to the very fine grain-size. The Otago Schist quartz-albite segregations have recrystallized to quartz with orthopyroxene coronas within rhyolitic glass. The micaceous segregations (muscovite, chlorite, garnet) have been completely replaced by olivine, spinel, plagioclase, cordierite, ilmenite, orthopyroxene and an alkali-rich mafic glass. The compositional segregations of the Otago Schist protolith are behaving as isolated blocks during pyrometamorphism, producing separate chemical domains of ultramafic and dacitic composition. Replacement textures indicate that the sanidinite facies minerals crystallised through two mechanisms: as the result of mineral reactions from the former greenschist facies minerals, or they nucleated within a melt and developed quench textures. The presence of quench textures and glass indicates that the xenoliths cooled rapidly to the glass transition temperature, likely through a combination of conductive cooling, minor convective cooling, and high viscosity inhibiting crystal growth. Metasomatic interaction with the host basanite has enriched the xenolith in 2.3 wt% CaO, 0.6 wt% K2O, and 4.3 wt% SiO2 with minor enrichment of FeO, TiO2, and Na2O within minerals on the basalt-xenolith interface. Inferred mineral reactions give constraints on temperatures reached, with chlorite breakdown occurring at 870°C and muscovite partial melting and complete removal at 900-950°C. Quantitative geothermometry gives temperatures of ~960-1030°C for glass, while the more suitable orthopyroxeneliquid and plagioclase-liquid geothermometers give 940-980°C, allowing more precise constraints on temperatures reached.

Abstract The Abstract for this thesis Tungsten mineralisation within the Otago Schist is hosted by hydrothermal quartz veins that formed close to the brittle-ductile transition zone. The Otago Schist Belt hosts numerous orogenic gold deposits, including the Macraes mine, a number of which also host the tungsten ore mineral scheelite. Despite the strategic importance of tungsten, no commercial mining of scheelite in Otago has occurred since the 1960s, and the Macraes operation does not recover tungsten despite mining tungsten ore. This study examines the spatial and temporal relationships between gold and tungsten from a microscopic up to a deposit scale, focusing on the Macraes deposit and applying the findings to the wider Otago region. Understanding this relationship is essential for modelling and extracting tungsten in Otago, and in the exploration for new deposits. Macraes’ tungsten is predominantly found within mineralised quartz veins, although a subordinate phase of disseminated scheelite and a remobilised phase are also observed. Ductile microstructures and the cross-cutting relationships observed within the veins suggest that the main phase of tungsten mineralisation occurred early in the development of the deposit. The style of tungsten mineralisation contrasts strongly with that of gold at Macraes, which is disseminated throughout the pervasively altered wall-rock, and which is contemporaneous with both brittle and ductile structures. This relationship is echoed throughout the deposits in Otago: tungsten mineralisation is found within veins that formed at depth within the crust while gold is found associated with both deep and shallower structures. The extent of tungsten mineralisation was determined in a section of the Macraes mine using Portable XRF (pXRF). This approach identified a 200 m by 80 m pod of tungsten mineralisation coinciding with a jog in a mineralised shear, suggesting that mineralisation is associated with the opening of large-scale dilational sites. Evidence from the Nd and Sr isotope signatures of the Macraes scheelites suggest that the source mineralisation at Macraes was the schists of the Torlesse Terrane. The data favours a model of a metamorphic source of mineralisation, in which dewatering of the schist under amphibolite facies conditions produces hydrothermal fluid, which leaches metals from the schists as it ascends through the crust.

Abstract The Abstract for this thesis Ultramafic xenoliths represent fragments of the upper mantle brought to the Earth’s surface during mafic volcanism and offer a rare opportunity to study the mineralogy, textures and processes associated with the mantle. The present study was based at Kattothyrst, a remnant volcanic neck in the Kakanui Range of north Otago. The host alkaline basanite outcrop of the Waipiata Volcanic Group encloses an abundance of mantle xenoliths of spinel lherzolite, harzburgite, dunite and wehrlite composition whose mineralogy comprises combinations of olivine, Cr-enstatite ± Cr-diopside ± spinel. Reconnaissance electron backscatter diffraction patterns suggest that at least one of the samples has a high temperature fabric and strong lattice preferred orientation. Rare samples have been found to contain modal apatite, a metasomatic mineral introduced to the mantle beneath Otago by a mobile fluid or melt which has undergone incompatible element exchange with the surrounding mantle. Thermobarometry of the xenoliths yielded relatively consistent temperatures of crystallisation of 878-990°C (for pressures of between 10 and 20 Kb). Chemical LA-ICP-MS analyses of clinopyroxene grains show the whole suite has been enriched in light rare earth elements (LREE). Harzburgites are extensively melt depleted and show M (middle) REE and H (heavy) REE depletion trends that probably pre-date LREE enrichment. The trace element study, coupled with the fluid inclusion and microprobe analysis, indicates the metasomatic agent was probably rich in fluorine as well as LREE, Ca and P. The metasomatic agent is inferred to have most likely been a carbonatite melt. The timing of metasomatism is not known but must predate volcanism of about 16 Ma. The temperature differences between specimens from Kattothyrst and nearby Waipiata Volcanics enable a broad Miocene mantle stratigraphy to be constructed beneath the Kakanui Range. Given the geochemical evidence for significant melt depletion, the mantle history recorded probably represents old Gondwana margin processes.

Abstract The Abstract for this thesis Early Miocene (~23-16 Ma) rock units—the Mount Harris Formation (Otaian – Altonian) and Gee Greensand (basal Otaian)—at Awamoa Beach, North Otago, preserve fossils of extinct Cetacea. The Early Miocene is a significant time in cetacean history as the interval where some archaic whales declined and the bulk of modern cetaceans began to dominate the oceans. Awamoa Beach—historically important as the locality from which the first New Zealand fossil cetacean was described—became accessible as a fossil site in 1999. Thus far, it has produced a diverse assemblage of Early Miocene whale fossils which expands the patchy global record of Early Miocene cetacean localities. This project records four fossil cetacean skulls and some post-cranial material recovered from Awamoa Beach within the last decade. Fieldwork as part of this thesis was precluded by a thick layer of shingle that has overlain Awamoa Beach units since mid 2008, so that research concentrated on fossils already collected from Awamoa Beach (curated in the Geology Museum, University of Otago); some are documented here. I used physical and chemical preparation methods to remove matrix from some of the fossils. Subsequently, I have identified four odontocetes and discussed their phylogenetic relationships with previously documented odontocetes. Among the recovered cetacean fossils of Awamoa Beach, one partial skull and its associated post-cranial material, OU22466, most likely represents the short-jawed shark-toothed dolphin, Prosqualodon cf. davidis, hitherto known only from Australia. This is the first firm report of a Prosqualodon skull from New Zealand. Specimen OU22672 likely represents an early member of Delphinoidea. The interconnected sinus fossae of the basicranium and pronounced asymmetry of the skull suggest that it is a specialized odontocete that is phylogenetically related closely to delphinids. Poor preservation precludes firm taxonomic placement. The skull was found as float on Awamoa Beach so an experiment—one of the first of its kind from New Zealand—was designed and conducted to liberate foraminifera from the matrix of the skull to date the specimen. Although the experiment did not produce diagnostic foraminifera that could date the skull, it identified procedures for liberating foraminifera that could prove useful to future studies. Another important skull is OU22670, a new genus and species of the Pomatodelphininae which is the sister taxon of extant Platanista, the river dolphin of the Indian subcontinent. The results of a cladistic analysis suggest that OU22670 is the sister taxon of Prepomatodelphis from the late Early Miocene. Thus, OU22670 extends the global fossil record of Platanistidae to earlier in the Miocene and suggests that Platanistidae did not originate in the northern Atlantic Ocean as previously believed. Additionally, the highly derived characters of OU22670 indicate that it is more specialized than Prepomatodelphis. OU22465 is an enigmatic specimen that has a ‚rostral bulge‛, a feature not documented from any other odontocete taxon. This feature is somewhat similar to the large maxillary crests of Squalodelphinidae and Platanistidae. This incomplete skull is documented as Odontoceti: Platanistoidea incertae sedis. The findings of this project suggest that Awamoa Beach could be regarded as one of the globally few significant Early Miocene cetacean fossil localities.

Abstract The Abstract for this thesis The Tapui Glauconitic Sandstone is a marine transgressive unit which was deposited in a mid-shelf environment on the east coast of the New Zealand landmass during the mid-Eocene. Sedimentary structures in the form of storm generated hummocky cross-stratification and the presence of exotic macrofauna, indicate deposition below fair-weather wave base and above storm-wave base. Strong concentrations of glaucony near the base of the sandstone indicate it was forming insitu in the early stages of the transgression. Up section terrigenous input increases and the amount of glaucony decreases. The glaucony is disseminated throughout the upper part of the formation and is allocthonous, evident by the degree of mechanical abrasion the grains have undergone. The Tapui Glauconitic Sandstone contains approximately one percent heavy detrital minerals. The heavy minerals are predominantly derived from a granitic terrane, 300 km to the south of the depositional environment. Heavy minerals with a granitic derivation include spessartine rich garnet, schorl tourmaline, zinc spinel (gahnite), zircon and rutile (type A). High rank metamorphic minerals sillimanite, corundum?, kyanite and staurolite, indicate a southern ultimate source for some heavy minerals in the sandstone. There is an Otago Schist and underlying Papakaio Formation proximate source for dravitic tourmaline, gold, zircon, anatase? and magnetite in the sandstone. Longshore and bottom currents flowing in a northerly direction up the east coast of the New Zealand land mass in the Bortonian, deposited the heavy minerals in the Tapui Glauconitic Sandstone. Contemporaneously rivers on the adjacent landmass, deposited locally derived heavy minerals in the shelf environment. Abundant clays derived from thorough weathering of the basement, and the presence of warm water taxa in the sandstone, indicate a sub-tropical to tropical climate during the Bortonian. Magma of tholeiitic composition fed by vents in the ocean floor, intruded the Tapui Glauconitic Sandstone between the mid-Eocene and late-Eocene. Where Large volumes of magma intruded, it cooled slowly forming columnar jointed sills. Less voluminous amounts of magma resulted in glassy pillow lavas which are high strontium, indicating intrusion in to sediment saturated in sea water.

Abstract The Abstract for this thesis A distinctive unconformity is present in many of the shallow water earliest Miocene sequences of North Otago and South Canterbury, between the Otekaike Limestone and the overlying sediments. However, this feature is not universally developed throughout this region. Sequences in eastern Canterbury and western Otago are commonly continuous throughout this period. Possibly correlative unconformities are seen in comparable late Oligocene to early Miocene sequences in South Otago, North Canterbury, Westland, and Nelson, suggesting a regional scale of development for this feature. Where it is well developed, particularly in coastal areas of North Otago and around Blands Bluff in Canterbury, this unconformity is an irregular, extensively solution-affected surface showing relief of up to 1 m or more at an outcrop scale. Its character is inferred to suggest formation by exposure of the Otekaike Limestone to subaerial erosion. Possible terrestrial exposure is also supported by the character of the sediments directly overlying this unconformity. These commonly include well rounded reworked local and exotically derived clasts up to 30 cm in diameter, which in places (most notably at Hutchinsons Quarry in Oamaru) reach high concentrations, forming distinctive basal conglomerates. Detailed microfaunal dating constrains the development of this unconformity to the mid to upper Waitakian - the Globigerina woodi woodi and Globigerina woodi connecta zones of Jenkins (1971). This interval also coincides with major sedimentological changes throughout the North Otago and South Canterbury regions- even in sections where no intra-Waitakian unconformity is developed. The dominantly bioclastic sediments of the Otekaike Limestone are replaced at this time by more glaucony and/or terrigenous rich formations such as the Mount Harris Formation and Gee Greens and. These changes in the sedimentary regime of the region are attributed primarily to an initiation of tectonism in the provenance region of the sediments at this time. Evidence for active faulting contemporaneous with the development of this intra-Waitakian unconformity is seen at Gees Bay on the North Otago coast, and is also tentatively inferred for the Otiake region. However, tectonism probably had only a peripheral influence on the development of this unconformity in most areas. Rather, the extensive geographic distribution of this erosion surface, combined with the apparent simultaneity of its development everywhere it is exposed suggests that this unconformity is primarily the result of a eustatic fall in sea level. This suggestion is further supported by an apparent correlation between the mid to upper Waitakian age inferred for this unconformity and a global sea level drop of approximately 40 m identified by Haq et al. (1987). Department The department where the student is studying primarily. Geology Named locality Named locality describing the field area location.

Abstract The Abstract for this thesis This dissertation reviews the taxonomic status, stratigraphic and geographic distributions of the Cenozoic and Recent rhynchonellide brachiopods of New Zealand and describes their morphological variation and ecology (Part I). This is followed by a general account of the systematics, distribution, and paleoecological and biogeographic significance of the Paleocene-Early Oligocene brachiopod faunas of which the rhynchonellides form an integral part (Part II). A single species of the endemic genus Aetheia, A. gualteri, occurs in a variety of sediments ranging in age from Mid Eocene to Early Miocene. This smooth, trigonal, probably free-living brachiopod inhabited a shallow shelf environment and specimens were often bored by gastropods and sponges, and encrusted by tubeworms and bryozoans. The black ribbed Notosaria nigricans is widely distributed in New Zealand shelf waters especially on rocky or shelly substrates from intertidal depths to about 200 m. A new subspecies, N. n. reinga is recognised from deeper water (80-800 m) off northern New Zealand. N. nigricans has a long, nearly continuous fossil record extending to the Mid Miocene. A close relative, the spinose N. antipoda, formerly placed in the genus Tegulorhynchia, ranged from the Early Oligocene to Early Miocene. N. nigricans forms part of a characteristic hard-bottom community dominated by sessile filter-feeders such as other brachiopods, bivalves, barnacles, bryozoans, sponges, ascidians and tubeworms. Adult brachiopod shells are often asymmetric or deformed due to the crowded mode of life, are extensively covered with epifaunal organisms including conspecific and other brachiopods, and the normal population structure comprises all size ranges from juvenile to adult. The costellate, usually spinose genus, Tegulorhynchia, was represented in New Zealand by the type species T. squamosa (syn. T. depressa and T. masoni) from the Paleocene to Early Miocene-, and by T. sublaevis in the Oligocene. A single species, T. doederleini, lives today in Indo-Pacific waters. Two species, T. aoeZata and T. thomsoni from the Oligocene-Miocene of Australia are described. A further species, T. imbriaata, occurs in the Oligocene of Antarctica. Two rhynchonellide genera new to New Zealand are reported. The semicostate Probozarina ahathamensis n.sp. is widespread in Paleocene-Eocene limestones and calcareous tuffs on the Chatham Islands. A few specimens of a related smooth rhynchonellide with a twisted commissure from a Mid Miocene horizon in Taranaki are placed in the genus Streptaria. Aetheia, Tegulorhynahia and Probolarina are important components of the rich Paleocene-Early Oligocene brachiopod faunas of New Zealand. At least 14 genera and 20 species including several new species, Crania waiareka, Argyrotheca oamarutica and ?TerebrateZla rekohu, are described and figured, many for the first time. A number of mainland genera, notably Lingula, TeguZorhynchia, Argyrotheca and Thecidellina, are recorded from Paleocene-Eocene localities, mostly new, on Chatham and Pitt Islands. The stratigraphic and geographic ranges of virtually all other species, especially those of Late Eocene-Early Oligocene age from the Oamaru region are extended. Most of the brachiopods occur in bioclastic limestones, calcareous tuffs, or greensands, usually in company with large numbers of other sessile filter-feeders which require a hard substrate and relatively shallow clear shelf conditions with little or no terrigenous sedimentation. The brachiopods represent several different life habits - the inarticulate Lingula burrowed in interto subtidal fine sandy sediment; the other inarticulate, Crania, and the minute Thecidellina, were cemented to hard microsubstrates such as cobbles or bryozoan colonies; Aetheia and Stethothyris were probably free-living; Terebratulina may have anchored its pedicle to sediment particles; and the remainder were attached to hard substrates. Many of the brachiopods, especially Lingula, Argyrotheca, Campages and Thecidellina, are indicative of sub-tropical to tropical sea temperatures, and their presence in Paleogene rocks in New Zealand and elsewhere supports the hypothesis of warm global temperatures in the Early Cenozoic.
