Abstract
The Abstract for this thesis
The provenance of the Murihiku Terrane has been investigated using petrography, geochemistry and geochronology on igneous, mainly plutonic, clasts found in rare conglomerates along the Catlins Coast, southeastern New Zealand. Late Triassic (Oretian) conglomerates at Roaring Bay and Middle Jurassic (Temaikan) conglomerates at False Islet, Waikawa, and Slope Point have been studied in detail. These are generally polymict, poorly sorted, and pebble to cobble (uncommonly boulder) grade. The mid-Jurassic conglomerates were deposited in a fan-delta to terrestrial setting. Rounded to subrounded volcanic clasts dominate with subordinate volcaniclastic, plutonic (c. 15%), and rare metamorphic clasts.
The 18 plutonic clasts geochemically analysed (whole-rock; ICP) range from quartz monzodiorite to alkali feldspar granite (59–79 SiO2 wt%) and generally have subduction-related arc geochemistries. The majority are I-type but a small number have weak A-type affinities, and one is strongly A-type. Three volcanic clasts were also analysed. Three of the 21 total clasts analysed have adakitic (HiSY) affinity. Subduction-related characteristics are seen such as negative Nb and Ta anomalies. Clasts from all the conglomerate horizons have petrographic similarities.
Zircons from 13 plutonic clasts have been dated by LA-ICP-MS yielding the following 208Pb-corrected concordia ages with 2σ errors. The main clast age cluster is broadly Middle Permian (258 ± 3 Ma, 263 ± 2 Ma, 266 ± 3 Ma, 268 ± 3 Ma, 269 ± 3 Ma, 270 ± 3 Ma, 272 ± 2 Ma). In addition there are clasts with younger Triassic (218 ± 2 Ma, 240 ± 3 Ma) and Jurassic (168 ± 2 Ma, 187 ± 2 Ma), and older latest Carboniferous (300 ± 3 Ma) and mid-Carboniferous (333 ± 3 Ma) ages. An igneous clast with an age that is penecontemporaneous with its depositional age was found in both a Middle Jurassic and Late Triassic conglomerate. It is possible that the False Islet, North Head, and Slope Point conglomerates have the same broad depositional age, and could represent the same stratigraphic level.
Many of the analysed clasts show similarities with units within the adjacent Median Batholith on the basis of their combined petrography, geochemistry and age characteristics. The Darran Suite shows an excellent match with the 168 Ma clast (Rakeahua Pluton and Hunter Intrusives), and the 218 Ma clast with Mistake Suite. The 300 Ma A-type alkali feldspar granite clast is comparable to the Freds Camp Pluton of the Foulwind Suite, and the 333 Ma clast may be from a younger Tobin Suite member such as the Lake Roxburgh Tonalite. The Permian cluster is difficult to correlate with New Zealand rocks. Alternatively, the source of these may extend to the voluminous Mesozoic to Late Palaeozoic batholiths that occur in formerly contiguous eastern Australia and West Antarctica.
This study has shown that conglomerates can be an important tool when investigating the provenance of a sedimentary tectonostratigraphic terrane. Conglomerate clasts provided hand specimen size samples of source rocks to the Murihiku Terrane. This size of sample allowed for much more extensive geochronology, petrography, and geochemistry analysis than could be otherwise carried out on detrital grains within the dominant finer grained sandstone lithologies. Conglomerate clasts therefore provide more robust evidence to any provenance determinations.

Abstract
The Abstract for this thesis
The provenance of sediments in the Western Southland Basins has been investigated using Ti-in-quartz geothermometry in conjunction with cathodoluminescence imaging, petrography and zircon geochronology. Data from the Fiordland basement along with the Te Anau, Waiau, Balleny and Winton basins are reported and used to interpret basin and source correlations, history, and regional tectonic evolution.
Ti-in-quartz analysis yields unimodal peaks for all samples and equilibration temperatures that fall within a relatively restricted range. The data are useful in making empirical comparisons between: basement rocks and sediment, the different basins sampled and sediments within these basins. Differences between samples allows for discrimination between individual samples and basins. Similarities between samples are consistent with previous correlations. The data suggests a shift in Ti-in-quartz temperatures in relation to the stratigraphic sequence. Absolute Ti-in-quartz temperatures of Eastern Fiordland granite and numerous basin samples systematically yield equilibration temperatures below the wet granite solidus. This limits the resolution of the technique.
Detrital zircons from five of the six samples analysed show an almost absolute dominance of Early Cretaceous U-Pb ages. This is consistent with the interpretation of an Eastern Fiordland provenance for these five samples. The Blackmount Formation is strikingly different and appears not derived from Fiordland but from rocks of New Zealand’s Eastern Province.
Subtle features displayed in the Ti-in-quartz geothermometry and zircon geochronology results suggest migration of the sediment sources from the Eocene through to the Miocene. A combination of all information acquired is used to consider basin and regional tectonic evolution.

Abstract
The Abstract for this thesis
Provenance of ancient and Cenozoic East Otago and Canterbury Basin sedimentary rocks, modern Haast River and Wairau River bedload river sediment have been investigated using titanium-in-quartz geothermometry grain size analysis coupled with petrography and detrital zircon geochronology. Titanium-in-quartz geothermometry allows determination of crystallisation temperature of quartz on the basis of measured titanium (Ti) concentrations at known pressure and titanium activity ( ). Calculated using the Ti-in-quartz concentration, temperatures can be precise (often better than ±15˚C) for quartz in igneous and metamorphic rocks. Temperature estimates for hydrothermal veins and detrital grains involve additional uncertainties. Analysis of quartz grains is relatively simple and rapid, with data obtained using LA-ICP-MS. Where loose sediment was sampled, grain size splits of 125 – 250, 250 – 500, and 500 – 1000 μm were analysed. To ascertain the possibility of variation in detrital quartz temperatures between grain sizes in sedimentary rocks. Within sediments inferred to be sourced from metamorphic rocks, higher temperature quartz is observed to occur with the smallest 125 – 250 μm split.
Modern Haast River sediments represent detritus eroded from the Southern Alps through pumpellyite-actinolite greenschist to garnet-oligoclase amphibolite facies metamorphic basement rocks of the Alpine Schist. Detrital quartz temperatures were observed to vary between grain sizes analysed, with higher temperature quartz typically found within the 125 – 250 μm split. Comparatively the catchment of the Wairau River is composed dominantly of Torlesse Supergroup Greywacke and chlorite greenschist facies Marlborough Schist. A dominantly bimodal distribution was observed throughout all grain sizes analysed with no grain size partitioning of temperatures. Ancient sedimentary lithologies of the East Otago sedimentary sequence and Canterbury Basin reflect widespread marine transgression associated with separation and submersion of the New Zealand continent from Gondwana during the late Cretaceous to late Oligocene. Alpine Fault inception occurred during the Miocene and correlates with deposition of marine regression sedimentary sequences. Additional zircon geochronology was applied to the Green Island Sand to confirm Ti-in-quartz results and provenance interpretations.
Ti-in-quartz geothermometry and zircon geochronology provenance interpretations have been found to agree with previous work on ancient sedimentary lithologies and inferred provenance of modern river sediments. Sediments analysed were able to be effectively correlated to basement rocks from around the New Zealand continent. Ti-in-quartz geothermometry has been found to enable provenance determinations from quartz-rich sediments which are geologically reasonable and in keeping with interpretations from studies using other provenance methods.

Abstract
The Abstract for this thesis
The New Zealand micro-continent has been described as an amalgamation of various tectonostratigraphic terranes which were accreted on to the Gondwana margin. The origin of the accreted terranes is important in the understanding of Phanerozic Pacific tectonics. This study aims to help in the understanding of the provenance of the Torlesse terrane, which has been subject to extensive geological research for decades. A conglomerate horizo11; located on the southeast side of Lake Hawea was examined with the aim of using the conglomerate clasts to provide provenance information on the Torlesse terrane, in particular the Rakaia terrane. Conglomerate clasts are coarsegrained hand specimen size samples of the source rock, which have thought to have travelled a shorter distance than the fine-grained detrital material which make up the Otago Schist and therefore are able to be used to trace proximal sources. The size of the clasts also allowed for much more extensive geochronological, geochemical, petrographical and geothermometry analysis than that of the fine-grained lithologies within the schist and therefore provide a more confident indicator of provenance. An additional goal of the studywas to understand the effect of metamorphism and deformation on the clasts. Based on geochemical and mineralogical observations, the majority of the clasts can be classified as fractionated I-type tonalite. Petrographic observations show that the clasts have been subject to low grade metamorphism, with the presence of recrystallised quartz and microfractured feldspar, pressure shadows and growth of stilpnomelane. Petrographic and geochemical observations indicate that the clasts have been subject to metasomatic additions ofNa20, Si02 and C02 and the removal ofK20, Rb and Ba during progressive metamorphism and deformation. Titanium (Ti) concentration in quartz grains for the three localities was determined by LA-ICP-MS. These data were combined with the revised calibration of Thomas et al. (2010) to estimate crystallization temperatures. Results show that at low metamorphic grades the original igneous Ti-in-quartz temperature was preserved, but with increasing metamorphic grade and textural zone the temperatures re-equilibrate. 111 U-Pb zircon ages for the five selected clasts and a schist sample were determined by LA-ICP-MS. Four igneous clasts yield crystallisation ages, 253±3 Ma, 298±3 Ma, 332±7 Ma and 339±6 Ma. A quartzite sample has detrital zircons that range in age from 440 to 2650 Ma. Detrital zircons within a schist sample showed a prominent Permian to Triassic age peak and correlate well with the ages of the clasts. The crystallisation ages of the clasts and the detrital ages of the schist and quartzite broadly correlate best with crystallisation ages of igneous complexes located within Western Antarctica.

Abstract
The Abstract for this thesis
The nature and provenance of the Jurassic McPhee Cove Conglomerate, Murihiku Terrane, New Zealand, has been investigated using clast petrography, geochemistry and age. The McPhee Cove Conglomerate forms three strike belts within a 12 sqkm area in the Catlins, southeast Otago. The outcrop studied here is based mainly on 50m high cliffs immediately south-west of Tautuku Peninsula at l.athyrus Bay. The McPhee Cove Conglomerate is a 50m thick, polymict, mostly metre bedded, unfossiliferous, poorly sorted orthoconglomerate, with minor sandstone interbeds. Clasts are rounded to well rounded and range in size from granule to boulder. The conglomerate is Ururoan to LowerTemaikan in age and is underlain by the Otekura Formation and overlain by the Purakauiti Formation. It is intetpreted as debris flow deposits, deposited on a shallow submarine-fan. The McPhee Cove Conglomerate consists of plutonic (31% ), volcanic (33% ), volcaniclastic (sedimentary) (34%) and lesser metamorphic (2%) clasts. The plutonic clasts have island arc geochemical characteristics, are calc-alkaline in composition, have 1-type plutonic characteristics and range from granite, granodiorite to monzodiorite, but are dominated by high Si02 (70-76 wt%) granites. The volcanic, volcaniclastic and metamorphic clasts also have island arc geochemical characteristics. Volcanic clasts range from rhyolite to basalt and the volcaniclastic dasts are weakly metamorphosed, dominantly crystal-lithic volcanic sandstones to breccias. The metamorphic clasts are quartzofeldspathic gneisses. Geochemical analyses have defined two clast populations. The majority of the plutonic (81% ), volcanic, volcaniclastic and metamorphic clasts have similar geochemical compositions and representative samples from this group have yielded Permian U-Pb dates of 260±5 Ma and 268±5 Ma This suggests that this group as whole may have been derived from a dissected Permian arc. A secondary population, although similar petrographically to the group discussed above, has geochemical characteristics that deviate from the main population. This smaller group is composed of alkali feldspar granites, samples with adakitic geochemical affinities, and monzonites to monzodiorites. Samples from this group have yielded Jurassic dates of 186±6 Ma and 181±6 Ma. Assuming that the dated samples adequately represent the two populations then at least two suites of arc rocks have supplied detritus to the McPhee Cove Conglomerate. Although the clasts show a broad resemblance to igneous rocks of the Median Tectonic Zone, on the combined basis of petrography, geochemistry and geochronology no source terranes for either the Permian or Jurassic groups are presently recognised in New Zealand.

Abstract
The Abstract for this thesis
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 Let ham Ridge Thrust. The rocks to the west of the thrust comprise the steeply-dipping, eastward-younging, volcanoclastic sediments of the Takitimu Group. Pyroxene-phyric basalt and two-pyroxene andesite dykes intrude the Takitimu Group. A diorite plug with associated marginal sulphide mineralisation, and the Early Triassic hornblende andesite sills of the MacKinnon Peak lntrusives, intrude the Takitimu Group. An olivine monzonite dyke outcrops within the Takitimu Group to the north of Wether Hill, it is post Early Triassic in age. The Takitimu Group is unconformably overlain by gently eastward-dipping Jurassic sediment of the Barretts Formation. The Barretts Formation is comprised of conglomerate, sandstone, and siltstone, containing volcanic, plutonic, and metamorphic detritus.
The Speights Limestone Melange outcrops within the Letham Ridge Thrust. Blocks within the melange include Permian limestones, sandstones, and siltstones.
The Murihiku Supergroup is thrust over the Barretts Formation along the Letham Ridge Thrust. The Murihiku Supergroup within the area is comprised of Early to Late Triassic volcanogenic sediment, and two-pyroxene andesite. The sediments record a change from predominantly andesitic detritus in the Early to Mid Triassic to more felsic detritus in the Late Triassic.
Petrographic data from sandstones of the Barretts Formation indicates that the sandstone composition is heterogeneous throughout the unit. The sandstone composition varies from lithic-rich {e.g Q:F:L-7:33:60) to quartzofeldspathic {37:34:29). The variable nature was also noted in the geochemical composition of the sandstones. Immobile trace element and major element concentrations vary between samples. Geochemical and petrographic work confirmed that the Barretts Formation was derived from a continental arc margin. Petrographic and geochemical differences suggests that the Barretts Formation and the Murihiku Supergroup did not share the same source during the Jurassic.
The Late Cretaceous New Brighton Conglomerate overlaps both terranes. Sediment within the New Brighton Conglomerate has a higher proportion of intermediate to mafic volcanic, and sedimentary lithics, than sediment from the Barretts Formation, suggesting significant differences between these units.
Small areas of Eocene coal measures of the Nightcaps Group unconformably overlie the Takitimu and Murihiku basement within the field area.

Abstract
The Abstract for this thesis
A structurally complex Cenozoic sequence overlies two basement terranes in the Princhester Creek area. Basement rocks comprise Permian Takitimu Group and Triassic Murihiku Supergroup. They are juxtaposed by a major N-S striking fault. The basal Cenozoic sediments are 450 metre thick Eocene coal measures of the Nightcaps Group (Beaumont Formation). A low angle unconformity separates the Beaumont Formation and the Murihiku basement on the NW flanks of Mount Hamilton. Elsewhere there are faulted contacts against basement rocks. Overlying the non-marine unit is a thick sequence of Oligocene marine basin sediments of the Waiau Group. Spear Peak Formation (900 metres thick) is in sedimentary contact with the Beaumont Formation. It is overlain by thick mudstone (possibly over 1000 metres) of the Waicoe Formation. Faulted against both these formations is the Weydon Formation of unknown thickness and similar Whaingaroan age. Younger pre-Quaternary sediments do not appear in the Princhester area.
Sediments record that the Takitimu block underwent rapid uplift early in the Whaingaroan and that the Fiordland block remained uplifted throughout the Eocene and Oligocene. From the Miocene to the present, right-lateral transpression (associated with strain on the Indian-Pacific plate boundary) has been partly concentrated along the Moonlight Fault system and partly distributed throughout the basement. The resultant rotation, shortening and uplift of basement blocks in the Princhester area is shown by basement structures and reflected in the highly deformed Cenozoic cover.

Abstract
The Abstract for this thesis
An area approximately 36 km2, located 26 km southeast of Te Anau, Western Southland was mapped in detail. In the south, Permian rocks of the Takitimu Group (northern Takitimu Mountains), comprise a variety of volcanoclastic sediments including tuffs, volcanic breccias, sandstones and andesites. In faulted contact with the Takitimu basement, to the north, are Cenozoic sediments of the Te Anau basin. In stratigraphic order, these sediments begin with the non-marine Beaumont Formation of Eocene age ( 430 metres thick) passing up into marine sediments of the Oligocene Spear Peak Formation (1080 metres), Elm Tree Limestone (55 metres) and the Waicoe (Mudstone) Formation (1600 metres) both early Miocene. Unconformably overlying the Waicoe Formation are late Miocene fluvial deposits of the Prospect Formation. Quaternary deposits record three periods of glacial advance, from oldest to youngest these are, Whitestone Stratified Drift, Elmwood Formation and the Mavora Outwash Member.
Petrographic, QFL data and major element analysis of biotite rich quartzofeldspathic sandstones from the Beaumont Formation indicate derivation from a plutonic source , that was part of a rapidly eroding Eocene tectonically active margin in what is now Eastern Fiordland.
Lithological and stratigraphic differences have permitted subdivision of the Spear Peak Formation into two members; Elmwood-Waituna member ( 500 metres) and the Wood Hill member (1080 metres). The Spear Peak Formation indicates the onset of marine conditions in the late Eocene and early Oligocene and the establishment of rapidly subsiding basins associated with movement on the Moonlight Fault System. Olistoliths of Takitimu Group rocks are found within both members, but Fiordland derived material sediment remains present as well. A limestone breccia in the Wood Hill member contains limestone clasts showing mylonitic deformation features. Recrystallised Atomodesma prisms within the clasts closely resemble similar prisms in the Melita limestone in the upper Eglinton Valley.
The Waicoe Formation, a deep marine mudstone of widely varying age found throughout the Te Anau and Waiau basins, is shown to be Altonian age in Elm Tree Creek (benthic and planktic foraminifera). Mass flow deposits within the mudstone indicate reworking of shallow marine shelly sediment into deeper waters.
Prominent northeast-southwest trending faults passing through the area mapped, such as the Takitimo Fault and older, less continuous, northwest- southeast trending faults are a continuation of the Moonlight Fault System. Recent Fault tracing indicates that deformation remains active into the Holocene.

Abstract
The Abstract for this thesis
Eocene - Oligocene sediments in the Lake Hauroko area, Western Southland, occur in three fault-bounded basins known as the Monowai Sub-basin, the Waiau Basin, and the Fiordland Shelf Basin. The Hauroko Fault (southern segment) trends north-east across the lower reaches of Lake Hauroko and splays into three faults; the Hauroko Fault (northern segment), the Blackmount Fault, and the Oblong Hill Fault near Steves Point. The Monowai Sub-basin lies between the two former faults and is bisected by the latter. The two halves are referred to as the West Monowai Sub-basin and the East Monowai Sub-basin.
Four regional formations are recognized: (1) the Blackmount Formation (conglomerate and sandstones), (2) the Tunnel Burn Formation (limestone), (3) the Lill Burn Formation (calcareous sandstone), and (4) the Waicoe Formation (mudstone), which are internally subdivided into lithogenetic members according to the basin of deposition. The Blackmount Formation is subdivided into: (i) the Kaherekoau Member, (ii) the Hump Ridge Member, and (iii) the Caroline Member. The Tunnel Burn Fom1ation is subdivided into: (i) the Hill Member, (ii) the South Arm Member, and (iii) the East Arm Member. The Lill Bum Formation is subdivided into: (i) the Eel Member, and (ii) the Oblong Hill Member. The Waicoe Formation is everywhere uniform in lithology.
The stratigraphic order of litho-units in the West Monowai Sub-basin begins with the Kaherekoau Member, overlain by the Waicoe Formation. The Hill Member, occurs as a fault-bounded sliver within the Waicoe Formation. In the Eastern Monowai Sub-basin, the oldest stratigraphic litho-unit is the South Arm Member, overlain by the Lill Burn Formation and then the Waicoe Formation. The stratigraphic order of-the Waiau Basin begins with the Hump Ridge Member at the base, stratigraphically overlain by the East Arm Member. The Caroline Member is the basal litho-unit of the Fiordland Shelf Basin.
The Eocene- Oligocene sediments in the Lake Hauroko area are interpreted as having been derived from immediately adjacent Fiordland basement. West Monowai Sub-basin litho-units are derived from mixed source terrain of probable Eastern Fiordland provenance and granitoids of uncertain affinity (Southwest Fiordland?). East Monowai Sub-basin sediments are derived from a mixed source terrain of granitoids of uncertain affinity (Southwest Fiordland?) and Eastern Fiordland basement lithologies. Waiau Basin sediment is derived from basement lithologies in the Green Lake region at Tangney Bend, Lake Monowai. A point source has been positively identified for detrital aegerine and arfvedsonite as being the Monowai gneissic granite. Fiordland Shelf Basin sediments are derived from a mixed source tenain of granitoids of uncettain affinities (Southwest Fiordland?) and possible Western Fiordland.
A minimum of 18 kms of dextral strike-slip has occuned on the Blackmount Fault - Hauroko Fault (southern segment) part of the Moonlight Fault System. Approximately 3 - 5 kms of dextral strike-slip has occuned on the Oblong Hill Fault and Hauroko Fault (northern segment). Between 0.76 and 1 km of strike-separartion is inferred to have occurred on each of three north-north-west striking faults in the Hump Ridge region, obliquely intersecting the Blackmount Fault - Hauroko Fault (southern segment). Reconstruction of the original geographic positions of the Monowai Sub-basin, the Waiau Basin, and the Fiordland Shelf Basin indicates that the southeasterly extension of the Grebe Fault Zone may be the Hump Ridge Fault, a major fault separating the Waitutu Basin to the southwest from the Monowai Basin the the north east. Folding is interpreted as pre-dextral strike-slip.
