Abstract The Abstract for this thesis Up-to-date geochemical information about New Zealand scheelite is lacking; the last recorded analyses were published in 1945. New methods of analysis such as Atomic Absorption are now available and 14 new analyses are presented, the results of which can be used to correlate between the scheelite fields but only to a limited extent. Atomic Absorption has been used to determine tungsten, the results of which have been checked gravimetrically. Molecular absorption is reported by sodium carbonate. Large variations in the iron and magnesium results indicate absorption of the sediments by platinum. Interference is reported in the colourimetric determination of silica. A petrographic investigation suggests that early-formed quartz and scheelite have crystallised more or less simultaneously and were followed by calcite. Fracturing and cataclasis have introduced new solutions which have partially replaced the early formed minerals. Department The department where the student is studying primarily.

Abstract The Abstract for this thesis A Lower Permian geosynclinal sequence, previously mapped as Eglinton Volcanics, is found to be predominantly volcanogenic feldspathic sandstone and siltstone with minor tuffs, tuffaceous sandstones, Atomodesma bearing limestone and keratophyres. The sequence is divided into the Falls Creek Formation, (which includes the Melita Limestone Member), Kaka Creek Siltstone, Consolation Formation, Divide Creek Formation and Fergus Formation - all newly defined. Correlation with other areas is discussed. The rocks have been metamorphosed to prehnite-pumpellyite and pumpellyite-actinolite-schist facies. Justification for the use of the name Alabaster Group, rather than Eglinton Volcanics, is given. Basic and ultrabasic dykes, intruding the above sequence, are described in some detail. A quartz-dolerite intrusive body, here named the Gunn Intrusives, is tentatively correlated with the Mackay Intrusives. To the west, in fault contact (Skelmorlie Fault) with the Alabaster Group, is the so-called Darran Diorite. In this urea it is actually oligoclase-granite and hence it is proposed that the name Darran Complex be used. Rafts in the Darran Complex are metamorphosed to hornblende-hornfels facies. Graben fault blocks of Otamitan and Tertiary marine sediments are infaulted along the Hollyford Fault, which bounds the eastern edge of the Alabaster Group. The sparsely fossiliferous Otamitan (Windy Point Formation) is comprised of sandstones, siltstones, tuffs and conglomerates and is correlated with the Murihiku Super-group. Analcime from one tuff-bed has a composition identical to that of analcim from burial metamorphic rocks of the Taringaturas, Southland. Metamorphism is to zeolite facies. The sparsely fossiliferous Lake Lochie Beds (L-P age) consist primarily of arkosic sandstones (derived from Fiordland Complex) with rare volcanic conglomerates (derived from the Eglinton Volcanics.

Abstract The Abstract for this thesis A map and description of the geology of 9 square miles of the Romahapa area is presented. The area is underlain by sedimentary rocks of ?upper Palaeozoic and lower Mesozoic age. Fossil evidence fixes the age limits as Permian or post-Permian to pre-Oretian. The oldest rocks of the area are described as two new formations, a lower North Romahapa Conglomerate and an upper Waituti Formation, comprising the North Romahapa Group. A distinctive conglomerate from this group is described in lithologic and petrographic detail. The group is established on lithologic grounds. The other rocks of the area are not so extensively described. Where applicable all rocks are described and compared using Folk's sandstone classification. The vast majority of the rocks fall in the "volcanic arenite" area of this classification. Alteration effects are considered to be consistent with zeolite facies metamorphism. A tentative structural interpretation is given, based on the limited field data available. It is not claimed to be the only possible interpretation, nor necessarily the correct one, and is likely to be a gross simplification. On its basis, an episode of deformation of possible late Permian age is tentatively suggested. Finally a brief section on economic geology is presented.

Abstract The Abstract for this thesis Approximately 17,200 ft. of Permian strata, exposed on the south-east margin of the Takitimu Mountains Southland, New Zealand, are chiefly andesitic and basaltic lavas and diorite silts, as well as clastic and sedimentary rocks whose constituent particles were derived from Permian pyroclastic eruptions of augite (and hornblende) andesites. These rocks were steeply tilted and eroded before the deposition of Triassic volcanogenic sediments which now rest unconformably on the Permian strata. During diagenesis volcanic glass has crystallized to heulandite and analcime, and associated minerals are chlorite, celadonite and prehnite. Plagioclase has altered to albite and one or more hydrous Ca-bearing minerals, including prehnite. Albitization is incomplete on every scale. Laumontite is only found in veins, and stilbite is common in cavities of volcanic rook. Gravimetric determination of the amount of silica in two of the Permian basalts gave values of 48.87 and 48.16%.Average K2O, Na2O and K2O:Na2O values for Permian Volcanics are respectively 1.091 3.23 and 0.29, which coincide with volcanic belt No.1 of Challis (1968). The discovery of Mellarium in a partly calcified conglomerate establishes the presence of a new Etalian locality near Wilanda Downs. A new Formation in the Productus Creek Group (Mt. Wilanda Limestone) is defined. Department The department where the student is studying primarily. Geology Named locality Named locality describing the field area location.

The Haast schists consisted of massive and layered rock; the major mappable schist structure was a planar schistosity, and minor locally developed mesoscopic folding was observed. The Stranraer Group was subdivided into the Horse Burn and Hyde Formations, and the Hyde Formation was subdivided into the Fullarton and White Cliffs Members. Marine, glauconitic, sparsely fossiliferous, Bortonian (mid Eocene) age Horse Burn sands were deposited as a thin prism only in the north-east corner of the mapped area. During fresh-water Fullarton deposition gravels and sands poured into two localised, structurally controlled depocentres, and a thin sheet of Fullarton sediment was deposited across part of the remainder of the area. Fullarton sediments overlay Horse Burn sands in the Horse Burn type section. The White Cliffs depositional event was in part marine, at times hypersaline. White Cliffs sediments overlay Fullarton sediments in the west and south, and lay directly on schist in the centre of the examined area. A thin flow of Waipiata basalt overlay the Stranraer Group, and formed resistent caps on flat-topped hills near Hyde, and the extrusive centre, a large and structurally differentiated lava pond intruded by a sub-parallel dike swarm and numerous plugs, was exposed near Tiroiti. Correlation of Stranraer rocks with sections to the south and north-east indicated that in the Tertiary the Hyde area was situated near the shallow southern edge of a transgressive sea that passed inland to the north and west, and back to the present day coast, with only minor influence on the local depositional history.

Fieldwork was carried out during early 1969, sixteen days being spent in the field. Access is by logging road from Papatotara , or along the beach, which is safe for cars at low tide. Dense scrubby bush obscures outcrop except for portions of the coastal cliffs and the mouths of streams. Rowallan Burn, Birch's Mill and Waikoau River are the only formally named localities, all other names have been coined by the author to aid description of specific localities. The author wishes to thank the Benson Memorial fund for assistance with field expenses; Dr. R.M. Carter, Associate Professor J. D. Campbell and Mr. C.A. Landis for much helpful advice; the author's parents and relatives, Miss B. More, Miss A. Guilford, and Mcintyre's Milling Company for assistance in many ways.

Conference, November 29th, 1969) Schist Structure and Stratigraphy, Faulting and Tertiary Sedimentation in the Queenstown-Bob's Cove Area I.M. Turnbull University of Otago The schist in the Bob's Cove-Queenstown area grades from Chl II to Chl lV and is dividible into 3 stratigraphic units, one of which extends 30 miles to the north, Younging directions and mesoscopic folds in bedding and bedding foliation (termed F1 -folds) show that these units are on the overturned limb of a nappe-like fold with an axis plunging 45° SW and rooting to the NW. Another generation of folds in foliation (F3- folds) is developed close to major faults and individual folds can reach macroscopic proportions, F3 folds were developed during a period or sub-horizontal east-west compression which initiated movement on the Moonlight Fault and other major faults in the area. A new occurrence of marine Tertiary strata (?Landon) is mapped along the downthrown side of a newly-discovered major reverse fault (the 2 Mile Creek Fault) 5 miles E of, and parallel to, the Moonlight Fault. Another NNE-striking fault passes through the summit of Wedge Peak and a third parallels the S bank of 12 Mile Creek to be truncated by the Moonlight Fault. Landon rocks at Bob's Cove are bonded by the Moonlight Fault on the west and rest unconformably on sohist to the east. Lithological evidence shows that those sediments and those in the 2 Mile Creek and Moonlight Fault zones were derived from schist up thrown to the west during a second phase of movement on the Moonlight Fault. A marine connection of the Te Anau Basin is also postulated in some places, as at Bob's Cove, the sediments have been folded in F3 style by the latest period of fault movement in the area.

Abstract The Abstract for this thesis The area round Cascade Creek from the Livingstone Fault to the Te Anau - Milford road has been mapped. Previous work on the Permian sequence in Otago - Southland and Nelson is examined in some detail. Group names applied to the rock formations of the area are; Humboldt, Brook Street and Maitai. Reasons for this nomenclature are given in Appendix 1. A section of the Eglinton Volcanics along Cascade Creek is described, lithologies present include quartz keratophyre, andesite and volcanogenic sediments. An infaulted sliver of Murihiku Supergroup may be represented by one outcrop in the creek. The north end of the southern section of the Livingstone Volcanics occurs one mile south of Cascade Creek. These rocks are briefly described and classified as epidiorites. The Red Mountain Ultramafics consist of sheared serpentinite, blocky serpentinite and tectonic inclusions. X-ray analysis of the sheared serpentinite suggests that all three serpentine polymorphs are present, viz., antigorite, crysotile and lizardite. Two types of tectonic inclusions are recognised, those with dioritic composition, and those metasomatised to rodingite. X-ray analysis of hydrogrossular from five rodingites suggests a low degree of hydration and a formation temperature (630 - 750°C) outside the stability field of serpentine - assumed to be 500°C. Chlorite from inclusion margins is moderately aluminous and rich in magnesium relative to iron. It is not known whether the ultramafics were laid down before the Livingstone Volcanics or subsequently intruded along the Livingstone Fault. The steeply dipping sediments exposed between the Eglinton and Livingstone Volcanics are referred to as the Maitai Group. Volcanic breccias, sandstones and argillites underlying the Howden Limestone, and previously included in the Livingstone Volcanics, are placed in the newly defined Cascade Formation. The type section is situated half a mile south of the triple forks in Cascade Creek. Atomodesma - bearing Annear Sandstone overlies the Howden Limestone and is overlain by the massive, unfossiliferous, well sorted Key Summit Sandstone. Most of the Maitai sediment is volcanically derived. Alkali analyses of the two volcanic suites show a higher K20:Na20 ratio in the Eglinton Volcanics. These results are considered to support Challis' theory that the two belts were genetically distinct. The Key Summit Syncline axis is mapped as a faulted axis along the contact separating the Annear and Key Summit Formations The Livingstone and Hollyford Faults are steeply dipping features approximately one mile apart east of Lake Gunn. The strike directions of two other near vertical faults make an angle of approximately 30° with the Livingstone Fault. They may be part of a conjugate set between the Livingstone and Hollyford faults. Active, or very recent scarps near the top of, and parallel to ridge crests, may be the result of gravitational adjustment in mountains whose slopes have been oversteepened by ice movement. All rocks in the area have undergone regional metamorphism. The Maitai sediments contain lawsonite without prehnite and are classified as lawsonite- albite facies. The Eglinton Volcanics are assigned to the prehnite - pumpellyite facies, and the Livingstone Volcanics to the higher grade pumpellyite-actinolite schist facies. A brief geological history is given. The width of Maitai sediments exposed in Cascade Creek is probably the narrowest anywhere along the marginal syncline, and this area may have the greatest depth of erosion in the syncline.

Abstract The Abstract for this thesis A general discussion of the geology of the North Lumsden area, Southland, describes a thick sequence of argillittes, tuffaceous greywackes, and Atomodesma-bearing sandstones of probable upper Permian age, with intercalated and intrusive spilitic and keratophyric volcanic rocks, herein assigned as to the Livingstone volcanic group. A minor amount of an intrusive sodic granite is compared with the Otama complex rocks. I have included a discussion of the possibilities, from the present study, of correlating the Permian rocks from the extremities of the Southland syncline, with no firm conclusions being reached. The petrogenetic aspects of the volcanic rocks are considered, with a conclusion that their present appearance is due mainly to those burial metamorphic effects which affected the enclosing sediments. The compositions of some epidotes have been studied relative to the mode of occurrence of that mineral in the volcanic rocks, and a discussion of various determinative methods is included. An attempt has been made to see if there is any systematic relationship between chemical composition and powder x-ray parameters for samples of the pumpellyite mineral series.
