Abstract The Abstract for this thesis Between Pahia Peninsula and Kawakaputa Bay to the East, a S.E. trending arm of crystalline rock separates Foveaux Strait from a strip of fossil estuarine clays and sands. To the East, Oraka Peninsula performs the same function. The two topographic features are the result of adamolite and granodiorite masses respectively intruding a previously emplaced gabbroic mass composed mostly of norite. The following phenomena are thought to have occurred. The formation of an auroole (probably no more than 200' thick) at the contact between the norite and the intruding acid body. Hybrid rocks are formed due to the metasomatic hydrothermal effect on the norite of emanations from the acid body. Mechanical mixing in places causes a very distinctive microscopic lithology which is, however, difficult to distinguish from in hand specimen, those rocks that have undergone 'in-situ' metasomatism. The contamination of the acid magma by reciprocal reaction between the magma, and the myriad basic inclusions within the magma, that are thought to have been derived from the noritic wall rock. The acid rocks(at Wakapatu at least) are believed to have been basified from an original adamellite gradationally through to a diorite. (these are so named on the basis of(Or/0r+Ab), because it is thought that orthoclase, in this case, is a most important mineral. Its concentration is indicative of.tho processes at work) The presence of a large regional batholith (probably equivalent to Anglem Complex rocks), intruding norites(Bluff Complex probably) for the whole Longwood-Wakapatu-Pahia-Bluff-Stewart Island-Ruapuke Island region North of the Median Tectonic Line, and possibly extending much further North than the Longwoods,is postulated.

Abstract The Abstract for this thesis A layered gabbro overlying granodiorite and a sequence of hornblende-bearing and quartzofeldspathic gneisses have been described from an area of 25km2 about Lake Hankinson and the N.W. Arm, Middle Fiord, Lake Te Anau. The gneissose rocks represent a westward younging sequence of basic and semibasic (basic-intermediate) lavas and tuffs overlain by quartzofeldspathic and possibly calcareous sediments. This sequence has been completely recrystallised by amphibolite grade metamorphism. South of a roughly E-W trending line through the centre of the area (the Howitt Peaks Fault) gneissose rocks are uncommon. Instead, a flat-lying sequence of differentiated ultrabasic rocks, approximately 550 feet thick, overlie felsic igneous rocks of a dominantly granodioritic composition. This sequence is in various stages of recrystallisation under the influence of amphibolite grade metamorphism~ The degree of recrystallisation is largely dependent on the composition of the original rock. Study of a range of secondary phases by optical and X-ray methods, suggest that mineral composition is also largely dependent on the composition of the original rock. Two phases of faulting accompanied by retrogressive metamorphism and crush zones disrupt all lithologies and give rise to intermixing of adjacent rock types. On the basis of tectonic position and associated rock types the N.W. Arm gabbro is thought to be genetically related to the Mt Luxmore Ultrabasics of the South Fiord, Lake Te Anau. Comparisons with Central Fiordland gabbroic bodies are also considered. Department The department where the student is studying primarily.

Abstract The Abstract for this thesis Fiordland gneiss, epidiorite and granodiorite are mapped and described together with an onlapping transgressive sequence of Cainozoic sediments. Amphibolite, plagioclase-biotite-hornblende gneiss and plagioclase-biotite. gneiss are differentiated within the gneisses previously mapped by Wood (1962) as Wet Jacket Formation. A basic intrusion, the Garden Point Epidiorite, occurs in the southern part of the study area, and is considered an offshoot of the main Mt. Luxmore basic and ultrabasic intrusive body. The synmetamorphic Takahe Granodiorite (new name) occupies the greatest area in the region studied and is considered similar to other Eastern Fiordland acid intrusives. Whole rock geochemical analysis was undertaken on the gneiss, epidiorite and granodiorite. The results obtained were used in correlation with other Eastern Fiordland rocks as well as providing information on depth and temperature of emplacement (granodiorite), primary lithology (gneisses) and cryptic variation (epidiorite). The onlapping Cainozoic sediments are studied, and type sections proposed for the formations originally named by McKellar (1956). Thirteen lithofacies (A - M) are recognized within the sequence. Palaeontological, petrographic and sedimentologic evidence is used to infer a depositional history and palaeogeography, The sediments, non and shallow marine sandstones and limestones overlain disconformably by a condensed sequence, hemipelagic muds, redeposited sands and flysch are strongly influenced by the interpreted tectonic history of the Moonlight Tectonic Zone.
