They affect the road and rail networks that are a major lifeline to the city ofDunedin. State Highway 1 runs through this area and was realigned in the late 1960s. This led to slope stability issues such as the Site Office Slide. The underlying geology of the area is dominantly made up of the clay rich Onekakara Group, with knobs ofvolcanics and sandstones resting on top. The abundance of Onekakara Group located at the surface is the main reason behind slope stability issues found in this area. Analysis revealed that slope failures dominantly occur in the southeast direction, and less so in the northwest direction. Low angle slopes were shown to offer little resistance to slope failures, with the majority of failures occurring between 1 0 - 20 degrees. Mass wasting is occurring on a large scale with 3 - 4 large landslide complexes, slowly creeping towards the coast. Within the debris of these complexes slope failures are common and generally occur as debris flows. A simple landslide hazard map was produced and indicated regions of high, medium and low risk. It was found that the majority of SH 1 lies within the high-risk category. Residential areas at Warrington and baches along the coast lay within the low risk category. This may have implications for future development in the area, but it is suggested that the hazard map be used as a qualitative guide to susceptibility to slope failures.

Abstract The Abstract for this thesis A suite of alkaline rocks, geochemically similar to those of the Dunedin Volcano are described and implications arising from their study are discussed. Rock types studied include basanites, basalts, hawaiites, benmoreites and trachyandesites. A summary of Benson's work on Landslide features in the Seacliff district is also included, with present day observations. Major and trace element whole rock analyses are presented. Three possible geochemical trends are suggested: Two sodic series : (a) basalt-hawaiite-(mugearite)-trachyandesite-benmoreite. (b) basanite-nepheline hawaiite-(nepheline mugearite)-nepheline benmoreite. A more potassic undersaturated series (c) basanite-nepheline hawaiite-nepheline trachyandesite-nepheline benmoreite. An electron microprobe study of the mineralogy of a trachyandesite from the pyroclastic breccia unit at Green Point, which contains an unnamed mineral, has been done. A detailed study of the Green Point to Brinns Point coastal section has been carried out and a possible eruption mechanism proposed. The rocks from the Seacliff area are geochemically similar to the more potassian members of the Dunedin Volcanic Complex. Department The department where the student is studying primarily.
