<p> Forty-Three cores were collected from the region of the Killarney Igneous Complex, southeast of the town Killarney. These cores were analysed by measuring geophysical properties such as bulk susceptibility, percent anisotropy, magnetic foliation and lineation and remanence. The magnetic fabric measured indicated a regional fabric. In some areas the fabric was completely overprinted due to localised deformation. Measured remanence may make it possible to determine the effect of previous deformations; however, none was seen in this study. </p> <p> The petrological fabric was also investigated by taking thin sections perpendicular to the long axis of the core. Again it was possible to see a regional and localized deformation pattern due to reduced grain size, grain alignment and recrystallization. </p> <p> Measurements collected from the samples determined that both the magnetic fabric and petrological fabric showed indications of being near areas of greater deformational intensities. A relationship was then established between the magnetic fabric and petrological fabric on a fine scale. This relationship may aid in determining direction and extent of deformation in the rock bodies when it is not easily identifiable in the field. </p> / Thesis / Bachelor of Science (BSc)

The Neolithic and late Iron Age pottery from the settlement site of Pool, Sanday, Orkney, was studied on two levels. Firstly, a morphological and technological study was carried out to establish a sequence for the site. Secondly an assessment was made of the usefulness of X-ray Fluorescence Analysis, Inductively Coupled Plasma Spectrometry and Petrological analysis to coarse ware studies, using the Pool assemblage as a case study. Recording of technological and typological attributes allowed three phases of Neolithic pottery to be identified. The earliest phase included sherds of Unstan Ware. This phase was followed by an assemblage characterised by pottery with incised decoration, which was stratified below a traditional Grooved Ware assemblage. The change in pottery styles and manufacturing methods with the Grooved Ware indicated that it evolved elsewhere. Grass tempered and burnished pottery characterised the Iron Age assemblage. Pottery samples from all phases of the site were analysed by XRF and ICPS. In addition, pottery from late Iron Age sites in the area was analysed for comparison with the Pool Iron Age pottery. XRF and ICPS analyses did not distinguish between either different phases at Pool or different Orcadian sites. This was attributed to the similarities in geological deposits over much of Orkney and the variations which can occur within a clay source. A clay survey was carried out in the vicinity of the site, and samples taken for comparison with the Pool pottery. Identification of rocks and minerals in thin section, and grain-size analysis, indicated that the Pool pottery was made locally to the site, and that both primary and secondary clays were used. It was concluded that petrological analysis is more suitable than elemental analysis in the study of coarse wares.

<p> A petrological and geochemical study has been carried out on some Archean mafic and felsic volcans of Dome Township, Central Red Lake area, Ontario. Included are a discussion on petrographic descriptions along with chemical investigations of the rocks and a discussion concerning the general problem of petrogenesis. Analytical methods used are explained, and di scussions of the results are included. </p> / Thesis / Bachelor of Arts (BA)
