Micro-geochemistry of the mantle and its volcanic rocks
… comprises three studies which utilise detailed micro-sampling techniques to understand the effects of melt infiltration in the continental lithosphere and the relationship of deeply derived kimberlite melts to lithospheric processes. To be able to make these links it is necessary to better …

Development of techniques for high-resolution spatially-resolved elemental analysis in materials of interest in luminescence dating
… likely concentrations of uranium and thorium. Micro-sampling techniques were developed to produce material for instrumental analysis (ICP-MS and AAS), to provide quantitative information about the concentrations of uranium, thorium and potassium in the areas of interest, highlighted by the …

Of His Bones are Coral Made: Submerged Cultural Resources, Site Formation Processes, and Multiple Scales of Interpretation in Coastal Ghana
… processes across a range of scales from micro-artifact to region and from historical to environmental processes, this work explores the archaeology of the event related to submerged archaeological sites within the Elmina seascape of coastal Ghana. Building on and intersecting with the …

Pollution of soils by lead and its uptake and pathways in the ecosystem.
… intralaboratory precision. A stratified random sampling protocol was developed and evaluated which allowed an estimate of precision to be placed on the results of the trace metal soil survey. An assessment was carried out of the contribution that lead fromaerially deposited dust and soil sources …

Analytical method development for structural studies of pharmaceutical and related materials in solution and solid state. An investigation of the solid forms and mechanisms of formation of cocrystal systems using vibrational spectroscopic and X-ray diffraction techniques
… these studies the high selectivity and direct micro sampling of Raman spectroscopy make it possible to identify spectral contributions from each chemical constituent by a peak wavenumber comparison of single-component spectra (API and guest individually) and the two- component sample material …

Calcite cements in carbonates of the Sverdrup Basin, Canadian Arctic Archipelago.
… Archipelago) are the subject of this study. On a micro-scale, petrography with light microscopy, cathodoluminescence (CL), scanning electron microscopy (SEM) and staining helped to identify two main textural groups of cements, neomorphic and primary. Both are, in turn, subdivided into two …

On the development and application of a photon counting imaging system for broad spectrum luminescence analysis
… phenomena. In conjunction with novel micro-sampling and OSL site survey techniques, the PCIS may enable entirely new methodologies, transforming the role of luminescence in archaeology, palaeontology, and Quaternary geomorphology.

Microscopic Sampling of Dentine and Bone Collagen: Development of Sampling Methods for Carbon and Nitrogen Isotope Analysis
Sampling methods for dentine and bone collagen have been evolving for several decades. Incremental dentine collagen sampling and bone collagen sampling have been limited by the available technology throughout that time. As the technology for isotope ratio mass spectrometry analysis improves, the …
