Reconstruction of aspects of Northern New Zealand paleoclimate over the last 200 ka using laminated Auckland maar lake sequences
… history of Onepoto maar lake using μ-XRF core scanning, dry bulk density, loss-on-ignition measurements, and visual lithostratigraphic descriptions. As another aspect of this work, a multi-method high-resolution study of deep Ōrākei maar lake sediment micro-facies represents a first of …

A 210,000-year reconstruction of subtropical climates from Fern Gully Lagoon, North Stradbroke Island (Minjerribah), Australia
… agedepth modelling (Chapter 3). • Scanning micro-X-ray fluorescence geochemical analysis of Fern Gully Lagoon sediments, enabling a record of inorganic dust flux to be created and regional moisture availability for subtropical eastern Australia to be inferred for the past ~210 kyr (Chapter …

Investigations on rainfall variability during the late Quaternary based on geochemical analyses of lake sediments from tropical and subtropical southern Africa
… laminated sediments which were analyses with micro-XRF scanning for changes in the element composition. By comparing these results with investigations on thin sections, results from ongoing sediment trap studies, meteorological data, and investigations on the surrounding rocks and soils, I …

Petrogenesis of the Mesoproterozoic anorthosite, syenite and carbonatite suites of NW Namibia and their contribution to the metasomatic formation of the Swartbooisdrif sodalite deposits
… analyses and fluid inclusion measurements (microthermometrical studies and synchrotron-micro-XRF analyses) have been combined. There is striking evidence that carbonatites of both generations are magmatic in origin. They occur as dykes with cross-cutting relationships and margins disturbed …
