Isotope Systematics of Gypsum and its Hydration Water
… isotope analysis of the structurally-bound water in gypsum can provide a direct measure of past hydrologic variability. This thesis presents the development of the water extraction and isotopic measurement procedures, the calculation of the gypsum-water isotope fractionation factors, and the …

A Multi-Archive Reconstruction of Holocene Summer and Winter Monsoon Variability in NW South Asia
… core 63KA over 8.8-7.6 ka BP and 5.4-3.0 ka BP, gypsum from three Holocene Thar Desert playa lakes, and sub-annually resolved trace element and stable isotope data from DHAR-1 speleothem covering 4.2-2.5 ka BP. The major findings from this thesis contribute to a more comprehensive understanding …

Application of Hydrogen and Oxygen Isotope Ratios of Water to the Study of Evaporation, Palaeoclimate, and Ancient Marine Conditions
Triple-oxygen and hydrogen isotopes of water are critical to aid our understanding of the hydrological cycle on the modern and ancient Earth. As such, this thesis presents advancements in techniques and in the understanding of the isotopic behaviour of water that undergoes evaporation in different …

Emerging stable isotope techniques in hydrothermal research: new methods applied to carbonates and hydrous minerals in ore deposits and geothermal fields
… rock assay pulps using a custom-built thermal dehydration-dehydroxylation Off-Axis Integrated Cavity Output Spectroscopy (TD-OA-ICOS) system. The δ2H methodology presented is equal to isotope ratio mass spectrometry in terms of speed and precision, but considerably lower in cost. This work …
