1. Characterising volcanic magma plumbing systems : A tool to improve eruption forecasting at hazardous volcanoes
Sammanfattning : This thesis attempts to develop our understanding of volcanic magma plumbing systems and the magmatic processes that operate within them, such as fractional crystallisation, crustal partial melting, assimilation, and magma mixing. I utilise petrology, rock and mineral geochemistry, and isotope systematics to seek to improve our ability to forecast the eruptive frequency and style of active volcanoes, an aspect often lacking in current volcano monitoring efforts.

2. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia
Sammanfattning : The remote lower Cambrian Byrd group of sedimentary rocks from East Antarctica has been studied intermittently since its discovery over a century ago. Previous insights into the trilobites and archaeocyaths indicated a close correlation to the sedimentary sequences of South Australia. LÄS MER
