Georg Zellmer received his PhD from the Open University, UK, in 1999, and worked as postdoctoral fellow at the University of Bristol, the Lamont-Doherty Earth Observatory (Columbia Univeristy) and the University of Hawaii. Before arriving at Massey University in 2013, he spent 8 years on the Earth Sciences faculty at Academia Sinica, Taipei. Georg's interests include volcanology, igneous petrology, and high-temperature geochemistry, with emphasis on geochemical techniques to decipher magmatic evolution in a range of tectonic settings. His work focuses on timescales of petrogenesis, volatile cycling through subduction zones, and linking geophysical and geochemical observations at global destructive plate margins.

Project Title: Mitigating volcanic hazards through advanced technologies

The key question asked of a volcano monitoring agency is: "When will the volcano erupt?" This question is very difficult to answer, because the interpretation of monitoring signals requires a good understanding of the magmatic processes that lead to an eruption. Here we take advantage of the record of these processes preserved in previously erupted materials in the form of crystals grown in the magma, within a variable (pressure, temperature, chemical etc.) environment. Using high resolution analysis, it is possible to forensically examine these variations, and combined with experimentally determined element diffusion rates, we will be able to quantitatively determine the rates and timing of events that led to the eruption.This project will employ advanced secondary ion mass spectrometry methods at the Isotope Imaging Laboratory at the University of Hokkaido to image and quantify the chemical variations within crystals and between crystals and surrounding volcanic glass, to decipher crystal growth and resorption histories. In doing so, we will be able to constrain the storage history and ascent rates of magma before the onset of explosive volcanic eruptions. The results from this work will be directly applicable to the applied monitoring of New Zealand's volcanoes and incorporated into the GeoNet project. Such high-resolution analysis of a wide range of major and trace elements in submicrometer detail, as well as providing quantitative measurements of isotopic composition for precise geochronological work, is unique worldwide. This will be the first time that a team of New Zealand based experts in geochemical methods to characterize volcanic hazards gains access to this powerful set of tools. The project will strengthen existing contacts between New Zealand based scientists and colleagues in Japan, especially at the University of Hokkaido, and will provide a foundation for many years of productive international collaboration in the interest of public safety

Project Title: Dynamics of magma ascent beneath New Zealand's subduction zone volcanoes: implications for hazard mitigation strategies

Hazard mitigation strategies at subduction zone volcanoes critically depend on knowledge of magma ascent processes and rates. Two diametrically opposite scenarios have been debated in recent years: 1. Protracted sub-liquidus magma ascent and evolution through crystal growth and fractionation in crustal reservoirs that are tapped during volcanic eruptions. This represents the long-standing paradigm of subvolcanic magma chambers characterized by cooling and occasional recharge with new melts. 2. Rapid decompression of evolved mantle melts from the crust-mantle boundary to the surface under super-liquidus conditions, with crystals in the process of dissolving. In the latter model, hydrous melts traverse the Earth's crust to reach the surface within hours to days. Their rapid ascent initially results in superheating, because these melts cannot degas before reaching upper crustal levels. Which of these scenarios best explains subduction zone volcanism on Earth? We will characterize the geochemical signature of melt boundary layers at crystal-melt interfaces and thereby determine if crystals were in the process of growing or dissolving at the onset of volcanic eruptions. In the case of crystal growth, the melt boundary layer will be depleted in mineral-forming chemical components; in the case of crystal dissolution, this layer will become enriched in such components. To quantify crystal dissolution rates, we will conduct dissolution experiments using piston cylinders to subject crystal-bearing hydrous melts to superliquidus temperatures. We will then compare the experimental results to data from natural samples from New Zealands active volcanoes. This will allow us to quantify magma ascent processes and rates in nature.
