Next-Generation Petrochronology Using Triple-Stream Femtosecond Laser Ablation ICP-MS University of Glasgow in United Kingdom

This PhD opportunity at the University of Glasgow invites an outstanding candidate to develop next-generation petrochronology methods using a triple-stream femtosecond laser ablation ICP-MS platform. The project integrates advanced laser ablation technology with three Thermo Fisher Scientific mass spectrometers, enabling simultaneous measurement of multiple isotopic and geochemical systems from the same microscopic domains in minerals.

Petrochronology, which combines geochronology with trace element and isotopic information recorded in minerals, is revolutionizing how geoscientists reconstruct the timing and evolution of geological processes. By linking age information with chemical signatures that record magma evolution, temperature, and crustal interaction, this approach allows the dynamics of Earth processes to be resolved at unprecedented spatial and temporal resolution. However, most current workflows require separate analyses for age, isotopes, and trace elements, limiting spatial resolution and preventing direct comparison of signals recorded in the same mineral growth domains.

This project will develop an integrated analytical platform capable of simultaneous multi-isotope petrochronology by splitting a single femtosecond laser aerosol stream into three independent ICP-MS instruments: the Thermo Scientific Neoma MC-ICP-MS for high-precision Hf isotope measurements, the Thermo Scientific Element HR-ICP-MS for U–Pb geochronology, and the Thermo Scientific iCAP TQ MTX triple quadrupole ICP-MS for trace element analysis and interference-resolved isotope measurements. This configuration will allow U–Pb ages, Hf isotopes, and trace element signatures to be measured simultaneously from the same micron-scale ablation volume, providing a powerful new capability for petrochronology.

The PhD student will design and optimize the analytical architecture required to deliver this capability, including developing aerosol splitting systems, gas flow dynamics, ion transport optimization, analytical protocols, and data reduction frameworks. Once established, the platform will be applied to eroded plutonic systems across Scotland, which offer an exceptional natural laboratory for petrochronology. Scotland exposes deeply eroded intrusive complexes associated with the Caledonian orogeny, allowing direct access to the roots of ancient magmatic systems rarely preserved elsewhere. These rocks provide an ideal opportunity to investigate the assembly, evolution, and crustal architecture of continental magmatic systems.

Using zircon petrochronology, the project will address key questions such as how Scottish plutons were assembled through time, whether magma bodies formed incrementally or during short-lived emplacement events, how mantle-derived magmas interacted with the continental crust, and how magmatic systems evolved during the Caledonian mountain-building event. By linking U–Pb ages, Hf isotopes, and trace element signatures directly within zircon growth domains, the project will provide new insights into the timescales and processes of crustal magmatism and demonstrate the power of next-generation petrochronology methods.

The student will work within a cutting-edge analytical environment at SUERC (Centre for Isotope Science), located in East Kilbride, about 20 km from the main University of Glasgow campus. There will also be opportunities to spend extended periods embedded within Thermo Fisher Scientific’s Research and Development hub in Bremen, Germany, working directly with engineers and scientists developing the next generation of mass spectrometry platforms. The successful candidate will join a cohort of six PhD students forming a focused mini-CDT, dedicated to developing next-generation analytical technologies across multiple isotope systems and advancing new approaches in geochronology.

The studentship provides full financial support, including payment of academic tuition fees, a UKRI-aligned stipend for 42 months, and coverage of all laboratory and research travel costs. The project is open to applicants from around the world. Applicants should have strong backgrounds in geochemistry, Earth sciences, analytical chemistry, physics, or engineering. Experience with mass spectrometry, laser ablation, instrumentation, or data analysis is advantageous but not essential, as full training will be provided within a world-leading isotope research environment.
