My researches is both theoretical and empirical. On the empirical side of things I am manager of the High-Pressure Petrology laboratory at St Andrews, and I collaborate with the STAiG laboratory and use the micro-analytical facilities available in the department of Earth and Environmental Sciences at St Andrews. Specific information about petrology and isotope geochemistry is provided below (with links). For a full list of our facilities follow this link.
We have a Rockland Piston Cylinder press capable of simulating pressures from 0.1-5 GPa and temperatures of 100-2000°C. This facility can be used to study solid-state, solid-fluid, or fluid-fluid reactions at high pressures and temperatures. Applications include elemental partitioning during differentiation of silicate melts, stable isotope fractionation during partitioning within planetary bodies, and the stability/degradation of organic carbon during metamorphism.
In the department of Earth and Environmental Sciences we host an Electron microprobe (equipped with light-element crystal for C-N determinations), two SEMs, XRD, XRF, Raman and NIR spectroscopy, and 2D-3D micro-imaging.
St Andrews Isotope Geochemistry (STAiG) laboratories
The STAiG laboratories consist of two Class-100 metal-free clean rooms for sample preparation and elemental purification as well as a variety of analytical facilities. These include an Agilent Quadrupole ICP-MS for elemental analysis, and three Multi-Collector ICP-MS (two Nu Plasma and one Thermo Scientific Neptune Plus instruments) for high-precision isotope analysis. We also have a 193nm Excimer Laser system for in-situ characterisation of samples. If you require isotope data or are interested in utilising our facilities please contact the lab managers (Drs Andrea Burke, James Rae, or Paul Savage).
Below is a periodic table showing our current systems, and the systems for which we can establish a protocol and make reliable measurements.
