Geochemistry
We focus on tracing Earth system processes at both low and high temperature using geochemical methods.
We build upon the varied and highly complementary expertise in geochemistry across the School of Earth and Ocean Sciences to foster new collaborative projects.
Our group also showcases the unique capacity of the School in analytical geochemistry to the rest of the UK community.
Aims
We aim to tackle some of the most important questions in Earth Sciences.
- How did Earth's continents form?
- How did the Earth's surface become oxygen-rich?
- The nature of mantle compositional heterogeneities.
- Causes and consequences of Earth's changing climate.
- Tracing ocean circulation through time.
- Magmatic and eruptive processes.
- Weathering and the carbon cycle.

Isotope lab
The lab hosts a Nu Plasma II MC-ICP-MS (delivery Oct 2016), an Element 2 XR ICP-MS and an Excimer Laser Ablation System. It also comprises of 2 class 1000 clean rooms dedicated for low blank processing of geological samples for isotope measurements.
ELEMENT Facility for Geochemical Fingerprinting of Earth Materials
The facility was originally set up under NERC award NER/H/S/2000/00862 (£546k) and has recently been upgraded by a new award from Cardiff University Research Infrastructure Fund.
The suite of instruments comprises: two Thermo iCAP RQ quadropole ICP-MS spectrometers, a Thermo iCAP ICP-OES spectrometer, a 213nm laser ablation system, a micromill and microbalance and an Olympus Delta Pro portable XRF spectrometer.
Dedicated fire assay laboratory
The laboratory supports analysis of precious metals in rocks, ores and other environmental samples. We also have a Wet geochemistry laboratory for preparation of samples in liquid form for ICP analysis.
Zeiss Sigma HD Field Emission Gun Analytical SEM
High-resolution imaging and X-ray element mapping as well as quantitative analysis of major, minor and trace elements. FEI XL30 Field Emission Gun Environmental SEM for high-resolution imaging and semi-quantitative X-ray element analysis of samples. Philips PW1710 Automated Powder X-ray diffractometer.
Stable isotope facility
The facility is equipped with a Finnigan MAT 252 and 253 mass spectrometer attached to a Kiel carbonate device, and Delta V advantage mass-spectrometer coupled with a GasBench-II and Flash EFCt Elemental Analyser.
