Research Group: Geochemistry

Currently Active: 
Yes

Geochemistry comprises more than 30 researchers and postgraduate students who apply state-of-the-art geochemical analysis and modelling to scientific questions of major societal, economic and environmental importance.

Our diverse research activity can be broadly divided into 8 themes. Click the theme title for more information.

Past Present and Future Environmental Change

  • We aim to achieve a better understanding of the major geochemical cycles of the Earth System and the impact of humanities action upon them. Our work also focuses on the reconstruction of the climate of the past to better understand the drivers of natural climate and environmental change.

Environmental Geochemistry and Radioactivity

  • Research into how we interact with our environment and its impact on us
  • Encompasses specialist radioanalytical research and specialist services offered by our Industrial Advisory Unit, GAU-Radioanalytical

Volcanic Processes

  • Volcanoes are the points at the surface where material is exchanged between the inner Earth and the world we live in

Hydrothermal Processes and Mineral Deposits

  • Hydrothermal processes represent one of the major mechanisms for chemical and heat transfer on Earth. They have a profound influence on ocean chemistry and they play host to unique ecosystems. In addition many of the world's most important resources are sourced from deposits that formed as a result of hydrothermal activity.

Formation and Evolution of the Ocean Crust

  • The accretion of new crust at the mid-ocean ridges is the foundation process of the plate tectonic cycle

Medical Geochemistry

  • Geochemistry can play a valuable role in the study of environmental health issues

Geochemical Ecology

  • The geochemical ecology (Southampton University Marine Isotopes and Ecology SUMIE) group use natural chemical markers contained in the tissues of animals to track the flow of nutrients within food webs and the movement of animals across geochemical gradients.

Carbon Storage and Geoengineering

  • We are working to find solutions to reducing levels of carbon dioxide (CO2) in the atmosphere. These include storage in conventional (depleted oil and gas reservoirs, deep saline aquifers) and unconventional (basalts, mantle peridotites, enhanced weathering) geological reservoirs.

Our strengths include:

  • ultra-low level trace element analyses
  • radiogenic isotope geochemistry and geochronology
  • fluid and volatile analysis
  • environmental radiochemistry
  • geochemical ecology and biominerals
  • speciation and reaction modelling
  • analytical technique development and refinement

Contact: Dr Juerg Matter

The Geochemistry Group is equipped with a world-class range of analytical equipment and associated laboratories. The instruments and techniques available can be applied to a diverse range of applications including environmental, geological, nuclear, medical, archaeological and oceanographic. The facility is used for a wide range of research purposes and also for commercial analysis, examples of the type of commercial work we can under take are given here.

The facilities available are briefly described below and further details are available on each by clicking on the links.

For initial enquiries about our capability or using the facilities contact Dr. J. Andy Milton

Quadrupole ICP-MS: Thermo X-SERIES 2

This instrument is used for high-throughput elemental analysis via solution or solid sample introduction using the laser.

High Resolution ICP-MS: Thermo ELEMENT 2XR

This is a high-sensitivity elemental and isotopic analysis instrument for solution or solid samples using the laser. It is particularly suited to difficult matrix and problematic elemental analyses.

Multi-collector ICP-MS: Thermo NEPTUNE

We have two of these high-sensitivity isotope analysis instruments allowing analysis of solutions or solid samples using the laser. Currently measuring the following systems: Li, B, Cr, Fe, Sr, Nd, Pb, Hf, U, U-Pb, U-Th and Pu.

Thermal Ionisation: Thermo TRITON

This instrument provides high precision isotope analysis on samples that have been loaded onto a metal filament. Currently measuring the following systems: Sr, Nd, Pb.

Laser Ablation: New Wave UP193FX

This laser system is used for micro-sampling of solid samples it can be coupled to any ICP-MS systems above.

Micro drill: New Wave Micromill

For preparing micro-sized samples for subsequent analysis.

Clean Chemistry Laboratories

A suite of Class 100 chemistry labs for sample preparation prior to analysis.

Commercial Sample Analysis

The Geochemistry group is able to help you analyse your samples.

GAU-Radioanalytical (GAU)

Specialist analytical facilities.
