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 GAU-Radioanalytical which is a major provider of radioanalytical expertise to the environmental and nuclear industries as well as state-of-the-art geochemical facilities providing material characterisation from the bulk to the nano-scale. These facilities also support our National Nuclear Users Facility in next generation accelerated characterisation technologies (NNUF-EXACT).

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: Professor Gavin Foster

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. For examples of commercial activities please click here.

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

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

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.

Triple Quadrupole ICP-MS: Agilent 8900

This second-generation ICP-QQQ (or ICP-MS/MS) has a range of configurations to cover applications from routine analyse to advanced research and high-performance materials analysis via solution or laser ablation mode.

High Resolution ICP-MS: Thermo Scientific Element XR

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.

Time of Flight ICP-MS: Nu Instruments Vitesse

The ICP Time of Flight (TOF) mass spectrometer has the ability to collect complete mass spectra at >33,000 per second. This ultra-rapid, wide mass range acquisition is ideal for applications such as laser ablation imaging and nanoparticle analysis.

Thermal Ionisation: Thermo Scientific Triton Plus

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.

Multi-collector ICP-MS: Thermo Scientific NEPTUNE and Neptune Plus

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.

Laser Ablation: ESI Lasers NWR193 and UP213

These two laser ablation systems can be used for micro-sampling of solid samples coupled to any of our ICP systems (including the TOF).

Micro drill: New Wave Micromill

For the precise micron-scale sampling of solid materials for subsequent geochemical and/or isotopic analysis.

Clean Chemistry Laboratories

A suite of Class 100 chemistry laboratories for sample preparation and purification prior to geochemical and/or isotopic analysis. Take a tour of our facilities below.

Particle Characterisation: Asymmetric Flow Field-Flow Fractionation (AF4)

This system is capable of characterising the size of nanoparticles, polymers, and proteins (ranging in size from 1nm to 10microns) via a chromatography-like elution technique.  It can be coupled to a wide range of instruments such as our range of ICP.

Carbon Sequestration Laboratory

A wet chemistry lab facility to study water-rock interaction processes related to carbon capture and storage.

Organic Geochemistry Laboratories

Hosts a dedicated sample preparation lab, wet chemistry lab space, and an instrumentation facility designed to characterise organic matter from the environment and the geological record.

GAU-Radioanalytical (GAU)

GAU-Radioanlytical Laboratories is a long established commercial group providing radioanalytical services, consultancy and research support for government, industrial (nuclear and environmental) and academic sectors.

NNUF-EXACT

NNUF-EXACT (Next Generation Accelerated Characterisation Technologies) is part of the National Nuclear Users Facility enabling research and training in accelerated nuclear characterisation and remediation technologies underpinning civil nuclear programmes, decommissioning and site clean-up and new nuclear infrastructure.
