The Applied Geosciences research and enterprise group combines the research interests of researchers and PhD students working on fundamental geological and earth surface processes, and their application to environmental and resource management. Areas of expertise within the group include environmental nanotechnology, geochemistry, hydrology and hydrogeology, mineral deposits, sedimentology and geomorphology.

The group’s pure and applied research is aligned closely to industrial and business needs, with funding from a range of sources including research councils, the European Union, charities and industry. Members of the group are also active participants in the Centre for Aquatic Environments, and the Ecosystems, Remote Sensing and Environmental Management and Past Human and Environmental Dynamics research groups.

Research within the group falls under the following themes:

Past and present sediment dynamics
Applied geochemistry
Metcycle - Geosphere to Biosphere metal cycling

Past and present sediment dynamics

Research within this theme focuses upon understanding the dynamics of fluvial, estuarine and other coastal sediments, and applying this understanding to environmental and natural resource management. Our work has two main foci: understanding contemporary and past landscape processes, and the quantification and modelling of sediment morphodynamics.

Research by the members spans a range of scales, including work in some of the largest rivers and estuaries in the world. Current projects include analyses of river bedform structures and dynamics in unsteady flows, and modelling how sediment suspension controls the morphology of sand-bed rivers. Group members also employ techniques such as radiometric dating and geochemical analysis to unravel coastal and estuarine sediment records of storms, tsunamis, and coastal neo-tectonics.

The majority of our work has real-world application. Research by AGRG members is, for example, being used in the characterisation of hydrocarbon reservoirs, in estuarine management, for improving flood prediction, and in the engineering of managed retreat sites.

Applied geochemistry

Research within this theme focuses on nanogeoscience, contaminated land remediation, carbonate mineralogy for CO₂ sequestration applications, the genesis of mineral resources, hydrogeology and igneous petrology. Our research addresses water flow and the geochemistry of contaminants in soil and groundwater, the genesis of geological resources, and the global scale implications of igneous processes.

Examples of current work include investigations into the formation of rare earth element (REE) mineral resources, the development of new technologies for the remediation of contaminated land, the spectroscopic investigation of minerals used in CO₂ sequestration, and the flow and transport properties of groundwater in chalk aquifers. Work in igneous petrology is focusing on the impact of large igneous provinces on the development of the global environment.

The work undertaken by the group is strongly applied in nature, ranging from ensuring the environmentally acceptable supply of REEs necessary for low carbon energy production, to the development of remediation measures for contaminated land.

MetCycle: Geosphere to Biosphere metal cycling

A range of metals that are vital to high technology and renewable energy generation have recently been classified as ‘critical’ for the UK and EU economies because of potential risks to their supply as raw materials, and the potential economic impact of supply failure. The MetCycle theme brings together staff with international expertise in mineral deposit genesis, environmental fate of metals and clean-up of metal-contaminated environments to address key research challenges in this internationally expanding area.

Understanding the behaviour of individual metallic elements in geological, environmental and biological systems is a basic underpinning of modern society and the way in which we deal with our environmental impact. Metals used to meet societal needs are derived from accumulations formed by geological processes, are dispersed to the environment via atmospheric, aquatic and biological processes, and require remediation from waste either to mitigate their environmental impact, or to enhance their recovery to contribute to sustainable development.

This theme combines researchers with interests in conventional mineral deposit formation, critical metal deposits, trace element behaviour in geological processes, sediment biogeochemistry, contaminated land and atmospheric particulates. It is directly supported by facilities for ICP-MS analyses (Agilent 7900) and sample preparation, and by School of Environment and Technology facilities for portable and laboratory X-ray Fluorescence, ICP-OES, X-ray diffraction, ion chromatography, and gamma spectrometry.
