Volcanology

Geology at Leicester, researches in many aspects of volcanology.  Over 12 of our research staff (listed below) have interests in a wide range of topics related to volcanic eruptions and magmatic processes in many different parts of the world, including the Antarctic peninsula, Korea, China, Mongolia, Siberia, Madagascar, East Greenland, Solomon Islands, Central Mexico, Hawaii, the English Lake District, the Faroes, Greece, Turkey, southern Italy, Canary islands, the Scotia Sea, and the Columbia River Basalts and Snake-River Plain regions of the western USA. Topics include emplacement of flood basalts, large explosive eruptions, pyroclastic density currents, magma-water and magma-ice interactions, volcanic instability and collapse, volcanic hydrothermal systems and mineralisation, and magma flow in lavas, sills and dykes. Our approaches range from analytical geochemistry (XRD, XRF, EMP, ICPMS and LA-ICPMS), isotope work (O, Hf, Ar-Ar, U-Pb), SEM and X-ray microtomography, fieldwork, petrogenesis, computer modelling, structural analysis, volcanic stratigraphy, seismic tomography of volcanoes, and laboratory experimentation.

We provide undergraduate and graduate training in several aspects of volcanology including laboratory work and annual residential field courses to Tenerife (Canary Islands), Mount Etna (Sicily) and the Scottish Tertiary Province (Skye, Arran), and post-graduate training in a variety of volcano locations. Our students also organise weekend field trips to study volcanic rocks of Snowdonia, the Lake District, and nearby Charnood Forest.
