Tectonics and Geophysics

We investigate the physical processes of the solid Earth.

The Tectonics and Geophysics Research Group researches the breadth of tectonics and magmatism from rapid events such as earthquakes and volcanic eruptions, to slower processes such as solid-state creep and magma flow, and longer time scale processes that shape Earth's crust by deep crustal and mantle deformation.

We use field research, laboratory analysis and numerical modelling to understand dynamic processes occurring in Earth's interior from near-surface to deepest mantle. This work feeds into research priorities in geohazards, deformation of Earth materials and computational Earth sciences.

Aims

We aim to understand the causes and consequences of the dynamic processes changing the solid Earth by using our expertise in structural geology, petrology, geophysics, tectonics and geodynamics.

Tom Blenkinsop, David Buchs, Ake Fagereng, Huw Davies and Chris MacLeod lead this area, investigating the physical processes of the solid Earth using field observations, laboratory analyses, geophysical observations and numerical modelling.

Our research ranges from crustal fault behaviour and fluid flow to the deformation of the mantle, from microscopic to global scales.

Our three focus areas are:

  • volcanic, sedimentary and tectonic processes at convergent and divergent margins
  • fault mechanics and microstructures
  • early Earth tectonics.

We examine how faults accommodate slip, seismically and aseismically, and how the range in geophysically observed fault behaviours may be recorded in exhumed rocks, using examples from contractional, extension and strike-slip tectonic regimes.

Magmatism and tectonics

Our research focuses on the formation and evolution of the lithosphere in a variety of oceanic and continental settings. These are split into four areas:

We adopt a multidisciplinary approach, mostly based on fieldwork on land and at sea (including ocean drilling), using a combination of geochemical/petrological modelling, structural geology and geophysics.

Processes of particular interest to us include:

  • magma generation in the sub-oceanic mantle
  • crustal accretion at mid-ocean ridges
  • deformation of the oceanic lithosphere
  • formation of seamounts and oceanic islands
  • formation of oceanic plateaus and continental flood basalts and their environmental impacts
  • hydrothermal processes
  • subduction initiation and the formation of ophiolites.

Mantle geodynamics

Led by Huw Davies, we are interested in understanding how mantle dynamics drive plate tectonics and control planetary evolution using global and regional numerical simulations constrained by observations. Processes of interest include subduction, upwelling plumes and mantle convection. Much of our numerical simulations are undertaken on large clusters including, the University cluster run by Advanced Research Computing at Cardiff (ARCCA), and the UK Supercomputer, Archer2.
