The School of Geography, Earth and Environmental Sciences organises a regular series of research seminars throughout the academic year to which everyone is welcome to attend. Speakers - both external and internal to the University - will talk on topics related to all aspects of Earth Sciences.
Today's speaker is Professor Bruce Yardley from the University of Leeds.
Fluids are fundamental to the way that the Earth’s crust behaves. They dictate its physical properties as essential participants in rock deformation and they are responsible for moving and concentrating chemical elements to form mineral resources. Without fluids, and in particular water, our planet would be dead.
In this lecture Bruce will introduce the fluids that may occur in different parts of the crust and discuss the ways in which they interact with rocks and evolve from burial of sediments though deep crustal process to exhumation and erosion. On the face of it, crustal fluids is a complex topic with many possible variables that might change how they behave. Fortunately, many of these variables do not act independently; they change in predictable ways so that the rocks produced through the cycle of orogeny have been very similar in many different locations over much of geological time.
