PGP Research 

From 2006 onwards, PGP focuses on five core projects: Interface processes, the dynamics of microstructures, localization processes, fluid processes and the dynamics of plate margins. In a traditional geology department, these projects would be pursued in separate research groups, with little or no collaboration with scientists from other disciplines. However, the geological processes that these projects will elucidate are intimately coupled, and an integrated approach that takes these couplings fully into account is essential to the development of a comprehensive understanding of important geo-systems.

The coupling between fundamental processes across various time and length scales plays an important role in naturally systems, which are almost invariably complex. The linkage across scales leads to the emergence of spatial and temporal patterns, as cooperative phenomena. A comprehensive understanding of these cooperative phenomena is essential if we wish to explain the behaviour of systems with natural complexity, and develop ways of predicting and controlling their behaviour to protect the environment, secure natural resources and assess natural hazards. As it addresses more complex coupled multiscale systems, PGP will not lose its focus on basic science. We will not pursue complexity for its own sake, and we will focus on the development of conceptual and computer models that capture all the essential processes in a system without including processes that have little or no overall impact. The Figure shows how the five core projects are linked, with some of the most important feedbacks between the four scales. Fluids are unique in the sense that they play a key role at all scales – sometimes merely as a transport medium or agent, and sometimes as a chemically active ingredient. The coupling across scales and the role of fluids are common denominators in PGP research activities.
