Orogenic Evolution

Orogenic Evolution (bottom up)

Even today few Earth Scientists appreciate that the continents, in different places and at different times in Earth history, have experienced extreme metamorphism at temperatures of over 1000oC and yet have survived the thermal shock. The resulting Ultrahigh temperature (UHT) metamorphic belts provide vital clues as to how the deep continental crust of the Earth forms and evolves in response to tectonics.

Using a combination of field, experimental and microanalytical approaches, Edinburgh geoscientists are world leaders in research into UHT and its causes. We aim to define not only the physical conditions, ages and timescales of UHT but also the complex interplay of chemical and physical processes that dictate how the hottest deep crust behaves when continents collide.

Research interests focus on:

1) The rates and styles of surface processes that erode mountain belts and that deposit and accumulate sediments in the surrounding sedimentary basins. 2) How these processes couple to the tectonic forcing of mountain building and sedimentary basin development, particularly that of foreland basins. 3) The differentiation of tectonic versus climatic forcing of mountain belts and their surrounding foreland basins.
