Royal Holloway

On August 25, Senior Research Fellow Frank Peel served on the examining committee for Ph.D. student Heraclio Gutierrez-Moreno at Royal Holloway University.

Frank Peel recently spent some time in the field looking at evaporite tectonics in the internal French Alps. In the picture at the left, Frank is standing in front of a gypsum diapir exposed in the Col du Souffre, Vanoise, France. The Triassic salt in the diapir is piercing upward into older Carboniferous strata, as a consequence of being on the overturned limb of an Alpine fold.
