Acknowledgements

Earlier fieldwork for this study was financed by postdoctoral scholarship from the Graduiertenkolleg "Stoffbestand und Entwicklung von Kruste und Mantel" and a postdoctoral scholarship of the Deutsche Forschungsgemeinschaft, both at the Johannes-Gutenberg-University at Mainz. I am grateful to Cees Passchier for introducing me to the Pyrenean geology.
