This paper was perhaps the first attempt to apply the concepts of recumbent folding and nappe structure to geologic interpretation of the piedmont.
2.
The Alpine orogeny occurred in ongoing cycles through to the Paleogene causing differences in nappe structures, with a late-stage orogeny causing the development of the Jura Mountains.

The collision events in the Belomorian Province are represented by high pressure ( 6 12 kbar ) and high temperature ( 500 700�C ) kyanite-facies metamorphism, granitoid magmatism, and the formation of folded nappe structure and granite gneiss domes.
