Pericline twinning is a type of crystal twinning which show fine parallel twin laminae typically found in the alkali feldspars microcline.

The region has subsequently been deformed eight times ( see Pilbara Craton for details ), with the regional structure being a 30x20km pericline formed around the underlying granite dome.

The Axial Zone disappears in the Haut B�arn as a pericline underneath the Upper Cretaceous sedimentary cover only to reappear in the basement uplifts of Aldud�s-Quinto R�al, the southernmost of the Basque basement massifs.

In places these have been subjected to severe folding, as can been seen on the north coast near Crackington Haven, spectacularly at the " Whaleback Pericline " on the beach just south of Bude and at several other locations.
