A classic example from Great Britain is that of the inlier of folded Ordovician and Silurian rocks at Horton in Ribblesdale in North Yorkshire which are surrounded by the younger flat-lying Carboniferous Limestone.
This is isolated from the very much larger area of Triassic rocks which characterise the English Midlands and Cheshire Basin, to the south and west respectively, by the surrounding Carboniferous sandstones and mudstones.
Similarly in the Black Mountains of South Wales, the summit area of Pen Cerrig-calch is composed from a suite of Carboniferous age sandstones and limestone.
[2][3] In West Africa, the Kenieba inlier borders southwestern Mali and eastern Senegal, and associated Birimian gold is found in Kalana and Sabodala respectively.
[4] A similar isolated arrangement of rocks produced for example by movement on a thrust fault followed by erosion may be termed a klippe.
