In geology, a large body or sheet of rock that has been moved by faulting or folding a distance of about 1 mi (1.5 km) or more from its original position. A nappe may be the hanging wall of a low-angle thrust fault (a fracture in the rocks of the Earth's crust caused by contraction), or it may be a large recumbent fold (i.e., an undulation in the stratified rocks that have an essentially horizontal axial plane); both processes position older rocks over younger rocks.

A sheet of rocks, part of a broken recumbent fold which has been moved forward over the rock formations beneath and in front of it, finally covering them. Nappes are typical of most mountains of the Alpine type of structure; the western Alps display a complex series of nappes, formed when the African foreland was pushed northwards against the European foreland.

IN BRIEF: n. - One of the two sheets that make up a cone shape.
Tutor's tip: The woodpecker's "knap" ( sharp rap or strike) nipped my "nap" (short sleep) just as spray from the "nappe" (water overflow of a dam) hit my "nape" (back part of the neck).

The quality or thickness of a sauce, its viscosity. Nappé is measured usually by dipping a non-porous wooden spoon into the liquid and running a finger down the length of the spoon's convex side. If the line remains and does not come together, the nappé is good. Another method is the drizzle method. Here some chefs drizzle the sauce into itself to see how quickly the drizzle dots coalesce into the sauce. See Culinary Arts, Viscosity.
