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).
