see foldfold,
in geology, bent or deformed arrangement of stratified rocks. These rocks may be of sedimentary or volcanic origin. Although stratified rocks are normally deposited on the earth's surface in horizontal layers (see stratification), they are often found inclined or curved

a fold of stratified rocks which is convex upward. The bending point of the strata is called the anticlinal hinge. The surface connecting the bendings of all the strata composing the anticline is called the axial surface, and the sides of the anticline are called limbs. Depending on the position of the axial surface and the direction of the incline of the limbs, an anticline may be vertical, inclined, overturned, or recumbent. According to the configuration, it is possible to distinguish a linear anticline in which the lengtn is significantly greater than the width, a brachyanticline in which the length is somewhat greater than the width, and a dome in which the length and width are approximately equal.


A fold in which layered strata are inclined down and away from the axes.


a formation of stratified rock raised up, by folding, into a broad arch so that the strata slope down on both sides from a common crest
