Monocline
A monocline is a form of homocline in which the local rock layers form a flexure and run in steps.
Emergence
Two basic forms of the formation of monoclines are known, whereby in both cases a superimposed warp is the cause.
Mainly at the edge of large basin structures filled with sediment , a compaction of older deposits filling this basin under the load of younger layers along a fault leads to a monocline in this overburden.
If during the course of geological activity along an existing, from a waste , up or thrust resulting drag fold it affected lying layers, usually a step formed in the overburden. This type of monocline is also known as drape fold or forced fold .
By bending , compression , shear and buckling of the layers of rock affected differences arise in the arrangement of individual layers within the monoclinal.
