What is a periclinal fold?

Periclinal folds are a type of anticlines that have a well-defined, but curved hinge line and are doubly plunging and thus elongate domes. What is the difference between an anticline and a syncline?

What is an anticline fold?

• Anticline –A fold in the form of an arch, with the rock strata convex upward and the older rocks in the core Monocline Parts of a fold

What is a periclinal structure?

scale antiforms or synforms whose amplitude decreases - regularly to zero in both directions so that the fold has precise limits in space. Domes and basins are periclinal structures. Aspect ratio The aspect ratio

What are polyclinal folds?

Polyclinal folds belong to groups of folds with sub- parallel hinge lines but non -parallel axial surfaces. Layer thickness - parallel and similar folds Changes in layer thicknesses reflect the material properties of the fold.
