E. Folds – Geological Structures: a Practical Introduction

WebThese folds give us features such as synclines and anticlines where Earth’s crust has folded up like an accordion as a result of compressional stress. In the case of synclines, the folds point upward from the central axis, or "hinge line", whereas in an anticline, the folds point downward from the central axis. WebAnticlines are a common fold type found in the Earth’s crust. When upright, the limbs (flat inclined surfaces) of these folds dip away from the axial surface (the plane intersecting the maximum curvature of the fold) to form a concave-downward structure. More generally, any type of fold that has this geometry is called an antiform. irey vaughan
