WebA compressive stress compacts horizontal rock layers and forces them to bend vertically, forming fold patterns. Anticlines and synclines. An anticline is a fold that is arched upward to form a ridge; a syncline is a fold that arches downward to form a trough (Figure ). Anticlines and synclines are usually made up of many rock units that are ... WebFolds are described by the orientation of their axes, axial planes, and limbs. They are made up of two or more dipping beds in opposite directions, which come together along a line called the axis. Each set of dipping beds is known as a fold limb.
