Question: 1 / 400

In the context of geological structures, what does the term 'limbs' refer to?

The vertical portions of folds

The sides of a fold

The term 'limbs' in the context of geological structures specifically refers to the sides of a fold. In structural geology, when a rock layer is bent or deformed due to tectonic forces, it can create folds that consist of various components. The limbs are the sections that extend out from the hinge line, which is the area of maximum curvature in the fold. Each limb can vary in angle and orientation, contributing to the overall geometry of the fold.

Understanding the concept of limbs is crucial for interpreting geological maps and understanding the deformation history of an area, as the characteristics of the limbs can provide insight into the type of stresses that the rock has experienced.
