Question
What is a limb and hinge line?
Kashif,
These two terms are used to describe geometric elements of folded rocks. To help you visualize the meaning of these terms lets do a simple demonstration. Take a sheet of paper and fold it in half. Each flat half of the sheet is a fold limb. The hinge line is the crease where you have folded it.
