In structural geology, what is the term for a fracture along which there has been significant displacement of the rock masses parallel to the fracture plane?

💡 Solution & Explanation

A fault is a fracture in geological rock strata along which considerable displacement has taken place parallel to the plane of the fracture, distinguishing it from joints where no movement occurs. These tectonic structures are categorized based on their movement vectors into normal, reverse, and strike-slip faults.
