Ductility (Earth science)
Videos
In Earth science, ductility refers to the capacity of a rock to deform to large strains without macroscopic fracturing. Such behavior may occur in unlithified or poorly lithified sediments, in weak ma
Fig. 1.0 – A vertical viewpoint of a rock outcrop that has undergone ductile deformation to create a series of asymmetric folds.
Overburden pressure

Pressure is force magnitude applied over an area. Overburden pressure is a geology term that denotes the pressure caused by the weight of the overlying layers of material at a specific depth under the

…sediments, in weak materials such as halite or at greater depths in all rock types where higher temperatures promote crystal plasticity and higher confining pressures suppress brittle fracture. In addition, when a material is behaving ductilely, it exhibits a linear stress vs strain relationship past the elastic…
Behavior of lithostatic pressure according to Heim's theory: it acts in all directions and causes a reduction in volume without deformation of the rocks
