From the economic points of view, petroleum deposits are found in porous sedimentary rocks that have been faulted against impervious shale beds. Folding and faulting are the most common deformation processes. Folding and faulting occur when pressure deep within the lithosphere cause the earth's surface to buckle, bend and even split apart. Geomorphic movements: large scale physical and chemical changes that take place on the earth’s surface due to geomorphic processes. Ø The large-scale movement maybe attributed to a major over thrusting or a recumbent folding followed by thrust faulting. This energy is mostly produced by rotational and tidal friction, radioactivity, and primordial heat from the origin of the earth. 10.
