The dip of a reverse fault is relatively steep greater than 45. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments. The hanging wall moves up and over the footwall. The mass of rock overlying a mineral deposit in a mine.

The line it makes on the earth s surface is the fault trace. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. The underlying block of a fault having an inclined fault plane. The terminology of normal and reverse comes from coal mining in england where normal faults are the most common.

The fault strike is the direction of the line of intersection between the fault plane and earth s surface. Reverse faults indicate compressive shortening of the crust. Thrust faults are reverse faults that dip less than 45. These are often found in intensely deformed.
