%X In the case of reverse drag of normal faulting, the
displacement and horizontal extension are determined based on the established
equations for the three mechanisms: rigid body, vertical shear and inclined
shear. There are three sub-cases of basal detachment for the rigid body model:
horizontal detachment, antithetic detachment and synthetic detachment. For the
rigid body model, the established equations indicate that the total
displacement on the synthetic base (<i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t2</span></sub><span style=\"font-family:Verdana;\">)
is</span><span style=\"font-family:Verdana;\"> the</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\"> largest, that on the horizontal base (</span><i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t1</span></sub><span style=\"font-family:Verdana;\">) is moderate, and that on the antithetic base (</span><i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t3</span></sub><span style=\"font-family:Verdana;\">) is </span></span><span style=\"font-family:Verdana;\">the </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">smallest. On the other hand,
the value of (</span><i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t1</span></sub><span style=\"font-family:Verdana;\">) is
larger than the displacement for the vertical shear (</span><i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t4</span></sub><span style=\"font-family:Verdana;\">). The value of (</span><i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t1</span></sub><span style=\"font-family:Verdana;\">)
is larger than or less than the displacement for the inclined shear (</span><i><span style=\"font-family:Verdana;\">D</span></i><sub><span style=\"font-family:Verdana;\">t5</span></sub><span style=\"font-family:Verdana;\">) depending on the
original fault dip </span><i><span style=\"font-family:Verdana;\">¦Ä</span></i><sub><span style=\"font-family:Verdana;\">0</span></sub><span style=\"font-family:Verdana;\">,
bedding angle </span><i><span style=\"font-family:Verdana;\">¦È</span></i><span style=\"font-family:Verdana;\">, and the angle of
shear direction</span></span><span style=\"font-family:&quot;\"> </span><i><span style=\"font-family:Verdana;\">¦Â</span></i><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">.
