Simple-Shear Restoration
Page 1/1
Restore the growth normal fault in Fig. 11.74. This section contains growth stratigraphy and can be sequentially restored to the regional for horizons 2 and 3 to show the growth history. Why is the simpleshear method a reasonable choice? What is the appropriate choice of the regional? What is the most
appropriate shear angle and how do you find it? Is the cross section valid?
