Abstract
A number of geometrical techniques allow estimating amounts of horizontal extension and depth to detachment in simple rollover anticlines over listric normal faults given one or more horizons, the portion of the fault between the hanging wall and foot wall cut off points, and the depth to detachment (if the extension is to be estimated) or the extension (if the depth to detachment is to be estimated). These techniques assist in the construction and validation of sections across listric normal faults, but currently, it is unclear which ones predict correct amounts of horizontal extension and detachment depth and why is that. To sort this out, these techniques are evaluated using physical experiments and subsurface seismic examples of simple listric normal faults.
