Construct Fault under Rollover Anticline

Construct Fault under Rollover Anticline

Rollover anticlines are common types of folds in extensional basins. The shape of the rollover is related to the shape of the underlying listric fault. This is useful to know as the fault may be poorly imaged.

Here we describe a simple (by hand) construction that can be performed on a seismic section - to reduce interpretation uncertainty
