What is it about?
We demonstrate, for the first time, that electrical resistivity tomography (ERT) profiles can be used to delineate subsurface fault-zone cementation. We also discovered the margin of a paleo-valley in the subsurface; it is an important control on the distribution of cementation.

Why is it important?
Delineating cemented fault zones in the subsurface is of practical interest, particularly given the ability of cemented fault zones to affect subsurface fluid flow.
