FIELD GEOLGY

 

One way to investigate how the earth deforms is to look at: (1) The cumulative effect of the deformation once a fault is exhumed and is extensively exposed, or (2) How structures and other features such as alteration or fluid flow are spatially and temporally associated.

Both of these approaches allow us to see a great deal of the detail and variation in fault zones. However, in most cases faults exposed in this way are no longer active and we cannot directly observe the stresses or tectonic displacements that drove the deformation.
