The first step toward 3-D interpretation of a 3-D volume is to use time slices. The value of time-slice interpretation for faults is fairly obvious. Regardless of the strike of the fault, most fault surfaces intersect the time slice at an angle between 45° and 90° to the plane of the time slice

Depositional systems are typically more interpretable on time slices than they are on vertical sections. [[:file:interpreting-3-d-seismic-data_fig13-3.png|Figure 2]] is a time slice from a 3-D survey in the North Sea. Aportion of a braided stream system is clearly evident.
