Exercise 6.9.2
Cross Section and Map Trace of a Fault
Page 1/1
Draw an east-west cross section across the northern part of the structure contour map in Fig. 6.53.
Suppose a fault that dips 40° south cuts the structure in the blank area between the arrows. What
would its trace be on the structure contour map? Is the fault normal or reverse? Draw a north-south
cross section showing the fault.
