Exercise 8.8.3
Construct the Fault Trace
Page 1/1
Construct the missing fault trace and missing marker horizon on both maps in Fig. 8.51 for a fault
throw of 40. Does the marker surface on the map belong to the hangingwall or footwall? Construct
one map to show one to be a normal fault and the other to be reverse. What is the heave and gap for
a point near the middle of each map?

a fault (dashed lines) and a
marker surface on one side
(solid lines). a Fault dips
south. b Fault dips north
