Omission of part of a sequence in a vertical borehole suggests

  • A.a thrust fault
  • B.a recumbent fold
  • C.a dome structure
  • D.a normal fault

Answer: D

Correct answer: a normal fault

A normal fault drops the hanging wall, so beds slide past one another and part of the sequence is cut out where the hole crosses the plane. The amount missing gives a minimum estimate of the throw. The converse test applies to reverse and thrust faults, which repeat beds rather than omitting them.
