I am trying to solve the following question but cannot figure out how: A layer of limestone has a strike of East to West on a hilltop, and an apparent dip of 40 degrees on the vertical hillside trending N35E. What is the true dip angle and quadrant?

  • $\begingroup$ This sounds a lot like a homework question to me. Have you asked your peers, or the teacher, or consulted the course material on how to solve this? $\endgroup$

  • $\begingroup$ Hint: the apparent dip will always be less than or equal to the true dip. There are a number of ways to approach the calculation, depending on the precision you need. This is essentially a trigonometry problem. Look up how to use fold lines or stereonets $\endgroup$
