1 54006-STRUCTURAL GEOLOGY LABORATORY EXERCISE 2 TRUE AND APPARENT DIP PLANE INTERSECTIONS AND PLUNGES Students: 1. 2. 3. Date Submitted: RATING: A. APPARENT DIPS (Solve both through graphical and trigonometric solutions .) 1. The true strike and dip of a limestone bed is N30E and 20 NW, respectively. A cross section trending E-W is required through an area in which this unit outcrops. What will be the dip of the limestone in the cross section plane? 2. Apparent dips of a sandstone unit measured on 2 vertical quarry faces are 20 N10E and 15 N85W. What is the true dip and strike of the sandstone unit? (Note: apparent dip measurements consist of a dip value and the direction in which the dip has been measured.) 3. Along a road cut, a bed has an apparent dip of 45° in a direction of N30W°. The bed strikes N50E. Find the true dip. B. PLANE INTERSECTIONS AND PLUNGES (Graphical Method) 1. A bed with a strike and dip of N20E 40SE is intersected by a normal fault with a strike and dip of N30W 60SW. Determine the trend (dip and direction) of the intersection of the bed and

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
