Elementary Techni
/ 5.
A slickenside surface dips N10°E,80°W. Fibrous slickenlines on the surface trend
N60°W.
(a) What is the plunge of the lineation?
(b) What is the rake of the lineation on the slickenside surface?
6. The true attitude of bedding at Flagstone, New York, is N41°W,65°NE. What is
the apparent dip of bedding on a vertical quarry face that trends N20°E?
A shale bed has the attitude N65°W,42°SW. What is the apparent dip of the bed
in the direction S85°W?

8. The apparent dip of bedding on a quarry wall is 23°,S48°W. On a second quarry
wall, it is 34°,N55°W. What is the true strike and dip of the bed?
V 9. In the Granite Wash Mountains of Arizona, bedding in a flysch sequence is oriented
N47°E,34°NW. A spaced cleavage in this unit is oriented N22°E,68°SE. The
intersection of bedding with cleavage produces a pronounced lineation that is
visible on bedding-plane surfaces. What is the attitude of this lineation?
10. A sandstone bed strikes 140° across a stream. The stream flows down a narrow
gorge with vertical walls. The apparent dip of the bed on the walls of the gorge is
25°,095°. What is the true dip of the bed?
11. Along a curving road cut, two different apparent dips on the same contact between
a limestone bed and a shale bed were measured. The first was 42º,N30°W and the
second was 58°,S70°W. What is the strike and dip of the contact?
12. A fault plane displays two different sets of slip lineations. One set is oriented
22°,325°, and the other set is oriented 49°,041°. What is the orientation of the
fault plane that contains the two lineations?
