Problem 4. The following are measurements of five lineations, taken at five đifferent
outcrops.
Locality
Attitude of outcrop surface
Pitch (rake) of lineation
N60W (300°), 84°N
N10W (350°), 30°E
N40E (40°), 70°S
N23W (337°), 30°W
N88W (272°), 45°N
104°

If these lineations are elements of a planar fabric within a rock, then they should all lie
within the same plane. If you find this to be true, what is the attitude attitude (strike and
dip) of this plane?
