1) Project on a Schmidt net, a fault plane with attitude 0500-60 and the slickenline recorded on it with pt 070 SE. Define the attitude of the slickenline (as a line in a space, i.e., 000-00) independently from the fault plane. 2) Project and define the attitude of the intersection point (or line) (IP) of the planes (F1) 050-60 and (F2) 280-70, (b) Project and define on the (F1), a point (or line) (L1) that is 90 away from the (IP), and project on the second plane (F2) a point (or line) (L2) that is the projection of the (L1) on the (F2) plane and define its attitude. 3) Define the bisector plane of the planes (F1) and (F2) and give its attitude. 4) Draw a cone around an axis R = 0300-10 with an angle a = 30. 1) Project on a Schmidt net, a fault plane with attitude 0500-60 and the slickenline recorded on it with pt 070 SE.
