Primary sedimentary structures
Faults (thrust system, extensional fault system, strike-slip fault system)
Joints (tension joints, conjugate joints,en echelon joints)
Folding (bending, buckling, flexural slip, flexural flow, passive folding, kinking)
Stereographic projection
STEREOGRAPHIC PROJECTION
Plotting normal to a plane 90 ∠40
Draw the great circle with attitude 90 ∠40, count
90 degree along EW from D’, mark the point P’.
It is the projection of the normal to the plane 90 ∠40
Solution for apparent dip from true dip
Bedding 300 ∠40
Solve the apparent dip
along the orientation of 335
degree.
