STEREOGRAPHIC PROJECTION
Plotting normal to a plane 90/40 40 E B Draw the great circle with attitude 90 240. count 90 degree along EW from D,, mark the point P It is the projection of the normal to the plane 90 240
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 Bedding300∠40 Solve the apparent dip along the orientation of 335 degree 1. Plot the bedding and get the arc EHF 2. Mark 335 on the primitive Circle at point d 3. Link d'o intersecting at H 4. Count D'H along WE or NS It is the apparent dip
Solution for apparent dip from true dip Bedding 300∠40 Solve the apparent dip along the orientation of 335 degree. 1.Plot the bedding and get the arc EHF. 2.Mark 335 on the primitive Circle at point D’ 3. Link D’O intersecting at H’ 4.Count D’H’ along WE or NS. It is the apparent dip
