Document Summary
A way to plot/analyze 3-d data like strikes and dips in large numbers. These are the strike and dip measurements of faults in this area. They are being analyzed for the stress that created them (paleostress) Parallel to the hinge line (measured as trend and plunge) Doesn"t change if the fold rolls to the side, but does change if the. Goes through the hinges of the folds, strike-and-dip, changes as it rolls side to side, but not plunge. How the fold is rolled or plunged. Mapping (would be helpful for your xsection?) Note fault steepness also shows up on stereonet. (closer to the center. Normal faults tend to dip around 60-70 degrees, reverse or thrust faults dip at around 30 degrees and strike-slip faults are close to vertical. The numbers on the outside are the azimuth relative to north. The lines on the inside are dip/plunge (angle from horizontal)
