Contoured stereonet plot of poles to bedding from deformed Jurassic shales, Revneset, Spitsbergen. the different colors represent contoured data density with a 3% interval. The strongest concentration is greater than 15% of the data in a 1% area. Note the great circle girdle pattern evident here. The great circle shown is a computer best-fit solution generated by the program (Allmendinger, http://www.geo.cornell.edu/geology/faculty/RWA/programs.html). One could speculate that two limbs are evident in the two bullseye, and that the one limb is better represented and thus the folds may be asymmetric. Both limbs would be shallowly dipping (remember that the poles are at 90 degrees and so the poles plunge steeply, and here the NE dipping limb readings are more prevalent.
