Very informative video regarding fold analysis in steronet projection. Dear sir please upload more video regarding clasical structural analysis. Regards
I’m not quite sure what the point of the question is. The hinge line doesn’t have a strike. It has a trend and a plunge, which is given by the position of the pole to the pi-plane. If the question refers to the strike of the axial surface, the answer would be that this direction must be determined in the field or from geological maps.
@@Geology_clips So its not possible to measure the dip and dip direction of the axial plane from compass measurements in the stereonet? I tried it with help of Mortaza Pirouz' video "Fold Geometry - P29 - Stereonet" but it seems he confused the ILA with the dip of the axial plane. im very confused of these stereoplots and didn't get a full routine into the technique yet...
my main issue is, I have a subhorizontal ~35° limb and a ~70° overhanging limb, so i expect the axial plane to dip more horizontal than vertical, but with these methods I always end up with an axial plane dip of ~74° because the way I do it, it seems, the overhanging is not recognized as such.
I was told to not change the overhanging dip direction into the same as the subhorizontal, yet it seems to be a necessary step in this case to do this. If anyone can follow me: please correct me if I'm wrong 😌

What if the strike of the hinge line is unknown? How do we know it?

@@Geology_clips If I understood it right, the axial plane does not always have an equal angle to both of its limbs, right?
